If it can be built with software, I can ship it, and fast, because I run AI systems in production every day. Recently shipped, all real and verifiable: desktop OCR software for scanned books, delivered to a paying client and stress-tested on 2,000 pages (5.0 review). Audiobook production with author voice cloning and mastered narration. WhatsApp commerce campaigns for a D2C brand: broadcasts, deliverability repair, revenue-leak analysis. Cold email infrastructure with verified lists, SPF/DKIM/DMARC and warmup, my own campaigns measure 59% opens. A macOS dictation app I designed and built solo. Nine production systems running 24/7 on Cloudflare with crons, webhooks and dashboards. What I ship fast: custom AI agents (research, outreach, support, ops), workflow automation (n8n, Make, Zapier, custom), LLM integrations (OpenAI, Anthropic, OpenRouter), RAG and semantic pipelines, MCP servers, data extraction and enrichment, HubSpot/Salesforce/Apollo automation, web apps and dashboards (Next.js, FastAPI, Cloudflare, Supabase), audio/video AI (TTS, voice cloning, transcription). Background: 18 months as founding engineer at bhindi.ai ($4M raised), shipping production agentic systems. How I work: fixed scope, fast first deliverable, usually same day you unblock me. Honest about what I have not done before. I would rather show you a working sample than a portfolio promise. less -

Even at that scale, I still find it incredibly rewarding to see the systems I’ve built make someone’s work easier and contribute to the steady growth of their business. Even if you’re simply thinking, “I’m not sure what I need to build yet,” that’s completely fine. I’ll listen, ask the right questions, and work through the possibilities with you. Being able to watch a client’s business grow while continuing to grow alongside them is, for me, one of the most rewarding parts of this work. less
