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

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

I don't just write code; I build ecosystems. I orchestrate my signature solutions to resolve complex problems. I am currently focused on bridging the gap between low-level hardware constraints and high-performance, visually fluid web interfaces. Whether it is routing zero-latency spatial data from an ESP32 or engineering web-based fluid physics, my goal is to 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.

πŸ› οΈ The Arsenal

  • Core Proficiencies: C/C++, Python, Java, HTML5/CSS3
  • Applied Experience: Kotlin, Dart, JavaScript
  • Frameworks & Ecosystems: Flutter, Flask, GSAP
  • Databases & Storage: MySQL, SQLite, SQLAlchemy, Flat-File Relational Engines
  • Tools & Modeling: Git, GitHub, AutoCAD, Blender
  • Hardware/IoT: ESP32, Arduino, Sensor Integration

πŸ† Featured Architectures

[Team Project - Founder, Solo Architect & Lead Developer] A decentralized IoT mobility ecosystem for the visually impaired. (Patent Pending)

Note: These are active beta prototypes meant for demonstration and testing purposes.

  • The Hardware: Custom wearable apparatus integrating a multidirectional spatial awareness array for zero-latency haptic response.
  • The Core Server: A robust Python-based API gateway acting as the ecosystem's nervous system, routing real-time telemetry and bi-directional data between the physical hardware, mobile app, and web interfaces. Implemented secure data pipelines for live optical telemetry streaming and an OS-bypassing SOS dispatch system.
  • The Website: Low-latency web portal featuring a WebGL digital twin interface to visually track hardware orientation and optical telemetry.
  • The Mobile AI: Memory-optimized app in a headless ambient state, unifying voice-navigated spatial AI with an OS-bypassing emergency routing protocol.

[Solo Project] A high-fidelity interactive prototype pushing the limits of native web technologies.

  • Live Link: 🌐 View Concept Website
  • Engineered complex GSAP scroll-triggered animations and physics-based CSS hover states.
  • Built a custom JavaScript dual-audio controller for synchronized multimedia playback without relying on heavy frontend frameworks.

[Solo Project - Hardware Engineer & Firmware Developer] A custom-built, smartphone-controlled mechatronic platform.

  • Hardware Engineering: Constructed a robust 4WD robotic chassis using a custom 20x12 cm (6mm thick) vibration-dampening wooden board, integrating an Arduino Uno R3 and an Adafruit L293D Motor Shield.
  • Embedded Firmware: Developed custom C++ logic for differential drive kinematics (skid-steering) and dynamic PWM speed reduction algorithms, enabling real-time smartphone control via an HC-05 Bluetooth serial link.
  • Power Architecture: Engineered an isolated power distribution system using a dedicated high-drain 18650 lithium-ion battery plant for the motors, successfully mitigating microcontroller brownouts during stall-current spikes.

[Team Project - Founder, Lead Architect & Lead Backend Engineer] An enterprise-grade, memory-safe clinical management ecosystem built entirely in C.

  • Custom Relational Database Engine: Architected a highly optimized, flat-file CRUD engine utilizing delimited text files, featuring file-lock semaphores to prevent data corruption during concurrent background saves.
  • Dynamic State-Machine Routing: Engineered the core logic pipelines to autonomously track and route patient data across 5 strict role-based access portals (Admin, Doctor, Reception, Lab, Kiosk).
  • Security & Memory Safety: Built a custom Hex-XOR cryptographic cipher for credential obfuscation and implemented strict dynamic memory allocation protocols (malloc/realloc) to guarantee Valgrind-safe execution and zero-crash stability.
  • Automated Document Generation: Programmed background modules to dynamically compile, format, and export clinical prescriptions, lab results, and itemized tax invoices directly to the local file system.
