Explaining something is the fastest way to find out whether I really understand it. Since 2021 I’ve taught more than 100 students, mentored developers at GeeksforGeeks and Airtribe through problem solving, system design and low-level design, written an ebook on modern JavaScript, and published the interview prep material I use in my sessions.
Airtribe, 2024 – 2025
Mentored learners in Airtribe’s software engineering program on the Node.js backend track: low-level design sessions on OOP, SOLID, design patterns and case studies such as a parking lot, an elevator and Splitwise, mock interviews, and reviews of the cohort’s own projects. The decks and interview kit under Open material come from these sessions.
GeeksforGeeks, Oct 2022 – Oct 2023
A year of sessions helping students and working professionals get better at problem solving, coding and system design, with the MERN stack as the common ground.
Growing Stars, Oct 2021 – Oct 2022
Taught more than 100 students across the United States in over 250 hours of live sessions, covering Python, JavaScript programming, and data structures and algorithms.
Ebook on Gumroad, January 2023
An ebook that covers the features and best practices of modern JavaScript, with every topic taught through code you write yourself.
