SDE 1 with production experience deploying microservices on AWS and GCP, handling 1,500+ concurrent users and 1,000+ real-time event pollers. I work across the backend stack Go (Gin), Java (Spring Boot), Node.js and ship full-stack features with Next.js. Focused on system design, API performance, and writing code that holds up under real load.

About

Background

Backend & Full Stack Engineer focused on building production-grade microservices and scalable distributed systems. I design clean architectures, optimize cloud deployments on AWS and GCP, and ship features that hold up under real production load.

Committed to solving complex engineering problems from high-concurrency API design to event-driven pipelines and delivering reliable, maintainable systems through pragmatic engineering and strong collaboration.

Current Focus

Designing and building resilient microservices and backend infrastructure high-performance REST APIs, event-driven systems (Redis Streams, Kafka), and scalable data stores. Currently working as SDE 1 at Tech Tvara, shipping full-stack features on a live sales platform.

Productionizing services with containerization and orchestration (Docker, Kubernetes), CI/CD pipelines (GitHub Actions, GitLab), and cloud platforms (AWS, GCP). I prioritize observability, automated testing, and performance tuning to meet reliability and scalability objectives.

"Turning tea into code and random ideas into slick digital experiences (and occasionally something questionable)."

Backend & Microservices

High-performance REST APIs and distributed systems (Go, Java Spring Boot, Node.js) designed for scalability and reliability handling 1,500+ concurrent users in production.

Cloud, DevOps & CI/CD

Cloud-native architectures on AWS and GCP, CI/CD pipelines (GitHub Actions, GitLab), and container orchestration (Docker, Kubernetes) for repeatable, secure deployments.

Database & Caching

Design and optimization of SQL/NoSQL databases and caching strategies (PostgreSQL, MongoDB, Redis, Kafka) to achieve low latency and high throughput.

Full Stack Web

End-to-end web features using Next.js, Angular, and TypeScript from RESTful API design through to responsive frontend delivery.

SSEW (Client)

Contract - Backend & DevOpsProject documentation

Led backend and DevOps for a polyglot microservices commerce platform, built a Spring Boot commerce service (auth, RBAC, JWT, catalog, CMS, orders) and a high-throughput Go telemetry service for event-driven long-polling. Handles 500-1,000 concurrent users and 1,000+ pollers at under 300ms latency.
Implemented resilient event-driven workflows using Redis Streams and gRPC, secured media handling with S3 presigned URLs, JWT-based RBAC with token rotation, and async email notifications with exponential backoff.
Productionized with Docker and GitHub Actions CI/CD, deployed to AWS EC2 behind Nginx. Commerce service achieves sub-400ms cached and under 900ms non-cached response times. Integrated Sentry for production observability.
