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 -
