Cover image for From ACH to Card Payments:
From ACH to Card Payments: Building Scalable Payment Systems for US Businesses Over the past few years, I’ve worked closely with US-based businesses to design and implement secure, scalable payment systems across ACH, online card payments, and card-present (terminal) environments. My experience spans platforms like North.com (http://North.com), NMI, and other payment APIs—supporting everything from recurring ACH billing to fully integrated in-person payment solutions using physical terminals. On the ACH side, I’ve handled bank account verification, transaction lifecycles, and returns such as NSF and failed debits. ACH systems require careful management of delayed settlements, webhook events, and reconciliation—especially within US financial workflows. For online card payments, I’ve implemented secure gateways, tokenization, and optimized checkout experiences to ensure fast, seamless, and PCI-compliant transactions. I’ve also built and deployed card-present solutions, including: – EMV terminal integrations – Tap, dip, and swipe transaction flows – Device configuration and deployment – Real-time syncing with backend systems – Handling reversals, refunds, and partial approvals A critical part of every integration is compliance and security. My work ensures: – PCI DSS compliance for card data protection – Tokenization (no sensitive data storage) – Secure API authentication and encryption – Reliable webhook handling and audit-ready transaction logs From a technical perspective, I specialize in building robust API integrations, webhook listeners, retry mechanisms, and fail-safe systems that continue to operate reliably under real-world conditions. Key solutions I’ve delivered: – ACH debit and recurring billing systems – Online card payment integrations with secure token flows – Card-present terminal integrations – Real-time transaction systems using webhooks – Payment failure handling and reconciliation logic – CRM and internal dashboard integrations Working in the US payments ecosystem has given me deep exposure to compliance requirements, operational challenges, and the importance of building systems that are both secure and scalable. My focus is simple: build payment systems that are reliable, compliant, and seamless—whether online or in-person. Open to collaborations in fintech, payments, and API integrations.

Cover image for I wish I had it
I wish I had it months ago. (Launching Proult - Desktop App) I spent 20 minutes looking for a Stripe credential. I checked my notes. My browser bookmarks. Old chats. Random text files. Not because I forgot it. Because I couldn't remember where I had saved it. That's when I realized the most dangerous phrase in a developer's workflow isn't: "I forgot." It's: "I've saved it somewhere." As freelancers, students, developers, and builders, we constantly juggle multiple projects simultaneously. And each project comes with its own ecosystem of information: • Client details • Credentials and passwords • API keys and secrets • Domains and hosting accounts • GitHub repositories • Deployment links • Meeting notes • Project requirements • Time logs and deadlines The problem isn't that we don't save this information. The problem is that we save it everywhere. -A Notepad file for credentials. -A spreadsheet for clients. -A project management tool for tasks. -Bookmarks for links. -Chat messages for "important" details. And before long, finding information takes more time than using it. After one too many "I know I saved this somewhere" moments, I decided to build something for myself. A single place where every project has its own secure workspace. Not just for storing passwords, but for managing everything related to that project: clients, credentials, API keys, notes, services, links, statuses, and time tracking. That's how "𝐏𝐫𝐨𝐮𝐥𝐭" started. So over the last few days, I've been building Proult, A local-first desktop application designed to keep everything related to a project in one place. -AES-encrypted credentials, API keys, and secrets -Project and client management -Built-in time tracking -Organization through project domains (Freelance, Personal, Organization, University) -Global search across projects, clients, credentials, and services -Full import/export support so your data always remains yours -Pinned projects, tags, notes, deployment links, and service management -Local-first architecture; no cloud dependency, everything stays under your control Still polishing it, but building it has already improved my own workflow significantly. Turns out, the best developer tools are often the ones built to solve your own frustrations first.

Cover image for Conflux – Frontend Design Showcase
Conflux – Frontend Design Showcase (MERN Stack Web Application) I’m pleased to share the frontend design of Conflux, a real-time communication web application built using the MERN stack, with an integrated AI assistant named Conflux AI. This stage of the project is focused exclusively on frontend architecture, UI/UX design, and component structuring. The objective is to establish a scalable, intuitive, and production-ready interface before initiating backend development. 🔹 Frontend Design Highlights Clean and modern real-time chat interface optimized for desktop web Structured conversation list with user previews and timestamps Dedicated AI assistant interface (Conflux AI) designed for future intelligent interactions Dark-themed, professional UI for enhanced usability and focus Modular and reusable React components prepared for backend integration Responsive layout ensuring consistency across screen sizes ⚠️ Current Status: All features shown are part of the frontend design layer only. Messaging, authentication, and AI responses are currently represented at the UI level. 🔹 Upcoming Development (Backend – Step by Step) Secure user authentication (login & registration) Messaging between registered users Real-time communication using Socket.io (http://Socket.io)Database integration with MongoDB AI-powered features via Conflux AI Voice and video calling functionality This design-first approach ensures a strong technical foundation, allowing backend features to be integrated efficiently and at scale. Looking forward to transforming Conflux into a fully functional, real-time communication platform. Feedback, suggestions, and professional connections are always welcome.

Cover image for Conflux AI is a full-stack
Conflux AI is a full-stack intelligent chatbot built with Python FastAPI backend and a custom vanilla HTML/CSS/JS frontend — designed to feel like a conversation with someone who actually listens. AI & Models: Groq API runs LLaMA 3.1 8B for fast responses and LLaMA 3.3 70B for complex reasoning. Google Gemini 2.0 Flash handles image analysis via REST API with automatic fallback to Gemini 1.5 Flash and 1.5 Pro. Agent Layer: LangChain + LangGraph power ReAct agents that decide whether to search the web, read a document, or answer from memory before responding. Real-Time Data: A custom Apify service delivers live news, crypto prices, and trending topics — bypassing the LLM entirely for fresh, hallucination-free data. Document & Image Intelligence: PDFs are ingested via PyPDFLoader with auto-summarization. Images can be uploaded, attached, or pasted from clipboard and analyzed through Gemini Vision. ReportLab generates downloadable PDF exports of any response. Auth: Firebase Admin SDK verifies JWT tokens server-side with full Google and email sign-in support. Frontend: Three-panel dark UI with a complete CSS animation system — messages fade up on entry, AI responses render character-by-character via a custom typewriter engine, and dynamic follow-up suggestions update after every response with staggered cascade animations. Emotional Intelligence: A fully custom keyword-based engine detects 10+ emotions in real-time — happy, sad, anxious, angry, curious, and more — adapting the AI's tone, language, and empathy level with every single message. Mood history is tracked per authenticated user with trend analytics. Stack: FastAPI · LangChain · LangGraph · Groq · Gemini · Firebase · Apify · ReportLab · highlight.js · Vanilla JS Conflux AI v5.1 — Built by Muhammad Noman Ijaz, Lead Engineer at Conflux. March 2026.
