Building for the web
Founding technical lead · 10+ years
Sanket
Joshi.
Frontend tech lead who builds teams from scratch, coaches engineers and ships React, TypeScript and Node.js products.

01 / The approach
Lead alongside.
Not from above.
I'm a frontend tech lead with 10+ years across EPAM Systems, Excellarate and Cybage. I've led cross-functional UI teams, driven architecture decisions and shipped scalable React, TypeScript and Node.js products, while hiring developers, running 1:1s and growing engineers toward independence. As a Certified Scrum Master and long-time trainer I bring structure to ambiguity, and I still write code alongside the team.
