AJAY RAJU MJ.
Designing thermal & mechanical systems — and building the AI tools that make engineering work faster.
BETWEEN METAL
AND MACHINE LEARNING
I'm a Mechanical Engineering undergraduate at Government College of Technology, Coimbatore. My work sits in two places at once — on the shop floor, where I've handled fabrication, welding and quality control on GAIL (India) projects, and in code, where I build AI assistants that understand engineering.
CAPABILITIES
Six things I can take from a blank page to something that actually runs.
Mechanical Design & CAD
3D modelling and 2D manufacturing drawings in CREO and SOLIDWORKS — parts, assemblies and shop-ready documentation.
Thermal & Energy Systems
Heat transfer and thermodynamic sizing for reactors, condensers, industrial heating rigs and fuel cell stacks.
FEA & Simulation
Structural and thermal analysis in ANSYS APDL — load cases, material selection and design validation before you cut metal.
AI for Engineering
Domain-specific LLM assistants with Retrieval-Augmented Generation, grounded in standards, handbooks and design references.
Predictive Maintenance
Condition monitoring and sensor data acquisition, with ML models that flag degradation trends and estimate remaining useful life.
Process Data & Analytics
Temperature and process data pipelines visualised in Power BI to expose deviations from set conditions.
PROJECTS
Reactors, fuel cells and language models. Five builds that span the workshop and the terminal.
TORQ AI
/ 01A portable AI assistant built specifically for Mechanical Engineering. Uses Retrieval-Augmented Generation over standards, handbooks and design references so answers stay grounded in real engineering data instead of guesswork.
SPARROW AI
/ 02A fully local desktop AI assistant — runs a GGUF large language model on-device through llama.cpp with no cloud dependency. Includes voice input via speech recognition, text-to-speech replies and persistent conversation memory.
PYROLYSIS REACTOR
/ 03Designed and fabricated a batch-type reactor that thermally decomposes waste plastic in an oxygen-free chamber to yield liquid fuel, gas and char. Sized the reactor and condenser to the thermal load, selected high-temperature materials, modelled the assembly in CAD and ran trials across a controlled temperature range to study oil yield.
PREDICTIVE MAINTENANCE — FUEL CELLS
/ 04A condition-monitoring approach for PEM fuel cell stacks using voltage, current density, temperature and humidity. A machine learning model detects degradation trends and estimates remaining useful life ahead of failure.
AI-POWERED CNC
/ 05Winning concept at the Shark Tank Innovation Challenge — software that lets CNC machines interpret and execute natural language commands, collapsing the gap between intent and G-code.

THE JOURNEY
Started B.E. Mechanical Engineering
Joined Government College of Technology, Coimbatore — one of Tamil Nadu's oldest engineering institutions.
Intern — Sanjmar Industries, Chennai
Hands-on with industrial fabrication, material preparation, welding, assembly and quality control on projects for GAIL (India) Limited. Observed weld inspection and dimensional checks against drawings for shop-floor clearance.
Intern — Revo Technologies & Enterprises, Chennai
Worked on industrial heating systems, implemented temperature data acquisition for process monitoring, and analysed the recorded data in Power BI to identify deviations from set conditions.
Winner — Shark Tank Innovation Challenge
Took first place with an AI-powered CNC concept that lets machines interpret natural language commands. Also completed REVIT MEP certification through MSME.
President — Young Minds Club of GCT Youth
Leading a student service organisation focused on community initiatives and campus development, coordinating volunteers and planning events.
Building TORQ AI & Sparrow AI
Developing a RAG-based mechanical engineering assistant and a fully offline desktop AI, while pursuing thermal system and reactor design work.
