Hey, I'm Annu 👋

What I'm focused on

I'm a solo founder and builder exploring how intelligent systems work — from electronics and embedded systems to IoT, robotics, machine learning, and AI.

My approach is simple:

Understand the fundamentals. Build real systems. Break things. Debug them. Go deeper.

I'm currently building my foundation in embedded systems and hardware while continuing to explore AI and intelligent systems from first principles.

My long-term interest is in building and researching intelligent physical systems at the intersection of:

Embedded Systems → IoT → Robotics → AI


Current learning journey

Embedded Systems

  • ESP32 & microcontrollers
  • GPIO, digital input/output
  • Sensors & actuators
  • PWM, ADC & interrupts
  • UART, I²C & SPI
  • Embedded programming
  • Hardware debugging

IoT

  • Connected devices
  • Wi-Fi & BLE
  • MQTT and device communication
  • Sensor data systems
  • Cloud-connected hardware

Robotics

Currently building toward:

  • Motor & servo control
  • Sensor integration
  • Sensor fusion
  • Control systems
  • Autonomous systems
  • Robot perception

AI & Intelligent Systems

Exploring:

  • Python for AI/ML
  • Mathematics for machine learning
  • Machine learning foundations
  • Edge AI
  • Computer vision
  • Embodied AI
  • Intelligent and autonomous systems

Projects

I'm building my portfolio as a progression rather than a collection of random tutorials.

Embedded Fundamentals
        ↓
Connected IoT Systems
        ↓
Sensors & Control
        ↓
Robotics
        ↓
Perception & Edge AI
        ↓
Intelligent Autonomous Systems

Each project will focus on understanding:

  • How the system works
  • Why it works
  • Where it fails
  • How to debug and improve it
  • What capability it adds to the next system

Software & product background

Before shifting my primary focus toward hardware and intelligent physical systems, I spent time building software products and exploring the startup ecosystem.

My experience includes:

Next.js FastAPI PostgreSQL Python TypeScript

This background continues to be useful as I explore the software side of IoT, robotics, AI systems, and intelligent products.


Founder journey

I'm also building an audience and exploring real problems worth solving.

Previously, I worked on Nexra, an experiment around helping founders think more critically about startup decisions.

That experience taught me something important:

Building technology is not enough. You need to understand the problem, the user, and whether the solution actually deserves to exist.

Right now, I'm focused on learning, building, sharing the journey publicly, and discovering problems where technology can create meaningful value.


Currently

  • Learning embedded systems with ESP32 and sensors
  • Building hands-on hardware experiments and projects
  • Working toward IoT and robotics
  • Learning AI/ML from first principles
  • Building a long-term portfolio of intelligent systems
  • Sharing the journey in public
  • Shooting nature photography at QuientNature

Philosophy

I don't want to just learn how to use tools.

I want to understand the layers underneath them.

Physics
   ↓
Electricity
   ↓
Semiconductors
   ↓
Transistors
   ↓
Logic & Digital Systems
   ↓
Computer Architecture
   ↓
Programming
   ↓
Algorithms
   ↓
Machine Learning
   ↓
AI
   ↓
Intelligent Machines

The goal is not to rush through the stack.

The goal is to understand enough of each layer to build better systems on top of it.


Let's connect

I'm interested in meeting people working on or exploring:

  • Embedded systems
  • IoT
  • Robotics
  • AI & machine learning
  • Edge AI
  • Intelligent systems
  • Developer tools and technology startups

Feel free to connect or follow along as I build.
