What I'm looking for

I’m looking for a product-focused team where I can build reactive Java microservices and Android experiences, own end-to-end delivery, and work in Agile environments with strong CI/CD and observability.

I’m a Full Stack Developer with 7 years and 4 months of experience designing and delivering end-to-end software solutions. I build reliable backend systems with Java and Spring Boot, and I bring them to life with hands-on mobile development using Android (Java).

In recent roles, I’ve led development of high-throughput services and case lifecycle workflows, including reactive RESTful microservices with Spring Boot and Spring WebFlux. I’ve applied multi-tenant architecture patterns to support multiple client environments within a shared platform, and I’ve used Splunk for real-time monitoring and observability.

I’ve worked across fintech, e-commerce, and logistics, integrating third-party platforms like payment gateways and BNPL providers (Cashfree, Kredx, Rupifi) as well as shipping APIs (Shiprocket, DHL). I’ve also delivered Android client applications, including feature deployments, version updates, and crash monitoring on Google Play Store.

My approach is grounded in Agile and Scrum collaboration, with strong engineering practices around testing and delivery. I use Jenkins CI/CD, Flyway database migrations, and automated workflows to keep releases smooth, secure, and maintainable.
