AI Chatbots Should Do More Than Just Answer Questions 🤖 I’ve been building AI chatbot solutions that go beyond basic Q&A. A useful business chatbot should be able to understand your company’s knowledge, answer customer questions accurately, capture and qualify leads, trigger workflows, and connect with the tools your team already uses. Recent solutions I’ve worked on include: → Custom knowledge-base / RAG chatbots → OpenAI & LLM integrations → Website AI assistants → WhatsApp & messaging integrations → Lead capture and qualification → CRM & API integrations → Human handoff workflows → Conversation history & analytics → Custom admin dashboards The goal is simple: turn AI into a practical business tool—not just another chat window. If your business has repetitive customer questions, manual lead handling, or information scattered across documents and systems, a custom AI assistant can automate a significant part of that workflow.

🔧 Another website back online. Recently worked on Luna’s Ascension, a website that had gone down and was no longer functioning correctly. I diagnosed the underlying website/server issues, restored the site, resolved the problems preventing it from running properly, and brought the platform back online. Website recovery projects aren’t always about building something new — sometimes the real challenge is understanding an existing system, identifying what broke, and restoring it without disrupting the parts that already work. Work included: • Website troubleshooting & recovery • Server-side issue diagnosis • Existing codebase debugging • Website functionality restoration • Production environment fixes • Stability checks after recovery 🌐 Luna’s Ascension From broken websites to full-stack applications, I help businesses diagnose technical problems and get their platforms running reliably again.

A good donation flow needs dependable systems behind the screens. For Gabriel SGO, I built the NestJS/PostgreSQL backend for donor and school workflows, with PayPal donation processing, Redis/BullMQ background jobs, Mailgun email, and AWS delivery. The public experience helps Ohio donors estimate a contribution, choose a school, and understand the tax-credit process. I documented the backend work and real site screens here: https://contra.com/p/Ls6L2o7Y-gabriel-sgo-or-donation-and-school-allocation-backend

A college football roster is more than a list of stats when the goal is a Madden-ready draft class. For GridIronGC, I built the Node.js/TypeScript backend, conversion pipeline, and API, with Python stages and OpenAI-assisted data normalization. The live SaaS supports manual conversion, bulk uploads, and draft-class organization. I shared the real product screens and backend context in the case study: https://contra.com/p/3qRLLQ6c-grid-iron-gc-or-ai-assisted-player-conversion-backend

ESG reporting is a workflow problem as much as a data problem: teams need applicability rules, evidence, consolidation, review, and approvals before a report is ready. For OriginSustain, I built NestJS/TypeScript backend services, PostgreSQL and Redis/BullMQ processing, and AWS/Docker delivery with CI/CD. OpenAI API and RAG support part of the reporting flow. The screens here are from the product’s illustrative command center; the numbers are demo values, not client outcomes.

MyCarrier: DevOps & Cloud Transformation for Scalable Logistics SaaS Preview description: We helped MyCarrier move toward cloud-ready DevOps: adapted the system for microservices, implemented CI/CD and test automation, moved workloads to Azure, achieved 99.9% availability, decreased update delivery time to minutes. Full description: Problem MyCarrier was growing fast, and the monolithic codebase became harder and more expensive to maintain. It was heavy, resource-consuming, and less suitable for the client’s long-term scaling plans. The team also needed faster delivery processes, but changes in the codebase and cloud migration had to stay unnoticed by users. Their logistics workflows could not be interrupted. Solution IT Craft aligned the project infrastructure with a microservices architecture and prepared the system for cloud operation. The team started with a technical audit and developed the migration strategy consisting of 20-28 items. The process was divided into pre-migration, migration, and post-migration phases, thus the product could keep running while infrastructure changed step by step. The team moved non-critical standalone jobs to the cloud, connected virtual machines to Azure Storage Account, moved logging to MongoDB Atlas, and transferred user data and related processes to the cloud. New app functionality was released as microservices. IT Craft also designed and fine-tuned a CI/CD pipeline, automated infrastructure deployments, and reduced update delivery time through regression test automation. Results · Achieved 99.9% system availability. · Maintained high fault tolerance using three shared clusters. · Reduced update delivery time from hours to minutes. · Enabled Sprint focus changes every two weeks based on client priorities. Tech Stack: · Azure Cloud · MongoDB Atlas · Azure SQL · Azure App Service · Azure Functions · Azure Storage Account

We delivered Android and iOS apps with five-minute onboarding, secure chat, video calls, e-signatures, and data that stays current across devices. Full description: Problem Attorneys and clients at Legal Beagle were stuck moving paper between tools that didn't connect. The client wanted one legal SaaS product that lived on people's phones: secure messaging, fast attorney onboarding, e-signatures, and a shared space to work a case, same on Android, same on iOS. Solution IT Craft provided full-cycle mobile app development for Android and iOS. The team reviewed legal workflows, mapped mobile user flows, and built real-time features for secure messaging, video and audio consultations, document exchange, e-signatures, and case collaboration. Both apps were built to keep user data current across devices, so lawyers and clients could continue their work without losing context. IT Craft also integrated CRM systems and digital signature tools, including Clio and DocuSign, and set up cloud infrastructure for secure legal service delivery. The product included compliance-focused security, data protection, and a white-label setup for future expansion into new legal markets. Results · Delivered Android and iOS apps for a legal SaaS platform. · Added secure chat, video consultations, document workflows, and e-signatures. · Enabled real-time synchronization across mobile devices. · Reduced mobile attorney onboarding to 5 minutes. · Integrated CRM and digital signature tools, including Clio and DocuSign. · Developed a white-label version for expansion into new legal markets.

