Full-stack engineer with 7.5+ years of experience building scalable frontend platforms and backend systems.

I specialize in:

• Modern React + TypeScript architectures
• Java / Spring Boot / NodeJS / ExpressJS microservices
• Distributed systems & async workflows
• Event-driven pipelines (Kafka / Redis)
• Developer tooling & design systems

I enjoy building production-grade systems with focus on reliability, performance, and clean architecture.

Currently exploring:

• Distributed job orchestration
• Design systems
• MSME platforms
• AI-assisted learning (RAG)

Java · Spring Boot · Redis · Kafka · PostgreSQL · Docker

A distributed workflow engine designed for ETL pipelines and microservice orchestration.

Highlights

• DAG-based task execution
• Retry + exponential backoff
• Dead-letter queues
• Horizontal scaling
• JWT authentication
• Prometheus + Grafana observability
• PostgreSQL persistence

Built to handle:

• background jobs
• async workflows
• fault-tolerant pipelines

👉 Focused on real-world reliability patterns.

Microservices · Event-Driven Systems · Distributed Workflows

• 7.5+ years building full-stack systems with React and Java
• Design systems using the SCARD approach — Scalable, Consistent, Available, Reliable, Durable
• Strong focus on clean architecture, fault tolerance, and production stability
• Backend engineering with event-driven pipelines and async workflows (Kafka, Redis)
• Built React micro-frontends with shared design systems and independent deployments
• Led performance optimization for high-traffic user journeys, backend services, and PostgreSQL workloads
• End-to-end ownership of features: requirements → system design → coding → deployment → observability

Comfortable working across frontend, backend, infra, and system design.
