Message

At Zunabet, I developed and maintained casino and sportsbook features across player accounts, wallets, payments, and promotions. I also worked on SOFTSWISS integration workflows, including provider launch flows, APIs, callbacks, and back-office configuration.

I built and supported Java/Spring Boot services and Angular/TypeScript interfaces, and strengthened production reliability through Docker/Kubernetes deployments, CI/CD checks, logging, and monitoring. Alongside development, I performed QA across payment flows, authentication, mobile regression, and release verification.

Across roles at Oppy Technologies, Imobisoft, Kalida Technologies, Napsen Inc., and ABM Software Ltd, I delivered SaaS features, cloud applications, customer portals, APIs, and integrations. My work has included React and Next.js, Node.js and TypeScript, Python, C#/.NET, relational databases, and automated testing.
