Expert-Vetted Ex-Amazon Engineer | Full-Stack Python | $1M+ Client Systems 🏆 Expert-Vetted | Ex-Amazon Engineer | 10+ Years Experience 💰 $500K+ earned on Upwork | 85+ projects 🎯 Top Rated Plus | 100% Job Success Score 🚀 100+ production builds | 40+ AI & automation systems ⭐⭐⭐⭐⭐ “I have worked with several similar service providers and been impressed with Asad and his team on every level. Excellent communicators, proactive in problem-solving, and the output was production-ready from day one.” — Julian M. I'm a former Amazon engineer and senior Full-Stack Python Developer who works with founders and product teams to turn ideas, broken workflows, and ambitious requirements into production systems that generate revenue, reduce operational work, and scale. I help founders and companies turn complex product ideas and operational problems into revenue-generating software and automation systems, including platforms supporting $1M+ businesses and millions of real-world assets. Selected Results 🔶 2M+ Vehicle Autonomous Drone Platform Built an autonomous computer-vision platform for an automotive logistics operation managing 2M+ vehicle movements/year across 50-acre lots. Drones using YOLO-OBB, OCR and real-time inventory reconciliation replaced manual yard searches. Result: synchronization dropped from hours to under 15 minutes at 99.9% accuracy, operational efficiency improved 90%, and the client absorbed 2M vehicles/year without adding headcount. 🔶 $70K AI PropTech Platform Led an AI-powered real estate platform from architecture through production using React, TypeScript, Python, OpenAI and Supabase. 🔶 Multi-Tenant AI SEO SaaS Built from zero to launch with 5+ user roles, 20K+ tracked keywords, AI content workflows, analytics and automated reporting. 🔶 10K+ Profiles/Day AI Lead Engine Built a Python + n8n enrichment pipeline processing 10K+ profiles/day and reducing manual research by 80%. 🔶 Voice AI Agent Platform Built production AI voice/chat agents integrated with CRM, booking and operational systems, including retry logic, monitoring and error handling. What I Can Own ✔️ Full-Stack SaaS: React, Next.js, TypeScript, Python, FastAPI, Flask, Django ✔️ AI Systems: OpenAI, Gemini, LangChain, RAG, AI agents, AI assistants ✔️ Backend & APIs: PostgreSQL, REST APIs, authentication, RBAC, integrations ✔️ Automation: n8n, Zapier, Playwright, Selenium, CRM & operational workflows ✔️ Infrastructure: AWS, Supabase, Vercel, Stripe, CI/CD Why Clients Hire Me You don't need to hand me perfectly written technical tickets. Give me the business problem or product goal, and I can work through the requirements, architect the solution, build the frontend and backend, integrate AI/automation where useful, and get it reliably into production. Idea → Architecture → UI → API → AI/Automation → Production That makes me particularly useful for: → Founders building AI-native SaaS products → Companies turning manual operations into software + automation → Teams that need a senior engineer to take ownership of a major feature → Agencies needing reliable senior engineering capacity → Existing SaaS products that need to scale, stabilize or ship faster Best fit Projects where engineering has a measurable business outcome: launching a product, increasing revenue, automating expensive work, replacing fragmented systems, or scaling an existing platform. Not a fit: $500 landing pages, basic WordPress customization, crypto/trading projects, or projects looking purely for the lowest hourly rate. If you need a senior engineer who can take a product from “here's what we're trying to accomplish” to “it's live and working in production,” let's talk.
