About

I’m a Backend Engineer with 3.5 years of experience designing and building scalable, event-driven microservices using Java, Spring Boot, and Kafka. Currently working on a loyalty-based flight booking platform, I design distributed services that handle asynchronous workflows, external API integrations (GDS systems), failure retries, and transactional consistency across booking, payment, and reward flows. My core strengths include: • Designing event-driven architectures using Kafka • Implementing secure REST APIs with JWT/OAuth-based authentication • Handling concurrency and asynchronous processing in production systems • Optimizing database performance across MySQL, PostgreSQL & MongoDB • Improving system observability using Datadog dashboards, logs & alerts • Contributing to LLD/HLD discussions and clean microservice boundaries I enjoy solving distributed systems problems, improving reliability, and building resilient backend platforms that scale. Currently open to backend engineering roles in product companies and high-growth startups where system design, scalability, and clean architecture matter.

I’m a Backend Engineer with 3.5 years of experience building scalable distributed systems using Java, Spring Boot, Kafka, and AWS.
I contributed to building a loyalty-based flight booking and rewards platform from scratch, currently supporting 30K–50K+ booking and redemption transactions per week across enterprise clients, with peak traffic bursts of ~100 requests/second during high-demand windows.
Key areas of impact:
Designed and maintained 6+ production microservices with clear domain boundaries
Built secure REST APIs using JWT/OAuth-based authentication
Implemented event-driven workflows using Kafka for asynchronous booking & reward processing
Handled concurrency, retries, and idempotency in distributed transaction flows
Improved database performance across MySQL & PostgreSQL (~30–35% latency reduction)
Contributed to HLD/LLD discussions and scalable architecture decisions
I enjoy solving reliability challenges, reducing bottlenecks, and building backend systems that scale predictably under production load.
Currently open to backend engineering roles where system design, scalability, and clean architecture matter.
