What I'm looking for

I’m looking for a backend role where I can build high-availability, multi-tenant APIs and distributed processing systems—optimizing performance, ensuring data consistency, and shipping reliably in cloud-native environments.

I’m a Senior Backend Engineer with 7 years of experience designing and scaling high-availability, cloud-native backends for a B2B SaaS platform at Clootrack. I focus on robust APIs, distributed task processing, and multi-tenant architectures that stay consistent and dependable under load.

At Clootrack, I built a scalable authentication backend using JWT with MFA (TOTP + email OTP) and federated OIDC, and I replaced Azure AD B2C with self-hosted Zitadel to gain full control over auth flows. I also designed a Django + Celery data processing backend to ingest and asynchronously process Excel datasets, with validation, transformation pipelines, and data-science-ready outputs.

I’ve driven measurable impact—cutting infrastructure costs by ~50% (₹60L → ₹30L/month) through improved deployment and autoscaling strategies, reducing onboarding time from 2 days to 2 hours via automated multi-tenant workflows, and delivering zero-downtime microservices deployments with Docker, Kubernetes, and GitHub Actions. I care deeply about performance optimization, data safety, and operational reliability.

Nov 2019 - Sep 2022 (2 years 10 months)

Implemented Celery/Redis asynchronous task processing to decouple heavy jobs from request lifecycle and improved API response times for ~200 background jobs/day. Optimized database queries and caching (Redis TTL/invalidation), reduced error rates, supported 5× peak traffic via load balancing, and strengthened reliability with private VPC/least-privilege IAM and automated backups (1-hour RPO) with
