Product engineer · Istanbul

I build digital products from the interface to the system behind it.

I work across product UX, frontend, backend, relational data, operational tools, and measurement. My projects range from travel commerce and booking systems to local-service operations and vertical e-commerce.

Open to Product Engineer and Full-Stack Product Engineer roles, especially on frequently used, international products.

Selected work

Four products worth opening.

Public interfaces, dated production evidence, and the decisions behind each system. Private customer and operator data stay out.

Evidence policy

Transparent, without turning the portfolio into a dashboard.

Production figures are dated observations from GA4 and Google Search Console. “AI referral sessions” means visits GA4 observed from assistants such as ChatGPT or Gemini. It does not represent every citation, assisted decision, sale, or a causal lift from one change.

How I work

Own the complete loop.

I am most useful where product judgment, engineering, and growth meet.

01

Product

Turn an ambiguous business problem into a clear customer journey, a small set of decisions, and a product people can actually use.

02

Engineering

Connect the interface to backend rules, relational data, payments, documents, messaging, and the operator workflow behind the screen.

03

Growth

Instrument the product, study search and production behaviour, find the bottleneck, and improve the next measurable outcome.

About

I started in frontend. The work kept expanding.

I started my career in frontend engineering and have 4.5 years of professional experience shipping customer-facing products with React, Next.js, TypeScript, Vue, and Nuxt.

In March 2025, I designed and launched Kings World Transfer as my first end-to-end product. What began as a booking interface grew into a production system spanning pricing, reservation and payment state, PostgreSQL data, transactional email, generated documents, analytics, deployment, and operator handoff.

Since then, I have built and operated owned and client products across travel, automotive, hospitality, and local commerce. I began this work alongside my full-time frontend role; since January 2026 it has been my primary focus. I work directly with operators, turn ambiguous business needs into reliable product flows, and use production behaviour, search demand, and customer signals to decide what to improve next.

My frontend roots still shape how I work, but I now own the full loop: interface quality, domain and state modelling, backend rules, relational data, integrations, background jobs, failure handling, measurement, and ongoing operations. Earlier work in crypto markets and Web3 sharpened how I think about incentives, irreversible state, and risk.

I am looking for a high-ownership Product Engineer role where I can stay close to users, ship across the stack, and improve one product over time. I am based in Istanbul; outside work I enjoy training, long drives, and browser-based strategy and board games.
