👋 About

I'm a Backend & Platform Engineer who builds cloud-native, distributed systems — event-driven microservices on Kubernetes, exactly-once payment pipelines, and infrastructure-as-code on AWS. I currently own enterprise quality engineering as an SDET at Cognizant, and I engineer the production backends those systems depend on.

My foundation spans research-grade software (ISRO, DRDO) and production delivery — CI/CD, observability, and chaos-tested resilience. I build systems that are scalable, observable, and correct by design.

role:        Backend Engineer · Platform Engineer · SRE
currently:   NexusPlatform (1M+ orders/day) · Aegis (AI-powered self-healing backend)
strengths:   Distributed systems · Cloud infra · Event-driven architecture · Quality at scale
location:    Pune, India
open_to:     Full-time backend / platform / infrastructure roles

📊 Impact in Production

Reliability Performance Velocity
Zero critical payment defects in production −45% p99 latency (3 bottlenecks resolved) −40% regression execution time
99.9% API uptime @ 500+ concurrent users −30% API response time (Ridecell) −60% manual testing effort
90%+ automated code coverage 10TB+ remote-sensing data processed (ISRO) −30% production defect escape rate

🚀 Flagship Projects

NexusPlatform

Cloud-Native Distributed Commerce Backend · Go

Event-driven microservices designed for 1M+ orders/day.

  • Saga orchestration — distributed transactions, no 2PC
  • CQRS + Event Sourcing — split read/write, full audit trail
  • Redlock — distributed mutex across a 3-node Redis quorum
  • Outbox pattern — guaranteed delivery, no dual-write
  • Circuit breaker + sliding-window rate limiter (Lua)
  • AWS EKS · MSK (Kafka) · Istio mTLS · canary deploys
  • OpenTelemetry · Prometheus SLOs · Grafana · chaos tests

Go Kafka Kubernetes Terraform AWS Istio gRPC

Aegis Platform

AI-Powered Self-Healing Test Orchestration · Python

Async backend that heals broken UI selectors automatically.

  • Self-healing engine — DOM heuristic scoring → Claude LLM fallback → hybrid agreement
  • Async FastAPI · hexagonal (ports & adapters)
  • JWT + RBAC auth · BOLA/IDOR-safe object authorization
  • Redis pub/sub live run events · arq worker queue
  • SQLAlchemy 2.0 async · Alembic · Prometheus RED metrics
