I ship AI products in weeks, not quarters

I'm Samir Maikap. I help founders and product teams turn an AI idea into a product people rely on, in weeks. You get one senior engineer who plans with you every week, builds with AI coding agents, and proves it works with tests and evals before it ships.

Catalog: AI fashion with virtual try-on

Try-on clips rendered on the shopper's own selfie, with a one-shot fallback when a model refuses. The catalog grows from what shoppers search for.

Experience

I'm a Senior AI Product Engineer based in Kolkata, India, working US hours. Since 2017 I've built products end to end for US founders and agencies: 49 projects across web, mobile and AI, including the Bartesian cocktail-machine app, Catalog's AI stylist, and the FITT product line I've led for MCS Media for eight years.

Teams hire me when an AI feature has to work in production, not just in a demo. I scope the work in writing, build with AI coding agents, and measure AI output with evals before it ships. On Decize, that process took faithful debrief lines from 91.6% to 100% on a fresh holdout.

With the founders: Catalog (AI fashion), Feather (AI knowledge base) and The Quest (iOS game).

  • AIAI stylist with virtual try-on. Claude Haiku vision checks the selfie: one person, clear face, real photo. Seedance renders a 9:16 clip; if its content filter rejects it, the webhook retries once on Gemini. Every step is logged.
  • AIA catalog that stocks itself. Shopper searches are ranked, Claude filters junk terms and tags occasions, and products go live only with an image and tags. A Shopify portal onboarded 4 brands.
  • RAGFeather knowledge base. My call: drop NestJS for Supabase. Shipped in 5 weeks.
  • Platform8-network publishing, solo in 3 weeks. No duplicate posts on retries, an MCP server for AI agents, database-tested tenant isolation.
  • MobileCatalog Flutter app, sole engineer. App Store–approved after 5 review fixes.

How I made AI debriefs a team can trust

A debrief sums up what happened after a decision. If the model invents a single line, nobody trusts the ledger again. This is how I measured that risk and fixed it.

  1. 1
    Extractive by designEvery debrief line must be a word-for-word phrase from its source. Code drops any line that isn't.
  2. 2
    Blind judges, not vibesThe production function ran 3 times per case. Three blind LLM judges scored every line: 2 of 3 to pass, plus a tie-break judge.
  3. 3
    A stress set built from failure modes57 cases covering 19 ways a debrief goes wrong. First run: 391 of 427 lines faithful.
  4. 4
    Two prompt rules fixed itKeep both sides of a mixed answer. Plans, advice to others and sarcasm never count as "Next time".
  5. 5
    Proven on fresh dataThe bar was set before scoring: 97%. A new 36-case holdout, written after the fix, passed 221 of 221.
