Backend Engineer | Distributed Systems & Platform Engineering | Node.js · PostgreSQL · AWS | Multi-tenant SaaS at scale

About

I'm a backend engineer who takes products from first commit to production and owns them there. At my current company I built and scaled a multi-tenant B2B SaaS to a measured peak of 300K requests per minute, serving 40,000+ users, and I lead its engineering. I own the REST APIs, a webhook-driven idempotent pipeline (no duplicate writes, dead-letter recovery), PostgreSQL performance (indexing, replication, an 80% query-latency cut, and point-in-time recovery during a live incident), AWS infrastructure, and releases gated by tests in CI with SigNoz for observability. Before that I led full-stack delivery of multi-tenant SaaS across CRM, finance, and retail for 1,000+ users, and shipped a production ERP for MSME clients in under two months. I care about distributed systems, platform engineering, and resilient software at scale, and I integrate LLMs (OpenAI, Anthropic) into production by choice. I ship open-source too: Valid8r (a Node validation library on npm) and PRism (an AI PR assistant). Stack: Node.js, TypeScript, Java, Python · Express, REST, webhooks, event-driven · PostgreSQL, Redis, MongoDB · AWS, Docker, CI/CD · system design, multi-tenancy, RBAC.
