ELECTRICAL & ELECTRONICS ENGINEER (B.SC.) · ANKARA
Systems engineering, built with AI.
Concept, architecture and quality assurance are mine. Implementation is carried out together with AI coding agents. I started out with a soldering iron — and that still shapes how I build systems.

How I work
I build software with AI assistance, and I say so openly. Not as a caveat but as a method: the machine writes faster than I ever could. The question that remains is a different one — who decides what gets built, and who guarantees that it is right.
Concept & architecture
mine
Problem definition, domain model, system boundaries, data model. Architecture decisions are recorded as ADRs — with the reasoning and the alternatives that were rejected.
Implementation
with AI coding agents
Claude Code and OpenAI Codex, governed by agent contracts (CLAUDE.md, AGENTS.md) that set out what an agent may and may not do. On larger projects two lines run in parallel.
Quality assurance
mine
Tests, type checking, linting, Lighthouse thresholds, security boundaries. What does not pass these gates does not ship — regardless of who wrote it.
The hard decisions in my projects were never coding questions. They were: what must this system not do? Which claim needs a source? Where does information end and legal advice begin? Those are not questions you delegate.
In focus
Local AI Homelab
The "localai" CLI + a real multi-device infrastructure
Running Private repository
Where hardware meets AI systems: a security-first CLI and a lab that actually runs.

Aykaralar Platform
Running Client project
Architecture decision
Search engines are no longer the only readers of a website. Alongside JSON-LD, sitemap and robots.txt, the platform ships an experimental llms.txt — machine-readable for the AI systems that increasingly sit between a customer and a company. The lead form is multi-step and triple-guarded (honeypot, Turnstile, rate limit), and consent records are pseudonymised. If the database goes down, the site still serves content from a safe fallback.
My role
Concept, monorepo architecture (8 packages), data model, deployment pipeline and quality gates. First client: a construction company in Ankara.

Aykaralar OS
An operating system for small field-service businesses
In active development Commercial project
Architecture decision
Small firms rarely fail for lack of customer records; they fail because a quote takes three days. So the centre of the system is not the contact — it is the quote. Voice note from the phone, AI draft, human approval, PDF. A memory of materials, prices and suppliers grows with every job. Tenant isolation, RBAC and audit logging are hard security boundaries, not options.
My role
Product concept, modular architecture, data model, worker design. Prepared for conversion into a SaaS product.

AI Marketing Studio
In active development Commercial project
Architecture decision
The central rule lives in the code, not in the manual: the AI produces drafts only; without human approval there is no export. Every generation, approval and export is written to the audit log. The AI adapter is provider-agnostic — with no API key it falls back to a mock, which makes tests possible without network and without cost. The test suite runs PGlite in-process, so no live database is needed.
My role
Concept, security boundaries, job-queue architecture, test strategy.

Youth AI Platform
A governance platform for municipalities
In active development Private repository
Architecture decision
Two data worlds in one database: geography via PostGIS, semantic similarity via pgvector. That lets hundreds of submissions be grouped by place and by meaning at once — "three streets over, twelve young people are saying the same thing in different words". The AI classifies, summarises and raises early warnings; it decides nothing. That boundary is the project's most important requirement, not its limitation.
My role
Concept, data model, governance rules, map integration. It grew out of my work on the Youth Executive Committee of Çankaya municipality.

Shopping-Centre Showcase
Running Client project
Architecture decision
Building a website is the smaller half; running it for years is the larger one. So the project ships automated checks for backup freshness, storage health, DNS hygiene and audit-log pruning — plus smoke tests and a written runbook. Staging deploys automatically; production only on explicit approval.
My role
Monorepo structure, CI/CD pipelines, operational automation, documentation.

Vitrinali
Running Commercial project
Architecture decision
For antiques and one-off items a shopping cart is the wrong metaphor — every sale starts with a conversation. So: static export, no payment provider, no session handling. Locally everything runs without Docker, Postgres or cloud storage (SQLite plus the filesystem); in production the same application runs on PostgreSQL and object storage. One data model, two environments, one build step.
My role
Architecture, environment-aware adapters, build pipeline, unit tests.
