I'm Boopathi, also known as Boopathi Mahendran — a Full Stack Developer, Python Developer and IoT Developer from Tamil Nadu, India. I build fast web applications with JavaScript and Python, and connected hardware with the ESP32. Software and electronics, one portfolio.
About
Boopathi Mahendran, also known as M Boopathi, is a Full Stack Developer, Python Developer and IoT Developer from Tamil Nadu, India — equally at home writing a REST API and soldering a sensor onto an ESP32.
I'm an Information Technology student at M. Kumarasamy College of Engineering, Karur, and I work as a freelance web developer alongside my degree. On the software side I build responsive front ends with HTML, CSS and JavaScript, and back ends with Node.js, Python and Flask. On the hardware side I design IoT and embedded systems around the ESP32, Arduino and Raspberry Pi — sensing real-world data, pushing it to the cloud, and acting on it automatically.
My work spans cloud computing, artificial intelligence and cybersecurity: a self-hosted 1 TB Raspberry Pi storage server, a Python computer-vision OCR analyser, and HydroSmart, an ESP32 water-management system driven by a model-based reflex agent. I believe the strongest software engineers are the ones who can cross the line between code and circuit — so that's the portfolio I'm building. There's a longer profile of Boopathi Mahendran if you want the full background, and I write up algorithm problems in Boopathi's LeetCode solutions.

Selected work
Web apps, IoT hardware and AI tools — each one built end to end, from the first sketch to hosting.
IoT · Embedded
An IoT smart water management system pairing ESP32 sensing with a Python model-based reflex agent that controls the motor automatically from real-time flow, temperature, current and voltage readings.
Game
A real-time multiplayer Tic-Tac-Toe game built with Python, Flask and Socket.IO — live opponent matching, score tracking and a fully responsive front end.
Web · Educational
A web-based CGPA and GPA calculator for engineering students, pre-loaded with subjects and credit weightings. Enter your grades and get instant semester GPA and cumulative CGPA results.
Cloud / IoT
A self-hosted 1 TB personal cloud built on a Raspberry Pi with an SSD and Python — a private, always-on alternative to Google Drive running on my own hardware.
Healthcare · IoT
A multi-stage IoT assistive system for differently-abled users, enabling device control through finger motion, eye blink or voice input using embedded sensors and an ESP32 controller.
AI · Computer Vision
A Python computer-vision tool that extracts text from LinkedIn profile screenshots with OCR, then evaluates skills, generates a profile score and produces NLP-driven career recommendations.
Web App
A JavaScript and Node.js web app for tracking and analysing expenses, with real-time data visualisation and monthly budget management.
Skills
HTML5, CSS3, JavaScript — responsive, accessible, beautiful interfaces.
Node.js and Python for APIs, server logic, and automation scripts.
Raspberry Pi, IoT sensors, embedded systems and cloud connectivity.
Git, VS Code, Linux, and cloud platforms for the full dev workflow.
Cloud storage, deployment pipelines, distributed system fundamentals.
Browser-based games using HTML5 Canvas and JavaScript game loops.
Network security, reconnaissance and vulnerability assessment — plus secure coding practices that keep web apps and IoT devices hardened.
