Tech Lead / Staff Engineer with 10+ years of experience designing and building scalable, business-critical backend systems.
I work hands-on while leading architecture, system design, and engineering execution for high-impact platforms.

• Lead backend and platform engineering initiatives
• Design systems from 0 → 1 and scale them reliably
• Own architecture decisions for high-traffic, high-availability systems
• Mentor engineers and drive technical excellence
• Translate business problems into robust technical solutions

• Payments & Financial Systems
• Order Management Systems (OMS)
• Subscriptions & Billing
• Logistics & Supply Chain
• Invoicing & Reporting Platforms

Languages

• Java (Primary), Python, NestJs

Backend & Architecture

• Spring Boot, Spring Data JPA, Hibernate
• REST APIs, Event-Driven & Async Systems
• Microservices Architecture

Databases & Caching

• PostgreSQL, MySQL
• MongoDB, Redis

Messaging & Streaming

• Kafka

Cloud & DevOps

• AWS (EKS, ECS, EC2, S3, CloudWatch)
• Docker, Kubernetes
• CI/CD Pipelines

Observability & Reliability

• Prometheus, Grafana
• OpenTelemetry
• Structured logging & alerting

(See pinned repositories below 👇)

• Payment Platform
  Designed idempotent APIs, async workflows, and failure-safe processing

• Microservices at Scale
  Service boundaries, resilience patterns, inter-service communication

• Observability Stack
  End-to-end metrics, logs, and tracing for production systems

• System Design POCs
  Real-world backend design problems with clear trade-offs

Each project focuses on design decisions, scalability, and operability, not just code.

• Design for failure first
• Make trade-offs explicit
• Prefer simple, maintainable solutions
• Optimize for long-term ownership and reliability

I share practical insights on:

• System design & architecture
• Scaling backend systems
• Tech leadership lessons
