Senior Software Engineer — Backend / Full Stack

I design and ship backends that stay calm under load — microservices in Go, real-time systems, and APIs that teams can actually evolve.

KashviGolang Framework

Author of a production-grade Go framework: CLI, ORM, auth, queues, docs — shipped as a real product, not a weekend repo.

A backend framework I built from the ground up for teams who want Go services with clean architecture, strong conventions, and room to grow. Think productivity without sacrificing structure.

About

Practical engineer, systems-first mindset

Short version: I like useful software that survives contact with production.

I’m a practical problem solver based in Delhi. Most of my time goes into backend architecture — how services talk, how data flows, and how systems stay maintainable when traffic and teams both scale up.

Go is my happy place: I lean on clean architecture and SOLID principles to keep boundaries clear. I’ve also shipped plenty of Node.js and PHP when the problem called for it, and I’m comfortable across MongoDB, PostgreSQL, and Redis — plus Kafka when the pipeline needs to be serious.

On the human side, I enjoy mentoring: breaking down complex ideas, reviewing with empathy, and helping juniors ship with confidence. Slightly desi, straight-talking, tech-first.

  • Strengths
  • Backend architecture & scalable system design
  • Go microservices (clean architecture, SOLID)
  • Real-time systems — notifications, tracking pipelines
  • REST APIs & distributed systems
  • CI/CD and AWS ECS in production

Kashvi Framework

My flagship product: a custom Go framework focused on scalability, modularity, and developer productivity — not a weekend toy, a deliberate platform for serious backends.

Why Kashvi is different →

E-Library REST API

A structured API layer with SOLID boundaries, PostgreSQL underneath, and patterns that make features easy to add without breaking callers.

GoPostgreSQLRESTSOLID

Real-time student tracking & parent notifications

Safety-critical flows: biometrics, face recognition hooks, and live tracking with alerting so parents and admins get signal, not noise.

Real-timeNotificationsDistributed systems

Multi-platform e-commerce backend

Centralized orders and inventory so multiple storefronts could share one source of truth without turning the database into a battlefield.

MicroservicesRESTPostgreSQL / Redis

Voice-based billing (experimental)

Exploring voice as an interface for SMEs — fast entry, fewer mistakes at the counter, and room to iterate on UX.
