I design systems, write the code, and treat software as something worth crafting.

Backend at heart — Node.js, NestJS and TypeScript — wiring services together with gRPC and RabbitMQ, keeping things live over WebSocket, and shipping the React frontend on top. All the way to AWS, and all the way to the store.

I'm a full-stack engineer with around two years of professional experience, most of it spent in the backend. I like the parts other people find tedious — schema design, message queues, retries, the contract between two services — because that's where reliability actually lives.

I graduated from Çanakkale Onsekiz Mart University in Computer Engineering (2025), and I also build my own products — two AI-powered apps, designed and shipped solo from the database to the store listing. Owning something end to end is the fastest way I know to become a better engineer.

Software Engineer / Technical Project Coordinator

Senior technical role at Meyer Group — a 145-year-old identification and security technology company (Turkish Airlines and Koç Holding among its customers). Owned the technical software applications side end to end, from infrastructure setup to stable production operation.

• Configured and set up project infrastructure, managing deployment pipelines and go-live processes through to stable production.
• Evaluated system architecture and infrastructure to determine optimal implementation strategies for client requirements.
• Translated business and technical needs into actionable specifications — SRS, user scenarios, workflows.
• Coordinated cross-functional development, test and support teams through sprint planning and backlog prioritization.

Backend Developer

Joined a 5-person engineering team rebuilding a B2B fintech super-app. The role covered the bulk of the systems I work with today — almost everything I know about backend in production, I learned here.

• Microservice migration — re-architected the platform from a modular monolith into 4 gRPC-based services with RabbitMQ messaging, gaining deployment independence and fault isolation between domains.
• Real-time communication — built WebSocket-based live-chat and a voice-call service end to end across the NestJS backend and React frontend.
• APIs & frontends — designed REST and GraphQL endpoints and shipped type-safe React + TypeScript admin panels with Redux and performance optimizations on top.
• Cloud & CI/CD — provisioned AWS infrastructure (EC2, S3, DynamoDB, Lambda, Cognito), containerized services with Docker, and contributed to CI/CD pipelines.
• Reliability & performance — set up Prometheus + Grafana dashboards for monitoring, and built distributed Redis caching strategies that materially cut database response times.

Independent Developer

Designed, built and shipped two AI-powered mobile apps to Google Play — IsimAI and Pingsight — entirely solo, from data model and backend to UI and store listing.

IsimAI

Personalized baby names, generated by AI.

Thousands of baby names is an overwhelming problem. IsimAI turns a few prompts into a short list that actually fits — personalized suggestions powered by GPT. Designed, built and published end to end as the sole developer.

Pingsight

See your network through the eyes of AI.

Scans the Wi-Fi you're connected to, discovers every device on it, and runs an AI security analysis to surface what's exposed. A network scanner that actually explains itself.
