Mansi Pandey
@mansipandey
Backend developer specializing in AI-powered automation and full-stack systems.
What I'm looking for
I build reliable backend systems that turn complex workflows into automated, measurable services. I’m currently taking complete ownership of a token generation service, optimizing Selenium automation to reduce token failures and captcha lockouts under high concurrency.
I also design observability into the product by building end-to-end alerting with Prometheus and Grafana, so I can surface latency, error rates, and availability across services. Beyond monitoring, I’ve built an LLM-driven browser automation agent that interprets login and verification flows to replace manual token generation.
Earlier, at SnapSage, I led backend development for a product review and rewards platform—building the Node.js/Express/TypeScript architecture, modeling data with Prisma and PostgreSQL, and implementing secure JWT auth with OTP verification and role-based admin access. I also integrated a generative AI layer to score review authenticity and speed up admin approvals.
Alongside production work, I enjoy shipping real-time AI experiences—like my Voice Language Coach that streams speech-to-text, LLM reasoning, and text-to-speech over WebSockets with structured feedback. My north star is pragmatic engineering: automation that works in the real world, with strong metrics and continuous iteration.
