Shivansh Tiwari
Software Engineer / Full Stack Architect

Building systems with the curiosity that started it all.

As a kid, I opened up my CPU just to understand what was happening inside. Engineering made me fall in love with low-level languages and the elegance behind how machines really work. Today, in the era of agentic engineering, I get to turn that same curiosity into scalable products, AI workflows, and production systems.

About

I care about systems that are simple to use and hard to break.

I am a full-stack software engineer focused on scalable backend systems, real-time applications, and polished product interfaces. My work sits at the intersection of practical architecture, product clarity, and reliable execution.

Backend platforms

APIs, data models, queues, caching, and services designed for reliability under real usage.

Product engineering

End-to-end delivery across Next.js, React, TypeScript, Node.js, Go, PostgreSQL, and Redis.

AI integrations

Practical LLM features, moderation flows, conversational products, and automation around user workflows.

What I work on

Product-minded engineering across the stack.

The portfolio is centered on shipped systems, practical architecture, and implementation work that moves from idea to production.

Full-stack products

Building complete product surfaces with thoughtful UI, secure APIs, authentication, and maintainable data layers.

Backend architecture

Designing Node.js and Go services with PostgreSQL, Redis, queues, clean boundaries, and observability in mind.

Real-time workflows

Shipping collaborative, live, and event-driven features using WebSockets, Kafka, and fast state propagation.

Delivery systems

Improving release confidence with Dockerized services, CI/CD automation, and deployment-ready project structure.

Experience

Work across backend, product, platform, and mentoring.
