Backend Engineer building event-driven FinTech systems at scale.
I have 4+ years of experience designing distributed backend systems in Node.js and NestJS, with a focus on high-throughput, low-latency services powered by Apache Kafka and Redis. Currently at WebileApps (a KFintech company), where I build platforms for mutual funds, alternate investments, and portfolio management.
- Design and build event-driven microservices with NestJS, TypeScript, and Apache Kafka
- Engineer resilient financial flows (SIP auto-debit, unit allotment) with strict idempotency and Redis-based distributed locks
- Build client-agnostic GraphQL & REST APIs serving real-time investor and portfolio data
- Optimize database performance across PostgreSQL and MongoDB
- Instrument systems with Prometheus & Grafana for observability and faster incident resolution
FinTech / capital markets — mutual funds, RTA integrations, Alternate Investment Funds (AIF), and Portfolio Management Services (PMS) digital onboarding platforms for multiple AMCs.
- Cut API latency by 45%+ with advanced Redis caching for read spikes after EOD NAV declarations
- Reduced average DB query times by 35% via schema redesign and PostgreSQL/MongoDB query optimization
- Lowered production incident MTTR by 40% through real-time Prometheus/Grafana dashboards
- Built a zero-duplicate-allotment SIP auto-debit system that holds up during peak monthly transaction windows
- Mentored and trained interns, and served as backend PR gatekeeper to keep tech debt near zero
