Building systems that still run after I stop touching them.

Experience

Software Engineer · Milidia Teknoloji (Aug – Oct 2026)

  • WhatsApp AI assistants for two client platforms (Node.js, TypeScript). Every customer-facing sentence comes from a knowledge layer; the model only picks the topic. Urgent messages reach a person without the model being called, and the assistant keeps running on its rule layer if the model fails.
  • A furniture maker's custom-design and e-commerce platform, taken from an existing code base to delivery: storefront, NestJS/Prisma API, admin console, store portal and a cost engine.
  • Web applications with Next.js, TypeScript and Tailwind CSS.

Software Engineering Intern · BizYaz Bilişim (Jul – Aug 2024) — company management panel with PHP/Laravel, RBAC and a REST-backed SPA.

Selected work

Project What it does Stack
Fabric Production tracking for carpet weaving mills: OEE and downtime turned into lost lira, a morning briefing, a due-date risk radar, phone-photo defect logging, Poisson/CUSUM detection of faulty yarn lots and a tool-calling AI assistant with a rule fallback. 135 xUnit tests. Live demo C# · ASP.NET Core · EF Core
Metron Construction site management app for a civil engineer: daily reports, attendance, on-site quantity take-off, progress payments and work schedule — tablet-first and fully offline, 14 document types rendered to PDF on the device. 298 tests. Client work, source private. TypeScript · React Native · Supabase
TerraScope Climate-risk and urban-resilience simulation for Türkiye's 81 provinces and Istanbul's 39 districts, projected to 2050. ERA5 + CMIP6 heat, ESHM20 seismic hazard, live quake/fire/air data, H3 globe prototype. 29 tests. Source private. Python · Streamlit · H3
Titulus Live platform for a law practice — 2,468-article legislation library, daily Official Gazette feed, an admin panel the client runs alone. avukatmetinmaasoglu.com PHP · JavaScript
Anamnesis Retrieval-grounded assistant that answers only from what it retrieved and names the source behind every claim. Read-only by design, verified by a test. Live demo Python · FastAPI · RAG
LetheFS A file system that forgets on purpose, along the Ebbinghaus curve. Every action logged and reversible; never deletes silently. Live demo Python · FastAPI · WebSockets
Unicorn Search-and-rescue rover firmware. Raises its own Wi-Fi, serves its command centre from flash; control logic is unit-tested with no board attached. Live simulator ESP32 · C++
Helixir AES-256-GCM file encryption with scrypt, ciphertext rendered as a DNA sequence. Python · PyQt6

More: Aurora · Cardia (live demo) · BOZGUN · Orchidia

How I build

  1. Logic apart from hardware and models — so it can be tested on a laptop, in CI, with nothing plugged in.
  2. Uncertainty is reported, not hidden — a range instead of a false exact number.
  3. Modes are declared — simulated, fallback or live, the user is always told which.
  4. Only shipped features are documented — no roadmaps dressed up as features.
