About

I am a Senior Backend Engineer and Technical Lead with nearly 7 years of experience designing, building, and scaling distributed systems, cloud-native microservices, and high-throughput backend platforms. Currently, as a Technical Lead at Zact, I drive the architecture of a centralized, event-driven notification platform (Email, SMS, Push) and statement generation workflows. I utilize Kafka, Quartz Scheduler, and the Transactional Outbox pattern with Dead Letter Queues to guarantee reliable asynchronous processing across the organization. Previously at VerSe Innovation, I scaled the wallet and payment infrastructure for the Josh platform, managing 1Cr+ daily encrypted transactions and handling peak throughputs exceeding 1,200 TPS. My focus has consistently been on deep system reliability and optimization—from resolving complex database concurrency issues (migrating from pessimistic to optimistic locking) to implementing Bloom Filters that eliminated ~99% of unnecessary database existence checks. Core Technical Expertise: ► Languages & Frameworks: Java, Spring Boot, Spring Cloud, Hibernate, REST APIs ► Architecture: Microservices, Event-Driven Architecture, CQRS, Saga Pattern, Database Concurrency ► Databases & Caching: PostgreSQL, Redis, Elasticsearch, Oracle, MongoDB ► Cloud & Infrastructure: AWS, GCP, Kubernetes, Docker, Kafka, RabbitMQ, CI/CD ► Observability: Distributed Tracing, Grafana, Prometheus, Thread Dump & Query Plan Analysis I am passionate about tackling zero-to-one engineering challenges, designing resilient system architectures, and mentoring teams to deliver seamless, highly available enterprise solutions.
