What I'm looking for

I am looking for senior backend or architecture roles where I can modernize systems, design scalable microservices, and mentor teams in a collaborative, delivery-focused environment.

I am a senior software developer with deep experience designing and delivering web applications and backend systems across banking, insurance, government and fintech domains. I have led architecture and development efforts, migrating monolithic systems to microservices and implementing RESTful integrations for external partners.

My hands-on background spans full lifecycle development—building features, maintaining legacy monoliths, and creating new services using Java, Spring, and messaging platforms. I have implemented integrations for external integrators and delivered enterprise-grade applications for claims, lottery, postal administration, and blockchain-related projects.

I have managed and mentored small teams as a team leader and served as a software architect for large government and corporate projects. I have provided training on Java RMI, Spring, and JavaScript frameworks to government and bank developers, and I hold an Oracle Certified Professional, Java SE 6 Programmer certification.

I seek roles where I can apply proven architecture and backend engineering skills to modernize systems, drive reliable integrations, and mentor teams to deliver scalable, maintainable software.
