Full-Stack Developer | AI Engineer | Hardware-IoT Architect | UI/UX Engineer | Mobile Architecture

"Engineering is the translation of abstract intent into physical reality."

I am a B.Tech CSE student, a 3x hackathon laureate, and a full-stack developer specializing in scalable, end-to-end systems. I don't just write code; I build ecosystems. I orchestrate signature solutions to resolve complex problems by architecting low-latency IoT ecosystems, multi-agent AI pipelines, and AI-driven B2B SaaS platforms. Proficient across embedded C++, robust Python backends, and high-performance interfaces, my goal is to solve complex real-world engineering challenges and build software that seamlessly escapes the screen.

πŸš€ Architecture & Engineering Focus

  • Modern Full-Stack Web Architecture: Designing highly responsive, scalable, and performant web applications using the React ecosystem and Next.js. I focus on optimized state management, server-side rendering (SSR), and building modular components that deliver fluid user experiences.
  • IoT & Embedded Ecosystems: Architecting decentralized, dual-microcontroller hardware nodes (C/C++, ESP32, Arduino) that interface seamlessly with real-time cloud environments.
  • Persistent Mobile Systems: Developing memory-optimized native applications (Kotlin, Flutter) designed to survive aggressive OS background constraints and run headless AI processes.
  • Thematic UI & WebGL: Engineering high-performance web portals (JavaScript, Three.js/HTML, CSS) with interactive 3D digital twins, GSAP animations, and fluid physics rendering.
  • System Design & Databases: Structuring scalable B2B architectures with AI-driven recommendation engines, and engineering custom flat-file relational databases utilizing dynamic state-machine routing.
  • Backend Architecture & API Routing: Architecting robust Python-based routing servers that act as the central nervous system for IoT ecosystems. I focus on bridging physical hardware and frontend interfaces through low-latency telemetry routing, real-time state synchronization, low-latency data pipelines for live optical streaming, and automated SOS dispatch routing.
  • Memory-Safe Systems Programming: Architecting monolithic software applications and custom database engines in C/C++, focusing on strict dynamic memory management, pointer arithmetic, and custom cryptographic security layers.
