"There are no constraints on the human mind, no walls around the human spirit, no barriers to our progress except those we ourselves erect" - Ronald Reagan.

My name is Gogul Ilango. I'm passionate towards designing products that makes people's life better with focus towards Aesthetic, Design and Engineering.

Currently I work as a Physical Design Engineer + Full Stack Web Developer, who helps a team of intelligent minds at Qualcomm in designing cutting-edge chipsets (7nm, 14nm, 28nm) that millions of people around the world use it in their everyday life.

I'm one of the Deans at Chennai School of AI which is a rocking community of AI enthusiasts, college students, developers, industry experts and entrepreneurs where we discuss, analyze, prototype, learn and share AI related stuff with the world for free under the guidance of our director Siraj Raval.

I completed my masters in VLSI Design and Embedded Systems at Anna University, MIT Campus, Chennai with a gold medal. I completed my bachelors in Electronics and Communication Engineering at Thiagarajar College of Engineering, Madurai.

My technical areas of interest are

  • VLSI Design
  • Automation
  • Embedded Systems
  • Machine Intelligence
  • User Experience
  • User Interface Design
  • Web Design
  • Full-stack Web Development
  • Music Composition
  • Music Production

In this personal website, you will find collection of my thoughts, notes, tutorials and resources based on my experience in technology. Some of the areas that I wish to learn and write in this blog are VLSI Physical Design, Low Power VLSI Design, Static Timing Analysis, Machine Learning, Deep Learning and Computer Vision. I still learn by myself about the technical topics that I write here so that I get a clear understanding of it.

I do this mainly during my free time because

  • It helps me learn these topics better by making me read, write and evaluate myself first before sharing it here.
  • It provides me a chance to organize my technical interests so that I can refer to it later.
  • It gives me a chance to share my knowledge to the world where it might help someone somewhere.

I also share resources to help students find useful information in the internet. If you like my posts, kindly share it with people interested in these topics. It really mean so much to me. Hope you find something useful in my blog 😉

My passions are Music and Art. I love creating tunes, producing and arranging music using Digital Audio Workstations (DAW), playing keyboard and writing lyrics. You can listen to my music here.
