🧭 Engineering Principles

⚙️ Backend	🧱 Architecture	🚀 Performance	🛡️ Reliability
Clean APIs	Loose coupling	Cache intelligently	Design for failure
Async where useful	Clear boundaries	Measure first	Idempotent operations
Strong contracts	Event-driven flows	Optimize bottlenecks	Observability first
Secure by default	Scalable data models	Efficient concurrency	Graceful degradation

🔭 What I Actually Work On

⚙️ Service Engineering

Java · Spring Boot

REST APIs, transactions, validation, concurrency, security and maintainable service boundaries.

🔁 Distributed Workflows

Kafka · Async Processing

Consumer groups, retries, DLQs, idempotency, eventual consistency and failure recovery.

🗄️ Data & Performance

MySQL · MongoDB · Redis

Indexes, query tuning, caching, locking, data modelling and performance bottlenecks.

🛡️ Reliability

Resilience · Observability

Timeouts, circuit breakers, graceful degradation, logs, metrics, traces and production debugging.

☁️ Cloud Delivery

AWS · Docker · CI/CD

Containerized services, cloud integrations, configuration, secrets and deployment workflows.

🧩 System Design

HLD · LLD · Patterns

API boundaries, scaling decisions, design patterns, trade-offs and systems that remain understandable as they grow.

Problems I like solving

High traffic API      → caching + concurrency + database tuning
Duplicate requests    → idempotency + distributed locking
Slow dependencies     → timeout + retry + circuit breaker
Async processing      → Kafka + consumer groups + retry/DLQ
Growing data          → indexing + partitioning + scalable storage
Production failures   → logs + metrics + traces + graceful recovery

🤝 Let's Build Something Interesting

I enjoy conversations around Java, backend engineering, distributed systems, databases, system design, AWS and developer tools.
