AI systems that run in production.

A designer-developer hybrid with ~25 years hands-on. I build AI products end-to-end — speech recognition, speech synthesis, RAG and agents — and run them myself on security-hardened Linux servers. Whole platforms, shipped solo from architecture to deployment.

Profile

From the model to the interface — one person, the whole stack.

Ferhat Baysal
Ferhat Baysal Senior Full-Stack & AI Engineer · Thundorf

Senior full-stack & AI engineer with ~25 years hands-on across software, design, databases and content. I ship complex production systems end-to-end and solo — from the model pipeline through the API to the polished, SEO-optimised interface.

My focus is applied AI that actually ships: custom speech recognition and synthesis, fine-tuned language models, RAG pipelines with vector search and reranking, and tool-using agents. The most visible result is mazdek.ai — the first AI platform purpose-built for the Kurdish language — where I am lead developer and own the core technology.

On top of that sits deep command of modern TypeScript stacks (Next.js, Fastify/tRPC, Node.js/Bun) and the infrastructure underneath: Docker, Traefik, PostgreSQL/pgvector, Redis, object storage and search indexes — 20+ services on a single hardened Ubuntu host, with rolling, zero-downtime deployments. A designer-developer hybrid who has delivered web platforms, e-commerce, custom CRMs and automations for international clients — across language barriers, through precise, fully-written async collaboration.

AI engineering

AI that runs in production — not just in a notebook.

01

Language models & agents

Selecting, fine-tuning and embedding LLMs into products: tool-using agents, structured output, guardrails and cost control — self-hosted (Ollama) or via API, depending on privacy and budget. In production e.g. as mazdekClaw on mazdek.ch: an AI agent that works directly in client projects' code over SSH.

02

Speech: ASR & TTS

Custom speech recognition and synthesis, trained for languages the large vendors neglect. In mazdek.ai that means 1,220+ synthetic voices, voice cloning and live two-way interpreting.

03

RAG & knowledge systems

Documents, audio and video turned into searchable knowledge: embeddings, vector search with pgvector, reranking, and sourced answers instead of invented ones.

04

AI infrastructure

Inference servers, model deployment, queues, caching and observability — containerised, replicated behind a gateway and rolled out progressively, without users noticing a thing.

All four areas are live in production today, running on infrastructure I operate myself.

2025 — Present

Lead Developer & Architect

mazdek AI (mazdek.ai) ↗

AI platform for the Kurdish language · mazdek GmbH, Switzerland

  • Lead developer of the platform: speech recognition, speech synthesis, translation, spell checking and AI chat designed and built as one coherent product — the first AI platform purpose-built for Kurdish.
  • 1,220+ custom voices with voice cloning, ASR for Kurmanji and Sorani, translation across 255+ languages, and Rastnivîs, a spell checker covering every Kurdish dialect plus 90+ other languages.
  • RAG architecture on PostgreSQL/pgvector with embeddings and reranking for sourced answers; projects, file uploads and audio/video analysis inside the AI chat.
  • End-to-end SaaS operation: authentication, subscription and token billing via Stripe, a multilingual Next.js frontend, and deployment on my own Docker infrastructure with Traefik, replicated web instances and rolling zero-downtime updates.
2024 — Present

Lead Developer & Architect

mazdek (mazdek.ch) ↗

Independent project · AI-powered digital solutions · now mazdek GmbH (founded 2026)

  • Single-handedly designed and built mazdek over two years — an AI-powered digital-solutions platform (web apps, e-commerce, AI products) — owning the entire stack alone, from architecture to deployment.
  • Designed and built mazdek's AI agent system: 19 specialised agents — from ATHENA (full-stack) and HERMES (mobile) to PROMETHEUS (AI), HEPHAESTUS (DevOps), ARES (cybersecurity) and ARGUS (project guardian) — each with its own profile, page and admin configuration; IRIS runs in production on client projects as mazdekClaw.
  • Built mazdekClaw, an AI project assistant built on a tool-using LLM agent: in ticket mode it files revisions, bug reports and meetings; in code mode it reads, edits and builds the client's project over SSH, directly inside their Docker container — reachable from the client portal and over WhatsApp.
  • AI project wizard that qualifies leads with an LLM (streamed follow-up questions) and generates the customer, order and project brief — guarded by e-mail OTP, a daily budget and rate limits; plus a client portal with magic-link login, live updates (SSE), files, revisions and online payment.
  • Admin and finance back office: Swiss QR-bill PDFs, payment reconciliation via camt.054 import matched on the QR reference, expenses, e-mail threading through a Cloudflare Email Worker and a delivery cascade (ZeptoMail → Resend → SMTP). Stack: Astro 5, Next.js 15, Hono, Drizzle/PostgreSQL, BullMQ, MinIO, Docker.
  • Built PEYAMIO (peyamio.ch), a B2B WhatsApp ordering platform for restaurants: WhatsApp Business API, Stripe payments and multi-tenant architecture.
  • Provision and operate bare-metal Linux servers entirely from the terminal — no control panels — with Ubuntu setup, OpenLiteSpeed / Nginx, Redis caching, security hardening and zero-downtime deployments.
2017 — Present
