:: I TURN IDEAS INTO REALITY THROUGH CODE, MACHINING, AND ELECTRONICS ::
:: FROM CONCEPT TO WORKING PROTOTYPE ::
[ ABOUT.MODULE ]
>> PROFILE.SUMMARY
I DON'T JUST DESIGN SOLUTIONS—I BUILD THEM. WHETHER IT'S PROGRAMMING AUTOMATION TOOLS, MACHINING PRECISION PARTS ON A CNC, OR WIRING UP ARDUINO PROJECTS, I LOVE THE ENTIRE JOURNEY FROM CONCEPT TO WORKING PROTOTYPE.
MY PLAYGROUND SPANS BOTH DIGITAL AND PHYSICAL: I'VE CODED ENTERPRISE SYSTEMS AT INFOSYS, OPERATED WIRE EDM AND CNC MACHINES, BUILT MECHANICAL DISPLAYS FROM SCRATCH, AND TAUGHT STUDENTS HOW TO BRING THEIR OWN IDEAS TO LIFE.
WHAT DRIVES ME? THE SATISFACTION OF SEEING SOMETHING WORK FOR THE FIRST TIME—WHETHER IT'S A CLEAN G-CODE PROGRAM RUNNING ON A HAAS MILL, A PYTHON SCRIPT SAVING HOURS OF MANUAL WORK, OR A HOMEMADE WIND TUNNEL DEMONSTRATING FLUID DYNAMICS.

[ PROJECTS.ARCHIVE ]
SPLIT-FLAP DISPLAY
>> PROBLEM: WANTED RETRO AIRPORT-STYLE DISPLAY THAT ACTUALLY WORKS
>> SOLUTION: 3D-PRINTED MECHANICS + ARDUINO + STEPPER MOTORS +
C++ CODE FOR FLAP SEQUENCING. ITERATED UNTIL TIMING WAS SMOOTH AND RELIABLE.
DIY WIND TUNNEL
>> PROBLEM: TEACHING FLUID DYNAMICS WITHOUT SEEING AIRFLOW
>> SOLUTION: BUILT WORKING WIND TUNNEL FROM SCRATCH—DESIGNED
DUCT, SOURCED FANS, ADDED SMOKE VISUALIZATION. NOW STUDENTS SEE LAMINAR VS
TURBULENT FLOW IN ACTION.
HOMELAB AUTOMATION
>> PROBLEM: TIRED OF REPETITIVE TASKS, WANTED PRIVATE CLOUD
>> SOLUTION: BUILT HOMELAB SERVER WITH DOCKER CONTAINERS—
AUTOMATED FILE BACKUPS, N8N WORKFLOWS, TAILSCALE REMOTE ACCESS.
IF I DO IT TWICE, I AUTOMATE IT.
PDF CLEANUP BOT
>> PROBLEM: MANUAL PDF CLEANUP EATING 30+ HOURS PER RELEASE
>> SOLUTION: BUILT SELENIUM BOT IN PYTHON—CRAWLS WEB PAGES,
FINDS EMBEDDED PDFS, VALIDATES THEM, CLEANS BROKEN LINKS AUTOMATICALLY.
ONE SCRIPT = HOURS SAVED WEEKLY.
IOT EXPERIMENTS
>> PROBLEM: CURIOSITY + SPARE ARDUINOS = ENDLESS TINKERING
>> SOLUTION: BUILT SENSOR PROJECTS, MOTOR CONTROL SYSTEMS,
HOME AUTOMATION PROTOTYPES. SOME WORK PERFECTLY, SOME TEACH WHY THINGS FAIL.
EVERY PROJECT ADDS TO THE TOOLKIT.
HYBRID TURBOCHARGER
>> PROBLEM: COLLEGE PROJECT—IMPROVE ENGINE EFFICIENCY
>> SOLUTION: LED TEAM TO DESIGN AND FABRICATE HYBRID TURBO
SYSTEM. LEARNED EXHAUST DYNAMICS, BEARING SELECTION, THERMAL MANAGEMENT
THROUGH HANDS-ON TRIAL AND ERROR.
