About

Lead Software Engineer | Java · Python · Distributed Systems | 14+ Years I design and build large-scale distributed systems that handle millions of records, serve multiple regions, and stay reliable under production pressure. Over 14 years across product companies and enterprise platforms, I've worked across the full backend stack — Java Spring Boot, Python (Flask, FastAPI, Celery), microservices, Kafka-based event streaming, and AWS — shipping systems that teams depend on daily. A few things I've delivered: → Migrated 77M records across 7 channel types at 100K records/1.9s — zero customer impact → Architected a multi-region SaaS rollout across 30+ integrations for a Dubai compliance region → Designed a zero-downtime Elasticsearch → OpenSearch migration for a 6-year-old production search system → Built an LLM + vector search ticket triage prototype that leadership carried forward into product → Cut active feature flags by 50% in one month via a self-initiated Jenkins automation pipeline I operate at the intersection of backend engineering, platform reliability, and architecture — mentoring teams, leading design reviews, and owning production on-call for high-traffic systems. 📌 Skills: Java · Spring Boot · Python · Microservices · Apache Kafka · PostgreSQL · Redis · Elasticsearch · AWS · Docker · Kubernetes · System Design · REST APIs · CI/CD · Vector Databases · ETL · GDPR · Distributed Systems AWS Certified Solutions Architect – Associate
