Senior Software Engineer & Consultant
I design, build, and modernize software.
I am a full-stack software engineer and software architect in Ankara, Türkiye, seventeen years into designing, building and modernizing software for airlines, banks and regulated platforms. With what the tooling can do now, one senior engineer is enough to build an entire system, end to end: frontend and backend development, system architecture, optimization, UX and visual design, and project delivery. I work across disciplines to take software from early ideas to production, and to improve mature products already serving real users.

What I can help you with
What do I get hired to do?
Eight kinds of engagement: product build end to end, rescue and modernization, frontend architecture and performance, backend performance and scalability, technical leadership and advisory, AI-assisted engineering, UX and visual design, and architecture review. Most projects are a combination, so tell me the problem and I'll tell you which of these it actually is.
01
Full-Stack Development
Node.js services, GraphQL and REST APIs, databases, integrations, authentication and cloud deployment behind the interface.
02
Software Architecture
System design, technology selection and the cross-cutting concerns: security, caching, logging and error handling, written down so a team can build against them.
03
Digital Transformation
Manual, paper and spreadsheet-driven processes turned into software a team will actually use: documents, approvals, tracking and reporting.
04
Application Modernization
Moving mature applications toward current architecture in gradual, shippable steps instead of a big-bang rewrite.
05
Product Engineering
Production-ready web products from concept through implementation and delivery, with someone accountable for the whole path.
06
Frontend Engineering
React and TypeScript architecture, complex interfaces, state management, performance, testing and long-term maintainability.
07
AI Integration
Agents, retrieval and automation built into a product where they solve a real problem, and left out where they don't.
08
Project Workflow Management
Scope breakdown, estimation, delivery cadence, code review and release process, so progress and risk stay visible to everyone, not only the engineers.
09
UX/VD Design
Interface architecture, interaction and visual design, working alongside your designers or on my own when a project doesn't have one.

Business Analysis
Turning domain rules and requirements into something buildable, and asking the questions that need answering before any of it becomes code.
What people say
Referrals from people I've worked with.
One of the strongest developers I’ve had the opportunity to work with. Beyond being technically excellent, what I appreciate most is his ability to understand the business and identify what the product truly needs. He doesn’t simply develop what’s in front of him; he questions why it’s being built, contributes his perspective at the right moments, and shapes technical decisions around the broader business goals. This mindset makes working with him genuinely valuable.
Oğuz Güç
Founder, Atölye15
Emin brings a rare combination of engineering depth and product awareness. He doesn't only think about whether something works, but whether it is maintainable and appropriate for the product.
Mustafa Erşahin
VP of R&D, Commencis
Emin quickly found his feet within an established team and a complex software product, and took on independent responsibility in a remarkably short space of time. He consistently delivered outstanding results and made a significant contribution to the technical restructuring of our document management and file storage systems. Emin is an extremely capable, reliable and proactive developer, and I am convinced that he will continue to make a strong impression wherever his career takes him in the future. I would be delighted to recommend him and look forward to following his continued development and success.
Robin Kroh
Senior Product Owner, Heinrich Schmid
I had the pleasure of working with Emin for several years, and I would happily recommend him. He brings extensive experience delivering software across a wide range of industries, including banking, airlines, and SaaS. Emin has a strong sense of ownership and takes the time to understand the technical details behind the problems he is solving, while also being an excellent communicator with both technical and non-technical stakeholders. Most importantly, he is someone you can rely on to consistently deliver high-quality results.
Kürşat Duygulu
Software Development Team Leader, Zeplin.io
I worked with Emin on the Pegasus project and took over some of his code. It didn’t take long for me to develop the mindset that, “If Emin wrote it, it must be right.” He takes real ownership of his work, consistently delivers clean, high-quality results, and is someone you can genuinely trust when working together.
Erman Tepe
Engineering Manager, Commencis
Emin was someone who consistently brought clarity to ambiguous problems, with a deep understanding of user needs and an ability to translate that across technical and product teams.

Verification-gated AI engineering
A methodology I founded, combining years of real-user project experience with a software-engineering education and current AI systems: explicit contracts, verification gates and review steps that keep generated code honest.
About
A Software Architect, bridging years of engineering experience with emerging technology.
I started in enterprise software, spent years on product engineering at Zeplin, led a frontend team at an airline, and built and maintained large systems for banks and construction. That mix is the point: I can reason about an interface, the service behind it, and the migration path between what exists and what should.
MSc in Software Engineering from METU, BSc in Computer Engineering from Başkent. Currently working with AI-assisted engineering: agents, retrieval and verification-gated workflows, where it earns its place in a product.
