Backend Engineer focused on scalable systems, clean architecture, and long-term maintainability.

For over 18 years, I’ve worked through different generations of backend development — from early PHP stacks to enterprise Java ecosystems and modern .NET architecture.

Today, my main focus is building reliable services in C#, designing systems that remain understandable under growth, pressure, and time.

I care less about trends and more about decisions that survive production.

• Simplify without sacrificing flexibility
• Let code document itself: readability is maintenance
• Align software decisions with business objectives
• Measure before optimizing: data guides decisions
• Design systems that scale without becoming incomprehensible

These are the languages and platforms I work with most often:

• Languages: C#, Java, PHP, TypeScript / JavaScript
• Frameworks & runtimes: .NET / ASP.NET Core, Spring Boot, Laravel, Node.js
• ORMs & databases: Entity Framework, Dapper, Prisma, Eloquent, Doctrine, SQL Server, PostgreSQL
• Communication: REST, GraphQL, gRPC, WebSockets
• Cloud & infrastructure: Azure, AWS, GCP, Docker, Kubernetes

I also have strong experience with clean architecture, distributed systems, performance optimization, and legacy code that still needs to run tomorrow.

Frameworks change.
Trends pass.
Clarity survives.

To me, maturity in software engineering is not a collection of libraries — it’s the judgment to know when not to use them.

Open to conversations about architecture, performance, distributed systems, and software that needs to survive reality.
