Architected and implemented core infrastructure across TaxMate and GigFlow, enabling scalable AI and automation workflows from backend services to user-facing apps. Designed a modular microservice architecture integrating OCR pipelines, RAG-based LLM agents, and AI-driven tax document parsing using LangChain and OpenAI APIs. Engineered database schemas and ETL pipelines to unify gig-platform data (e.g., Uber, Lyft, DoorDash, Fiverr) for consistent synchronization of financial and tax records. Built high-throughput APIs using FastAPI and Node.js (TypeScript) for data ingestion and financial transaction handling. Contributed to React and React Native interfaces, including real-time analytics dashboards. Deployed and monitored distributed services on AWS (Lambda, S3, EC2) using Docker and GitHub Actions with CI/CD and automated testing.

Designed, built, and optimized server-side systems powering a cross-platform fitness application including workout tracking, progress monitoring, wearable integrations, and AI-driven recommendations. Built and maintained FastAPI backend services with REST and GraphQL endpoints for analytics and real-time user data. Integrated Stripe flows for subscriptions, billing, and webhook handling. Developed AI-powered fitness recommendation logic using the OpenAI API. Designed optimized PostgreSQL schemas and queries to ensure fast, reliable processing across mobile and wearable integrations.

Developed and optimized server-side systems for a booking, scheduling, and membership management application. Built and maintained Laravel/PHP backend services and scalable RESTful APIs for bookings, scheduling, user accounts, and membership workflows. Integrated payment gateways (Stripe, PayPal, Mollie) including secure transaction flows and webhook handling with subscription logic. Implemented real-time notifications using Firebase Cloud Messaging (FCM) and server-side event triggers. Designed optimized MySQL schemas to improve query performance and data reliability under high traffic. Collaborated with mobile and product teams in Agile sprints, supporting API design, testing, deployment, and release management for App Store and Google Play.
