High-Reliability Backend Systems
Engineered for decoupled Java microservices, ACID transactional integrity, enterprise-grade security, and complementary high-concurrency Go services.
Java Microservices & Spring Boot Ecosystem
Decoupled modular architectures, Eureka Service Discovery, Spring Security, JPA/Hibernate, and robust RESTful APIs.
High-Concurrency Systems in Go (Additional)
Non-blocking worker pools, channel streaming, lightweight gRPC microservices, and sub-10ms P99 latencies.
Databases & Transactional Consistency
Query optimization and indexing on PostgreSQL, MariaDB, and SQLite WAL with strict ACID consistency.
Cloud Infrastructure, Docker & Kubernetes
Multi-stage Docker builds for JVM and Go, K8s orchestrations, automated CI/CD pipelines, and zero-downtime rolling deploys.
From HTTP Request to Persistent Commit
The full lifecycle of every inbound payload handled with zero allocations and strict deterministic validation.
Edge Ingress & Token Bucket
Inbound traffic hits reverse proxy with strict IP rate limiters, payload size inspection (1MB max), and security headers.
Goroutine Worker Dispatch
Buffered channel passes the request to idle worker pools. Non-blocking concurrency guarantees zero bottleneck on thread pools.
Data Stream & Validation
Input sanitation, JWT claim verification, and data marshaling executed in memory with strict type validation.
Atomic WAL Persistence
Synchronous write-ahead log write to SQLite3 / PostgreSQL replica cluster. Telemetry emitted to Prometheus in < 2ms.
Battle-Tested Backend Infrastructure
Featured Engineering Projects
Battle-tested applications, open-source libraries, and cloud deployments running in production.
Interactive REST API Tester
Dispatch a live HTTP GET request directly to the running Go backend server on /api/v1/public/info.
