An uptime-critical NestJS service that continuously monitors smart contract events across decentralized networks, deserializes EVM event logs, and synchronizes state with downstream transactional microservices in real time.

A horizontally scalable realtime messaging service engineered with Node.js, WebSockets, and a Redis Pub/Sub distributed backplane, designed for low-latency multi-room chat, presence detection, and message broadcast.

An asynchronous evaluation engine built with Django REST Framework (DRF), Celery, and LLaMA-based model inference that evaluates subjective technical interview answers against deterministic scoring rubrics.

A high-integrity NestJS microservice dedicated exclusively to executing and monitoring blockchain write transactions, isolating cryptographic signing keys, managing transaction nonces, and ensuring auditability.

An open-source, modular hardware and signal processing architecture for a 10.5 GHz Pulsed Linear Frequency Modulated (PLFM) phased-array radar system, enabling low-cost RF target detection, range resolution, and beamsteering experimentation.

A high-throughput live broadcasting microservice built with NestJS, RabbitMQ, and WebSockets that consumes rapid odds, scores, and match events from upstream message brokers and broadcasts real-time updates to connected clients.

An enterprise Kubernetes and Infrastructure-as-Code (IaC) platform engineered with Terraform, AWS EKS, Ingress-Nginx on NLB, External Secrets Operator, and ArgoCD for automated, zero-downtime GitOps continuous delivery.
