I'm a full-stack engineer who thrives on problem solving and building things that scale. I'm deeply interested in cloud infrastructure & DevOps — from containerizing services to designing resilient CI/CD pipelines. Whether it's crafting pixel-perfect UIs or optimizing database queries, I enjoy working across the entire stack.

• ⚡ Full‑Stack Engineering — Architecting high-performance web applications with React, Next.js, TypeScript, and Node.js, with real-time features via Stream Chat and AI-powered experiences using Llama/Ollama.

• 🔗 APIs & Distributed Systems — Engineering fault-tolerant REST and event-driven APIs, microservices with Nginx reverse proxies, and asynchronous workers with structured telemetry, caching, and resilient throughput.

• 🗄️ Databases & Data Modeling — Designing scalable schemas across PostgreSQL, MongoDB, and Qdrant, optimizing complex queries, and enforcing robust JWT/OAuth authorization with bot protection via Cloudflare Turnstile.

• ☁️ Cloud Infrastructure & DevOps — Provisioning production-grade AWS EKS clusters with Terraform, managing Kubernetes workloads with Helm (Cluster Autoscaler, ALB Controller, Cert-Manager, CSI drivers), and containerizing services with Docker.

• 🏗️ Systems Programming — Building bare-metal OS kernels in Rust with custom memory management (4-level paging, heap allocators), interrupt handling (GDT/IDT), async task executors, and hardware-level VGA drivers in no_std environments.

• 🤖 Machine Learning & Computer Vision — Training reinforcement learning agents with PPO/Stable Baselines3 and custom CNN architectures, and building real-time CV pipelines with OpenCV for state extraction, OCR, and template matching.

• ✅ Testing, CI/CD & Reliability — Implementing comprehensive unit, integration, and E2E suites with vitest, Playwright and Jest, automated via GitHub Actions pipelines with quality gates.

• 🏢 Architected and delivered core SaaS features and real-time platforms using React, Next.js, and TypeScript, integrating AI-powered experiences and Stream Chat for high-engagement user workflows.

• 📈 Engineered scalable RESTful API endpoints and optimized SQL query pipelines, reducing backend response times by 35% and improving data retrieval speeds across 10,000+ transaction records.

• ☸️ Provisioned production-grade EKS clusters with Terraform, configuring IRSA, managed node groups, Cluster Autoscaler, ALB/NLB controllers, Cert-Manager, and CSI drivers for persistent storage and secret management.

• 🐳 Containerized and deployed secure microservices architectures on AWS EC2 with Docker and Nginx reverse proxies, enforcing API key authentication, rate-limiting, and role-based access control.

• 🧠 Built ML training pipelines and autonomous agents using PyTorch, PPO, and custom CNN architectures, with real-time Computer Vision pipelines processing live video streams at 30 FPS via OpenCV.

• 🦀 Developed a bare-metal OS kernel in Rust with custom memory management, hardware interrupt handling, and an async task executor — demonstrating deep systems-level engineering expertise.
