I design and deliver production-ready full-stack systems using the MERN stack, Next.js and TypeScript. Experienced across AWS, Azure and GCP, I build APIs (REST/GraphQL), real-time systems (WebSocket, Pub/Sub), containerized microservices (Docker), and automated CI/CD pipelines (GitHub Actions / Bitbucket Pipelines). I also work with Python (FastAPI), C# (ASP.NET Core), Java and Go for backend services and data processing.
Notable: built a cloud-native digital signage platform supporting 1,000+ concurrent users and 10,000+ global displays with real-time content distribution and multi-tenant admin tooling.
- Frontend: React, Next.js, TypeScript, Vite
- Backend: Node.js, Express, FastAPI, ASP.NET Core, Java, Go
- Datastores / Caching: MongoDB, PostgreSQL, Redis, Elasticsearch
- Infra & DevOps: Docker, Kubernetes (basic), AWS / Azure / GCP, Terraform (intro), GitHub Actions, Bitbucket Pipelines
- Realtime & Messaging: WebSocket, Socket.IO, BullMQ, Pub/Sub, Kafka concepts
- APIs & Integration: REST, GraphQL, OpenAPI/Swagger
- Testing & Quality: Unit / integration testing, linting, performance tuning, security hardening
applications. Proven expertise in JS, TypeScript, React.js, Next.js, Python, and C# with hands-on experience in cloud
services (AWS, GCP, Azure) and Docker containerization. Successfully optimized system performance, enhanced security
protocols, and reduced deployment times for platforms serving 10,000+ users in digital marketing environments. Strong
background in RESTful APIs, microservices architecture, AI/ML integration, and DevOps automation practices.
