About 01
"I came in to write code.
I ended up rebuilding everything."

I joined BricklyGlobal as a backend developer — fresh out of university, ready to ship features. Then the company's cloud costs spiraled and the infrastructure needed a complete rethink. There was no senior DevOps engineer. There was just me.

I took full ownership. Rebuilt the AWS architecture from scratch. Cut monthly costs from ₹1,30,000 to ₹8,000 — a 94% reduction — while setting up CI/CD pipelines, monitoring dashboards, and production server management. All while continuing to build product features and co-creating BRIKI — our IoT platform now running in multiple enterprise client locations.

What
I Build

Four domains. One engineer. Full-stack ownership from bare metal infrastructure to user-facing product.

01

Cloud Infrastructure & DevOps

Architects, deploys, and maintains the entire cloud ecosystem. From provisioning servers to configuring CI/CD, monitoring, and zero-downtime deployments — sole owner, full accountability.

02

Backend Development & API Engineering

Designs and implements high-performance APIs and backend systems. RESTful services, async task queues, database architecture — built for reliability and scale from day one.

IoT Product Engineering

Co-created BRIKI from scratch — a full IoT platform for smart device management. Hardware integration, session management, multi-location dashboards. Zero to enterprise clients.

System Architecture & R&D

Evaluates, designs, and evolves system architecture to meet growing product demands. Observability-first with Prometheus and Grafana. Proactive performance engineering before problems arise.

Projects

01

BRIKI — IoT Massage Chair Platform

Led the complete design, architecture, and implementation of a B2B IoT platform for smart massage chair management. Integrated Tuya hardware SDK, built session management, multi-location admin dashboards, and scaled from pilot to enterprise clients across multiple sites. Zero to production — one engineer, end to end.

03

Full-Stack Product Development

Designs and ships backend APIs (Django, FastAPI), database systems (PostgreSQL, Firestore), and frontend interfaces using AI-accelerated workflows. Moves fast without sacrificing quality — building the product features that users actually touch, while maintaining the infrastructure they depend on.
