About

As a backend developer focused on crafting production-grade systems, I’m passionate about writing code that scales, performs, and lasts. I specialize in Java and Spring Boot, building robust backend systems with microservices architecture, Kafka for real-time event streaming, and Docker for containerized deployments. My focus is on creating clean, modular, and efficient services that are easy to scale and maintain. Alongside backend development, I have hands-on experience with React.js for building intuitive and performant front-end interfaces — bridging the gap between backend logic and user experience. 🔧 Tech Stack: Java, Spring Boot, Microservices, Kafka, Docker, REST APIs, React.js, MongoDB, MySQL, JavaScript (ES6+), Tailwind CSS ⚙️ Interests: System design, distributed systems, clean architecture, and DevOps practices 📈 Always eager to learn, build, and collaborate on impactful software that solves real-world problems.

Built RESTful and reactive microservices using Spring Boot + WebFlux, delivering low-latency backend APIs for production use cases.
Developed trend & variance comparison APIs to analyze multi-category data over time, supporting accurate business insights.
Implemented a cache-first data layer using Redis + GZIP/Base64 compression, reducing repeated downstream service calls and improving response speed.
Integrated microservices using non-blocking WebFlux (Mono/WebClient) to improve concurrency and resource utilization.
Worked on data mapping and transformation using Jackson and functional Java to compute metrics and analyze variance across entities.
Built an intelligent conditional retrieval layer that enriches responses based on inferred data patterns, delivering more contextual outputs without additional service calls.
Improved backend resilience using custom exception handling, fallback logic, and graceful degradation during dependency failures.
Produced DFDs (Data Flow Diagrams) and API journey documentation outlining request flow, caching mechanisms, and fallback logic for clearer collaboration.
Participated in migrating legacy modules to modern Spring Boot + WebFlux-based services as part of backend modernization efforts.
Worked closely with frontend, QA, and product teams to define clean API contracts and deliver backend features aligned with product requirements.
Applied Jakarta validation, structured logging, and REST best practices, enhancing reliability and observability across services.