Adorama: 13 Years of 24/7 Support for a $500M+ E-Commerce Platform Preview description: We provided long-term 24/7 technical support for Adorama’s $500M+ ARR e-commerce platform, helping maintain 99.8%+ uptime, ship 2 releases per week, and keep team turnover at around 12%. Full description: Problem Adorama needed a long-term technology partner capable of supporting a complex e-commerce ecosystem while maintaining business continuity, preserving product knowledge, and scaling engineering capacity as the platform evolved. Solution Over 13 years of collaboration, IT Craft scaled from a single engineer to a 54-person team supporting multiple areas of the platform. Our engineers became part of the client’s product cycle, supporting frontend, backend, testing, monitoring, platform maintenance, and infrastructure optimization. The team helped keep the platform stable while releasing updates on a predictable schedule. IT Craft also supported recruitment, onboarding, team management, and retention, making sure new specialists joined quickly and product knowledge stayed inside the team. This setup gave Adorama continuous support for a high-revenue e-commerce platform instead of short-term development help. Results Maintained 99.8%+ uptime across a $500M+ ARR e-commerce platform. Scaled the dedicated team from 5 to 54 specialists. Delivered an average of 2 production releases per week. Maintained team turnover at approximately 12% throughout long-term cooperation.

Role-Based AI FAQ System: Right Answer for Every User, Instantly Preview description: We built a modular, AI-assisted FAQ platform where the LLM acts as an intelligent query router to a centralized knowledge base, reducing support workload by 40%–70% and providing public, investors, partners, and employees with accurate information. Problem The client is a manufacturer of advanced multifunctional materials. He wanted to ensure all interested users had access to relevant information quickly, reliably, and without placing an extra burden on the company’s experts. A conversational interface was required to enable users to ask questions in natural language and receive responses while keeping AI behavior controlled and transparent. Solution We designed a standalone OpenAI-powered FAQ module with a controlled-response engine that generates answers based on predefined information, taking roles and permissions into account. As it is separated from the client’s Vercel-based website, the integration takes place via an iframe, while account management and access level assignment are handled within Vercel CMS. When a user asks a question, the system filters the query based on the identified role (public, investor, partner, or employee) to eliminate data leakage. Then it applies the vector search to deliver an answer that is stored in the admin panel. The system also ensures that each response is accompanied by documents and links to Vercel pages based on available tags. Results The FAQ system reduces the average time needed to find information from 10–15 minutes to under 30 seconds through conversational search and centralized knowledge management. The support workload decreased by 40%–70%. Onboarding time for employees, partners, and investors decreases by 50–80% while the system grants instant access to structured answers. Tech stack: - OpenAI API for query understanding - VectorDB (pgvector) database for semantic question matching - PostgreSQL as a structured database for storing FAQs, tags, roles, and permissions - Python/FastAPI for backend and admin panel development - iframe for secure communication - Vercel CMS Vercel-hosted frontend integration

Spent an afternoon this week chasing down why a client's order dashboard took around 2.5s to load. Turned out the page was firing 300+ database queries. Classic N+1 problem. Every order in the loop was making its own separate trip to the DB just to grab the customer and product. One line fixed it. select_related() tells Django to pull the related rows in a single JOIN instead of querying them one at a time. 312 queries down to 3. Page load went from 2.4s to 0.08s. The annoying part is this never shows up on small datasets in dev. It only bites you in production once the table grows. So now I always check the query count in Django Debug Toolbar before shipping any list view. What's the worst N+1 you've run into?

Hit a classic Django trap this week and figured it's worth sharing since so many people are running into it now. I was adding an LLM feature to a Django app. The AI call takes a few seconds, so naturally I made the view async so it doesn't block a worker while waiting. Wrote the async view, called the ORM like I always do, and boom: SynchronousOnlyOperation: You cannot call this from an async context. Turns out Django's ORM can't just be called normally inside async code. The classic sync API isn't safe in an event loop, so Django protects it and throws this error instead. The fix is simpler than most people think. Since Django 4.1 the ORM has async versions of everything, same names with an "a" prefix. So objects.get() becomes await objects.aget(), create() becomes acreate(), save() becomes asave(). For loops over querysets, async for works directly. And for old sync code or third party libraries you can't change, wrap them with sync_to_async(). Why this matters right now: everyone is bolting AI features onto Django apps, and LLM calls are exactly the slow I/O that async is made for. Which means a lot of devs who never touched async Django are suddenly hitting this error for the first time. One honest caveat: transactions still don't fully work in async mode, so if you need atomic blocks, keep that path sync and wrap it. Anyone else made the jump to async views yet, or still happily on WSGI?
