Skills

The stack I use most often

The strongest part of my profile is still Java and Spring-based backend work. Around that, there is usually a lot of API design, integration work, delivery automation, and production support.

Java and Spring backend

This is still the strongest part of my profile: building services, integrations, and business logic in Java and the Spring ecosystem.

Microservices and architecture

I am comfortable with service decomposition, integration-heavy systems, and the practical side of architecture work.

API design and security

A lot of my work has involved secure interfaces and platform-level thinking rather than only internal service code.

Data, messaging, and persistence

I have worked across relational and non-relational stores, event flows, and the usual persistence concerns that come with enterprise products.

Cloud and delivery

Part of the job has often been making builds and deployments dependable, not only writing the feature code.

AI and frontend support

Backend work is the main strength, but I can also work with web UI and newer AI tooling when the project needs a complete solution.

How I use this stack

Technical depth plus delivery judgment

The most useful part of this skill set is not the number of tools. It is knowing where to keep things simple, where to be careful, and how to make decisions that still make sense six months later.

That same thinking is what I’m bringing into AI-related work as well. I’m interested in AI when it fits the product and can be supported properly, not just because it sounds new.
