About

Most backend bugs don't come from bad code. They come from business logic that was never truly understood. I'm a Java backend developer with 3 years building financial systems specifically in microfinance and loan management where the logic is complex, the data is critical, and failures cost real money. I build at VolkSoft, where I own backend services processing 1,000+ daily loan disbursements. What I actually work on: • REST API design and optimization (Spring Boot, Hibernate, MySQL) • Business logic for loan processing, customer workflows, and transaction validation • Debugging production issues and reducing failure rates across financial pipelines • Microservices architecture: API Gateway, service discovery, inter-service communication •Security implementation with JWT and Spring Security A few numbers that matter: • 20% improvement in API response time across core loan disbursement services • 25% reduction in API failure rate through targeted refactoring • 40% reduction in manual intervention through automated financial business logic • 95%+ on-time sprint delivery over 12+ months What makes me different: I come from an electrical engineering background which means I learned to debug complex systems before I wrote a single line of production code. I think in flows, failure states, and edge cases first. Currently: deepening my system design skills and expanding into distributed systems and cloud-native architecture. Looking for mid-level backend roles where I can work on product-grade systems with real scale and complexity. 📩 shyamtalagapu710@gmail.com | Open to opportunities
