01Profile

I have been writing software since 2021. For the past four years I have built — and owned as a product — the order, payment and integration infrastructure behind a 2-million-user B2C/C2C platform and a 1,000+ dealer B2B platform, with more than 30,000 orders flowing through it every month.

I have shipped Node.js and Next.js in production since 2022 and Laravel since 2024. I use Claude Code and OpenAI Codex as force multipliers, and keep architecture, code review and security decisions in my own hands.

Today I am CTO at itemgold, a marketplace for gaming products, building its B2B, B2C and C2C platforms and its AI-driven product features.

02Experience

CTO — itemgold

Took itemgold.com, a marketplace for gaming products, from idea to production in four months. Designed the architecture of its global B2B, B2C and C2C platforms from scratch.

I lead the engineering team and make architecture, infrastructure and roadmap decisions together with product, finance and marketing.

Built the quality stack from day one: Playwright E2E suites running nightly on the servers, Sentry and Grafana monitoring, and automatic error alerts to Telegram channels.

Systems I built

Score-based fraud system
Scores suspicious activity, triggers step-up verification automatically and suspends accounts when needed.
AI support assistant
An LLM-based chat bot that handles user requests in place of live support.
Agentic back office
An admin panel made of AI agents that run day-to-day operations.
AI product onboarding & pricing
Pipelines that process product data with AI, add it to the catalogue and keep prices updated automatically.
Analytics & pricing tools
Customer KPI tracking, competitor product and price analysis, global FX rate tracking.

Full-Stack Developer & Product Owner — Noxart Games

In a 15-person engineering team I built a 2-million-user B2C/C2C e-commerce platform and a 1,000+ dealer B2B platform end to end, and ran the order and payment infrastructure handling 30,000+ orders a month.

Integrated numerous payment providers for Turkey and global markets along with supplier APIs, and designed the REST API for the B2B dealer network.

Built edge-first infrastructure focused on performance and security with Cloudflare Workers, D1, Pages and WAF; worked across AWS, OVH and OpenStack.

Led two major data and system migrations to a new platform, including the move from Node.js to Laravel. From 2024 on, brought AI-assisted workflows into the team's development process.
