Hi, I'm Taha Çeken

Tech Lead · Full-Stack Engineer

I design scalable systems, build full-stack products, and help engineering teams turn complex requirements into reliable software.

About me

  • 💻 I have been coding for 7 years, including 3 years of full-time professional experience.
  • 🧭 As a Tech Lead, I guide technical direction, system architecture, engineering standards, and delivery.
  • 🛠️ I build end-to-end products with React / Vue, Node.js / NestJS, and Python / Django.
  • 🧩 I enjoy designing distributed systems, monorepos, shared UI systems, and reusable application foundations.
  • ☁️ I work with managed platforms and cloud services including AWS, Amplify, Convex, and Firebase.
  • 🇹🇷 Based in Türkiye and open to collaborating on meaningful web products.

What I bring as a Tech Lead

  • Translate business needs into scalable system designs, technical plans, and clear delivery paths.
  • Create architecture, system, sequence, and integration diagrams to make complex flows understandable.
  • Evaluate trade-offs across frontend, backend, data, cloud services, performance, and maintainability.
  • Establish engineering standards through code reviews, reusable patterns, testing practices, and technical documentation.
  • Mentor developers, distribute ownership, remove technical blockers, and keep teams aligned.
  • Identify technical risk and debt early while balancing long-term architecture with product delivery.

Workflow orchestration & authorization

  • Design durable, long-running workflows with retries, timeouts, idempotency, compensation, observability, and failure recovery in mind.
  • Build workflow orchestration and automation solutions with Temporal, Conductor OSS, and n8n.
  • Design authorization models using RBAC, ABAC, and ReBAC, choosing the right approach for the domain instead of forcing a single model everywhere.
  • Work with centralized policy and permission systems such as Permit.io, AWS Verified Permissions, and Cerbos.
  • Model resources, actions, relationships, and contextual attributes while keeping permission checks consistent across frontend and backend boundaries.

AI-assisted engineering

  • Use Claude Code and OpenAI Codex as part of the engineering workflow for planning, implementation, debugging, refactoring, code review, testing, and documentation.
  • Design reusable skills, agentic workflows, and scheduled automations that reduce repetitive work and improve engineering throughput.
  • Apply prompt engineering through clear context, constraints, examples, task decomposition, and explicit verification criteria.
  • Build human-in-the-loop workflows where AI accelerates delivery while technical decisions and output quality remain reviewable.
  • Turn recurring engineering practices into repeatable AI-assisted processes instead of relying on one-off prompts.
