What I'm looking for

I’m looking for roles where I build and modernize Java/Spring backend systems, own production support and deployments (SIT/UAT), and collaborate with teams to deliver reliable web apps—plus space to explore Java blockchain smart contracts and agentic AI.

I’m a Senior Java Developer focused on building web applications and providing strong technical support in production environments. I’ve worked on the transformation/modernization of a client’s back-office using Java and Spring, with hands-on ownership of fixes, documentation, and deployments.

Across multiple projects, I supported issues raised by teams, handled production fixes, and participated in deployment to SIT & UAT. I’ve delivered feature work with SIT testing and collaborated with clients to gather requirements and define solutions.

I’m also interested in Java blockchain development—like developing smart contracts and deploying to a mainnet. Alongside my core Java background, I bring experience with full web stacks and tooling such as NodeJS/AngularJS, databases (Oracle SQL, MSSQL, MySQL, MongoDB), and containerized environments (Docker, Linux), plus continuous learning through AI-related courses.
