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 developed Chezify, a high-performance

I developed Chezify, a high-performance mobile application tailored for a local fast-food restaurant. The goal was to bridge the gap between a traditional physical storefront and a modern digital presence by providing a seamless, branded ordering interface. The Technical Challenge The focus was on creating a Modular Architecture that allows the business to scale its menu effortlessly. I designed a library of reusable Flutter widgets (FoodCards, DealCards) that ensure UI consistency across the entire app while maintaining a strict 60 FPS performance target for a premium user experience. The Results Optimized Performance: Achieved silky-smooth scrolling and transitions, even with high-resolution imagery. Scalable Design: Built a custom UI/UX from scratch using Dart, avoiding generic templates to ensure brand uniqueness. Business Integration: Developed an "Exclusive Deals" logic to drive higher order values through targeted combo offers.

Cover image for I engineered a high-performance, browser-based

I engineered a high-performance, browser-based 3D experience that allows users to manipulate a system of 15,000+ particles using real-time hand gestures. This project explores the intersection of Web Graphics and Computer Vision, turning a standard webcam into a spatial controller. The Technical Challenge The main hurdle was achieving a "haptic" feel ensuring the particles reacted instantly and smoothly to physical movements without lag. This required mapping 2D webcam coordinates into a 3D coordinate system and calculating volumetric transformations on the fly. The Solution & Workflow High-Performance Rendering: Used Three.js and WebGL with additive blending and custom color mapping to render a massive particle count at a consistent 60 FPS. Real-time Inference: Integrated Google MediaPipe to track 21 3D landmarks per hand directly in the client-side browser, eliminating the need for a backend. Dynamic Math: Implemented custom lerping (Linear Interpolation) and gesture thresholds to create fluid movements, such as a "fist-clench" collapsing the particles into a sphere and an "open-palm" expanding them into a galaxy. The Results Created a fully immersive, zero-latency interface that demonstrates the power of the modern web for interactive AI applications.

Cover image for I built a custom AI

I built a custom AI Voice Agent for a service-based business to automate their appointment booking process. The system handles inbound/outbound calls, qualifies customers, and manages scheduling without any human intervention. The Technical Challenge The goal was to create a "robust" agent that could handle natural human speech patterns including stammers or mid-sentence changes while maintaining the conversational flow. I needed to bridge the gap between high-fidelity voice synthesis and real-time database management. The Solution & Workflow Voice & Logic: Integrated ElevenLabs for realistic vocal performance and Retell AI (or similar) for low-latency conversational handling. Automation Engine: Built complex workflows in n8n to process the data gathered during the call. Real-time Integration: The system automatically cross-references and updates Google Calendar, sending instant confirmations to both the client and the customer. The Results 100% Automation: Successfully moved the client from manual phone bookings to a fully autonomous system. Error Handling: Programmed the agent to stay on track even when users provide vague or self-correcting input.

Cover image for I developed a real-time Air

I developed a real-time Air Drawing Application that uses Computer Vision to transform hand gestures into digital input. By utilizing a standard webcam, the app allows users to draw, erase, and select colors in mid-air without any physical contact with the screen. Key Technical Features: Hand Tracking: Integrated MediaPipe to track 21 specific hand landmarks with high precision and near-zero latency. Gesture Logic: Programmed custom state-switching—using a single index finger for "Drawing Mode" and a two-finger gesture for "Selection Mode" to navigate the UI. Real-time Rendering: Leveraged OpenCV for video processing and to create a dynamic, responsive canvas overlay. This project demonstrates my ability to build Human-Computer Interaction (HCI) tools and implement real-time AI solutions using Python.
