Backend engineer profile

Backend Engineer & Tech Lead

Backend engineer and tech lead building systems that scale, stay reliable, and survive real production complexity.

I build backend platforms, production systems, and internal infrastructure for teams that need scale, reliability, and clean execution.

Currently at Zepto. Previously led backend and platform work at Unacademy across CRM, authorization, observability, and infrastructure. My focus is distributed systems, platform engineering, and the technical decisions that keep systems usable under real operational load.

About

Backend engineering with ownership, architecture, and production thinking.

This section now does more than introduce you. It signals leadership, engineering maturity, and the system-design instincts that senior backend roles care about.

I work best where backend architecture, product scale, and engineering ownership intersect. My experience spans internal platforms, APIs, cloud infrastructure, and production reliability.

I’ve led teams, owned critical services, improved cost efficiency, and built systems that support real business operations rather than toy workloads.

What I optimize for is not just shipping features, but designing systems that stay understandable, observable, and maintainable as load and team complexity increase.

Tech Leadership

  • Led in-house CRM engineering work for large internal operations.
  • Owned backend and platform decisions across authorization, notifications, logging, and observability.
  • Worked closely with infrastructure and SRE concerns including secrets handling, monitoring, and reliability.
  • Built APIs and backend systems consumed by multiple clients without breaking product velocity.

What I Care About

  • Scalability over short-term hacks
  • Reliability and observability by default
  • Clear API contracts across teams
  • Cost-aware infrastructure decisions
  • Simple architectures that survive growth

Selected Work

Selected work with a little more engineering depth.

Instead of shallow project cards, this section now explains the problem, the architectural direction, and the outcome so it reads more like a senior engineer speaking about real systems.

Unacademy

Infrastructure cost optimization

Led efforts that reduced web services cloud cost by around 40% while improving scalability and infrastructure management.

Unacademy

Kubernetes migration

Planned and migrated core backend servers from standalone EC2 machines to Kubernetes clusters for better availability and scaling.

Unacademy

Authorization architecture

Architected the authorization management service for external and internal users across the wider Unacademy ecosystem.

Kruzr

Real-time stream processing

Implemented synchronized sensor-data processing pipelines with low latency to support quick intervention and behavior analysis.

Experience

Experience across backend development, platform engineering, and cloud infrastructure.

I replaced the abstract timeline with real roles and concrete engineering responsibility from your resume.

Contact

Open to backend, platform, and systems conversations.

This is intentionally more direct now. The contact section should help someone reach you quickly, not compete for attention.

Let's talk about backend systems, platform engineering, or infrastructure.

Reach out if you're hiring, collaborating, or just want to discuss scalable services, reliability, cloud architecture, or engineering systems.
