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.

Amazon SP-API and Amazon Ads API expert building production integrations, data pipelines, MCP servers, and advertising automation for marketplace sellers and SaaS teams. I am an Amazon approved third party developer with PII access, 100% Job Success, and more than 900 Upwork hours. I replace spreadsheets, manual exports, and unreliable integrations with production systems that include official OAuth, logging, retries, monitoring, approvals, documentation, and a clear audit trail. WHAT I BUILD • Amazon SP-API integrations for orders, inventory, listings, finances, returns, reports, notifications, and multi-account applications. • Amazon Ads API systems for campaign reporting, Marketing Stream, search term analysis, budget and bid rules, and guarded write automation. • Private MCP servers and AI command centers for Claude or Codex. My largest production build connects Seller Central, Amazon Ads, Google Ads, and ShipStation through 130 tools. It supports an advertising account with 177,000 keywords through an approval queue. • Data pipelines and warehouses. I ingest Amazon SP-API, Amazon Ads API, Shopify, and Mercado Libre into BigQuery or PostgreSQL. One analytics build removed about six hours of weekly manual reconciliation for each analyst. • PPC and repricing automation. I build wasted spend audits, search term review, Buy Box monitoring, pricing strategies, and approval workflows. Changes are previewed and approved before they reach the account. • Complete products. I built RepriceLab, a Buy Box repricer used across more than 12 Amazon marketplaces by paying subscribers. SELECTED WORK • Andy Anand Chocolates: 130 tool AI command center covering Seller Central, Amazon Ads, Google Ads, and ShipStation. • HeadBlade: OAuth MCP server and BigQuery warehouse covering orders, listings, finances, and returns across four marketplaces. • SellAnalytix: real time Amazon analytics combining SP-API, Marketing Stream, and warehouse data. • Kapow Meggings: unattended daily Amazon and Shopify listing audits with workbook reporting. • Gun Planet: two way Shopify inventory and order synchronization for a regulated marketplace. • DeLuca Consulting: Amazon Ads operations supported by custom command center tooling.

One of the few freelancers on Upwork with merged PRs into the Laravel core 😉. I build eCommerce platforms, SaaS products, and AI-powered tools - and I bring that same level of craft to every client project I take on. I am a big AI enthusiast. I build with Claude API and MCP integrations, use Claude Code and Cursor daily, and spend most of my weekends shipping side projects with AI. My latest is Qatodev, an AI-first QA automation platform. Before that, I spent 3.5 years scaling BrandsGateway, a B2B luxury fashion platform built on WooCommerce handling 60k+ products. Fast communicator. Full ownership. Available any time.
