About

I’m a Backend Software Engineer (SDE II) with 3+ years of experience building scalable, distributed backend systems in FinTech and AI/GenAI integrations. My core strength is end-to-end ownership of low-level design (LLD)—turning ambiguous requirements into clean APIs, solid data models, reliable async workflows, and production-grade services. I also contribute to high-level design (HLD) for distributed systems, focusing on scalability, fault tolerance, and operability. What I bring to teams: • System Design (HLD/LLD): microservices, distributed systems, API design, data modeling, concurrency, idempotency, caching, rate limiting • Reliability & Scale: performance tuning, capacity thinking, incident-driven hardening, zero-downtime changes, strong observability (metrics/logs/traces) • Backend Engineering: Java/Spring Boot, AWS, Kafka, MySQL; clean architecture and testable code • AI/Platform Integrations: LLM/agent workflows and enterprise integrations that improve automation and developer productivity I’m also strong in problem solving with 800+ DSA problems solved (Top 16% on LeetCode, peak contest rank ~350), which I apply to designing robust systems and debugging complex production issues. I enjoy roles where I can own designs, build reliable services, and solve scale + performance problems. Open to connecting with engineers and recruiters hiring for Backend/Platform, Distributed Systems, FinTech, and AI-integrations roles.
