Muhammed Fatih Koca
Summary
Engineer building AI agents, full-stack web apps, and native mobile products for US immigration law firms. Currently contracting with Path Law Group, where I ship production systems for visa eligibility screening, intake-meeting automation, and client-facing marketing pages. Comfortable taking a project from a brand design to a shipped product, and from a vague requirement to a production AI pipeline.
Experience
- Built the firm's AI Visa Screener: a GPT-5 pipeline that evaluates HubSpot intake questionnaires against the USCIS criteria for eight visa categories (O-1A, O-1B, EB-1A, EB-1B, EB-2 NIW, H-1B, L-1, E-2). Verifies claims with real-time web research, returns a 13-field structured assessment, and writes back a richly formatted note plus a one-page PDF brief to HubSpot.
- Built Meeting Transcript Automation: HMAC-signed Fireflies webhook → OpenAI structured extraction of 14 fields → HubSpot deal + contact updates, transcript & AI-summary PDFs to HubSpot Files, follow-up email draft, optional Notion sync. Dual trigger with retry + per-contact throttling.
- Shipped a production Next.js + Tailwind static-export marketing landing for the firm's E-2 visa practice. Autoplay hero video, smooth scroll, Embla carousels, attorney profile cards. Same code the firm ships today.
- Calibrated the AI evaluator against 977 historical Path Law cases and 19 ingested USCIS / DOS rule documents (7,646 lines); core evaluator module is ~520 lines of TypeScript.
Selected Projects
Native iOS (SwiftUI) and Android (Kotlin / Jetpack Compose) app concept for tracking USCIS case status across 50+ form types. Receipt-number polling, push notifications, Visa Bulletin viewer, document storage, and citizenship-quiz practice. 21 production-ready feature screens.
Six specialised agents on a Notion-style workspace: PetitionDrafter, RFEResponder, EvidenceCurator, PolicyResearcher, IntakeAgent, DeadlineWatcher. Multi-tenant Postgres with row-level security, shared pgvector memory, and a typed LLM router across OpenAI and Anthropic.
Translated high-fidelity client designs into production Next.js + Tailwind + Framer Motion landings end-to-end for E-2 visa and boutique-firm brands. Pixel-accurate conversions, no template builders.
