About

Senior Backend & Platform Engineer with 6+ years of experience building distributed systems, internal platforms, and backend infrastructure serving millions of users. I enjoy designing systems that become foundational to a company's engineering stack—identity platforms, orchestration engines, search infrastructure, rule engines, and AI-powered backend services. My focus is on building scalable, loosely coupled architectures that simplify complex business workflows while improving reliability, performance, and developer productivity. At Loop Health, I built the company's centralized identity platform for 1.3M+ members, a real-time multi-partner orchestration engine that increased daily bookings by over 150%, a configurable eligibility platform used across business verticals, an Elasticsearch-powered discovery platform that reduced operational overhead dramatically, and an AI-driven care plan engine that has processed more than 1M biomarkers. Previously at MediBuddy, I built authentication and profile management systems serving over 2.5M users, improving login success rates, reducing operational escalations, and enabling seamless multi-profile experiences. My core areas of interest include: • Distributed systems & platform engineering • Backend architecture & system design • Identity & authentication platforms • Search & data-intensive systems • Event-driven architectures • Reliability engineering & observability • API platform design • Performance optimization at scale Technically, I work primarily with Node.js (NestJS & Express), PostgreSQL, Redis, Elasticsearch, Kafka, AWS, and modern cloud-native architectures.
