About

Backend Engineer owning distributed production systems at scale — across global payroll SaaS and high-volume e-commerce — from High-Level Design and API strategy to production reliability and observability. I specialize in building systems that stay correct under failure, scale horizontally without re-architecture, and remain maintainable as complexity grows. A few things I've shipped: → Re-architected a synchronous onboarding workflow into async event-driven orchestration — cutting activation time from 7 days to under 5 hours → Built an AI-powered document verification pipeline processing 600K+ documents/month — reducing manual review effort by 80% → Engineered a metadata-driven compliance rule engine — reducing rollout cycles from 2 weeks to same-day across 100+ country configurations → Redesigned an order fulfillment backend handling 50K+ daily orders as a Kafka-based async pipeline — improving throughput by 25%. Technical depth I bring: → Event-Driven Architecture — Kafka, RabbitMQ, SQS/SNS, async orchestration → Distributed Systems — Saga pattern, CQRS, idempotency, circuit breakers → Data Layer — PostgreSQL, MongoDB, Redis (caching), Elasticsearch (search) → Cloud & Infra — AWS (Bedrock, EC2, S3, Lambda, RDS), Docker, Kubernetes → Observability — Prometheus, Grafana, distributed tracing, p99 latency analysis → Core — Java 17, Spring Boot, Spring Security, Hibernate, gRPC

Work experience

Software Development Engineer 2 at Papaya Global, Apr 2025 - Present · 1 yr 5 mos, Bengaluru · Hybrid, - Worker Onboarding Re-Architecture: A tightly coupled synchronous onboarding workflow across 100+ country configurations was taking 7 days and failing silently under partial outages. Re-architected it as an async event-driven orchestration system using RabbitMQ and SQS with idempotent, fault-tolerant processing — cutting activation time to under 5 hours and eliminating duplicate operations under retries. - AI-Powered Document Verification (AWS Bedrock): Manual review of 600K+ documents/month was a 48-hour bottleneck with high error rates. Designed and owned the full pipeline — multi-source ingestion, document parsing, Bedrock integration, error handling, and DLQ recovery — cutting processing time to under 6 hours and reducing manual review effort by 80%. - Resilience Across Downstream Integrations: Cascading failures from vendor outages were propagating through core APIs. Introduced circuit breakers, retries, and DLQs via Resilience4j — reduced failure propagation by 40% and sustained graceful degradation under peak load. - Engineering Leadership: Ran weekly design reviews, mentored junior engineers, and authored event-driven architecture guidelines adopted as the team standard.

Software Development Engineer 1 at Papaya Global, Apr 2024 - Mar 2025 · 1 yr, Bengaluru · Hybrid, - EOR Update Automation: Architected a microservice for Employer of Record updates, automating multi-step approval workflows — cutting processing time by 50% and reducing cycle time from 10 days to 2 days. - Compliance & Leave Rule Engine: Rule changes across 100+ country configurations required a 2-week engineering cycle. Built a metadata-driven engine using PostgreSQL JSON schemas and MongoDB enabling self-serve rule deployment — reducing rollout time from 2 weeks to same-day. - RBAC & PII Security: Designed and enforced fine-grained Role-Based Access Control over PII and financial data using Spring Security — achieved 100% compliance across all security audits.

Software Developer at Industrybuying.com, Aug 2022 - Mar 2024 · 1 yr 8 mos, On-site, - Order Management System: Owned the full OMS backend across 6 microservices — inventory, fulfillment, and return workflows for 50K+ daily orders. Redesigned order fulfillment as a Kafka-based async pub/sub pipeline, improving throughput by 25% and reducing manual intervention by 35%. - Elasticsearch Catalog Search: Slow keyword search on a 100K+ SKU catalog was hurting conversion across 3 buyer-facing surfaces. Re-engineered indexing with fuzzy search and custom ranking strategies — reduced query latency by 40% and increased user engagement by 12%. - Redis Multi-Layer Caching: Catalog updates were bottlenecked on synchronous DB writes causing 2-day propagation delays at 500K+ daily reads. Introduced cache-aside patterns with TTL and async propagation — compressed update cycles to under 6 hours and cut DB load by 60%. - GraphQL for Internal Dashboards: Replaced bloated REST endpoints with GraphQL across 4 internal dashboards — reduced payload size by 40% and accelerated frontend developer velocity.

Software Developer Intern at Industrybuying.com, Aug 2021 - Jul 2022 · 1 yr, Remote, - Built and maintained microservices using Java, Spring Boot, Hibernate, and RabbitMQ — contributing across full SDLC from system design to test cycles. - Owned backend modules for catalog and order workflows, laying the foundation for features later scaled in the full-time role.
