About Aswin S

Hey, I\'m a backend engineer at Retainful, where we\'re building some seriously cool stuff — think high-scale SaaS, real-time event pipelines, and email systems that can blast out a million+ messages in under 20 minutes (yep, we move fast).Most of my day-to-day is deep in the weeds with NestJS, BullMQ, PostgreSQL, ClickHouse, and all the good stuff that makes modern apps tick. I’m big on: Architecting event-driven systems that are clean, scalable, and don’t fall apart under pressure Owning everything from multi-tenant infra to Shopify/WooCommerce integrations Writing cron jobs, queue workers, and backend flows that just… work (no drama)I’m all about building smart, async-first systems that run smooth and stay out of the way. If you’re into backend magic, webhooks, queues, or scaling problems — we’ll get along just fine.Let’s connect if you:Love talking backend architecture, SaaS infra, or custom analyticsAre hacking on something that needs to scale big without melting downWanna vibe over clean code, system design, or tech that actually solves problems
