Full-Stack Engineer (.NET/React/Node.js) building secure, multi-tenant SaaS platforms | Open to full-stack roles

About

I'm Karthik, a full-stack engineer who started in enterprise .NET (ASP.NET Core, C#, SQL Server) and spent the last year rebuilding my stack around React, Next.js, Node.js and PostgreSQL — because the problems worth solving today live in modern SaaS, not just legacy systems. What I actually do: 🔹 Currently building an HRMS (Human Resource Management System) using .NET at Natural Group — owning it from architecture through deployment. 🔹 Building an offline-first stock audit app for a CA firm — Expo/React Native frontend, Node.js + Prisma + PostgreSQL backend, S3 image storage, Bull MQ for background jobs — built to work reliably in warehouses with zero signal. 🔹 Comfortable owning a project end-to-end: requirements, system design, multi-tenant data architecture, secure REST APIs, and deployment — not just the parts in between. I hold an MCA from Manipal Institute of Technology, and I'm most useful on projects where "secure," "scalable," and "shipped on time" all have to be true at once — not just two out of three. Outside client work, I build small creative web projects — animation-heavy, interactive sites — just to stay sharp on frontend craft. 📩 Hiring for full-stack / SaaS engineering roles, or have a project that needs someone who can own architecture through delivery? Let's talk — message me here.
