I design distributed backends and own the infrastructure they run on — from architecture through production operations. Three years in, currently the lead backend & infrastructure engineer at a D2C commerce-analytics startup.

• 🤖 Built & published a multi-tenant MCP server, live in the Claude connectors directory — lets customers query their entire marketplace business in plain English through Claude. Three independent layers of tenant isolation: Keycloak OAuth 2.0 / JWT → per-tenant Trino credentials → row-level security.
• ⚡ Built the “Promise Engine” — a storefront-agnostic delivery-date API — 6M+ monthly requests, currently powering Shopify product pages and checkout, configurable per client via pincode serviceability rules, facility mapping and SKU mapping. Two paths: product pages from a 10-minute inventory cache (no upstream calls), checkout against live WMS inventory. Cascades across multiple WMS platforms and facilities, maps storefront SKUs into warehouse namespaces (not 1:1), and decomposes combo SKUs absent from the WMS for live fan-out and reassembly.
• 🧠 Authored a 95-model semantic layer over Trino, unifying six marketplaces, a WMS and courier data into one queryable business model — with dashboards-as-a-service (stale-while-revalidate caching, background warmers, tiered per-tenant quotas).
• 🔌 Standardized a framework across 38+ third-party systems — marketplaces (Amazon SP-API & Vendor, Flipkart, Myntra), quick-commerce, 15+ courier APIs, and ad platforms — including resilient headless-browser automation (Playwright/Puppeteer, anti-bot evasion, self-healing BullMQ pipelines) for non-API sources.
• 🚀 Sole owner of the production estate — self-hosted observability (Grafana · Loki · Vector · Prometheus) at 2,000+ logs/sec and 80% lower cost than Datadog, Docker, nginx/Let's Encrypt, zero-downtime deploys, and a Zero Trust Tailscale network with no public SSH.
• 💰 Cost engineering — cut $12,000/year by migrating Airbyte off Kubernetes (EKS) to a single-node abctl deployment, and eliminated production replication lag by tuning AWS DMS CDC pipelines (Postgres → Redshift).

• Omnivio Lens — hosted multi-tenant MCP server for marketplace analytics, published in the Claude connectors directory.
• Portfolio — selected work & background.
• ✍️ I write about backend architecture, MCP and infrastructure on Dev.to.

Full-time Linux user and unapologetic tinkerer — I daily-drive Fedora and enjoy taming hardware, the kernel, and the desktop as much as I enjoy backend systems.
