RxApp — Enterprise ERP, AI Operations & Client Lifecycle Management Platform
Architected and engineered a comprehensive, custom ERP/CRM and business operations suite designed to centralize client management, sales pipelines, recurring service catalogs, project delivery phases, and AI-driven proposal generation.
Core Architecture & Technical Highlights:
• Modern Frontend: React 19 SPA built with TypeScript, React Router v7, TanStack Query v5 for server-state caching/optimistic UI, and Tailwind CSS v4 design system tokens.
• Modular Backend API: Node.js and Express.js layered architecture with Mongoose (MongoDB), Helmet security headers, JWT stateless authentication, and express-validator sanitization.
• Google Gemini AI Integration: Powered by @google/generative-ai with an intelligent dynamic model fallback chain (Gemini Flash series), dynamic runtime API key hot-swapping, and Xtreme-AI role-filtered knowledge base chat.
• 3-Stage AI Proposal & Scoping Engine: Interactive requirements extraction, technical dimensioning, commercial quotes with multi-installment terms, and automated technical runbook generation.
• Granular RBAC: Strict 5-tier Role-Based Access Control (SuperAdmin, Executive, Dev Director, Commercial, Financial).
• Sales & Billing Pipeline: Multi-currency invoice tracking, payment receipt processing (Multer), and phase-based project scheduling.
Stack: React 19 • TypeScript • Node.js • Express • MongoDB • Google Gemini API • TanStack Query • Tailwind CSS v4

Tired of manually posting to Facebook & YouTube every single day? 😴
I just built an AI-powered automation system that handles it all for you.
Here's what it does:
✅ Auto-schedules posts across Facebook & YouTube from a single Google Sheet
✅ Gemini AI optimizes your content for maximum engagement
✅ Intelligent comment replies — AI understands comments & responds contextually (in Bangla!)
✅ Thumbnail management — automatic upload & playlist organization
✅ Real-time tracking — all post URLs logged back to your sheet
The result?
Zero manual posting
100% consistency
5x faster workflow
Professional-grade automation
This is built on Make.com + Gemini AI + YouTube & Facebook APIs — fully scalable, zero coding required for clients.
Perfect for:
🎯 Content creators who post daily
🎯 Digital agencies managing multiple accounts
🎯 E-commerce businesses needing consistent presence
🎯 Anyone tired of the posting grind
If you're handling social media manually, you're leaving time (and ROI) on the table.
Automation isn't luxury anymore — it's necessity. 🚀

Created a demo AI automation workflow for lead capture and follow-up. The workflow captures leads through Google Forms, stores data in Google Sheets, sends automated email responses, updates a CRM, and notifies the team through Slack. This project demonstrates my skills in AI automation, workflow design, integrations, and business process automation.
Lead capture and follow-up are excellent areas for practical AI automation because missed responses directly affect revenue. A useful system should capture the enquiry, understand the lead’s intent, update the CRM, notify the right team member, and trigger appropriate follow-ups...
Recently added one of my ongoing projects to my Contra portfolio — ChatCLB.
I’m working on it as a Lead Full-Stack Engineer across ASP.NET Core, React, PostgreSQL, authentication, third-party integrations, and AWS/Kubernetes infrastructure.
One of the things I enjoy most about this project is working across the full product lifecycle — from architecture and APIs to frontend workflows, integrations, deployment, and production troubleshooting.
Currently continuing to build new features and integrations as the platform evolves.
Always interested in connecting with teams building SaaS products, APIs, or complex web applications.
The range of infrastructure here is impressive—especially the way a technical stack like this is being shaped into a clear, usable product. The reusable components should make future iterations much smoother.
