Full-stack developer building production backends, payment systems, and AI-integrated tools. I work primarily with Python (FastAPI), TypeScript/React, PostgreSQL/Supabase, and Stripe — with hands-on Claude API integration when AI belongs in the stack, not bolted on. I ship the parts of a system that have to actually work in production: payments and webhooks, auth and access control, API integrations, deploys, and the backend logic underneath. I build for reliability — not demos. Recent production work: - Member portal with Stripe subscriptions, Apple Pay, multi-currency checkout, and Supabase- gated access. FastAPI + PostgreSQL + Railway, 5★ verified delivery - Market-data MCP server for Claude Desktop and agent clients — workflow-shaped tools, FastMCP, open source on GitHub - TradingView → Claude → Telegram approval pipeline for AI-assisted decisions with human-in-the-loop confirmation - Bybit futures bot suite: multi-symbol live execution, ATR trailing stops, backtest engine, parameter optimizer - Pine Script indicators with multi-timeframe logic and webhook integration for automated alert delivery Specialized in trading systems and Claude/MCP integration, but the core skill is shipping backends that don't break. If you're building a SaaS, integrating Stripe, wiring Claude into a workflow, or automating a trading system — happy to talk.

I’m a Python software engineer and system builder with strong experience in quantitative trading systems as well as AI-assisted web product development. On the trading side, I design, code, and deploy data-driven strategies for stocks, futures, and options, working with platforms such as QuantConnect, TradingView (Pine Script), and ThinkorSwim, along with custom Python backtesting and automation pipelines. Alongside trading systems, I build real application MVPs and internal tools using Lovable + Supabase when speed, iteration, and production readiness matter. My product development work typically involves: -Designing MVPs with real application logic (not landing pages) -Authentication, permissions, and structured data models -AI-assisted workflows (content processing, summaries, analysis) -Dashboards, learning platforms, and internal tools -Scalable architecture that can grow beyond the MVP stage Clients work with me when they want: -Clean, reliable Python systems -Serious trading or data logic (not toy scripts) -A functional product MVP built quickly but thoughtfully -Someone who understands edge cases, scalability, and maintenance If you’re building something that needs logic, structure, and reliability, I can help you design it properly from the start.
