Lead Software Engineer · Bengaluru, India
I build platforms that hold under load.
I’m Sai. For ten years I’ve worked on the parts of a product that have to survive traffic: authentication, payments, registration, migrations. Currently leading foundation work at Goldcast, now part of Cvent.

About
I like the unglamorous work: dependency analysis, observability, developer tooling, the cutover plan. I mentor engineers, review architecture, and use AI tools across the SDLC to move faster without lowering the bar. The measure is simple: fewer incidents, faster jobs, happier customers.
- Leading teams. Led a team of 2–3 engineers end to end at Jio, and lead foundation tracks at Goldcast — setting direction, reviewing architecture, and owning outcomes.
- Cross-team delivery. Moved GC Auth into Cvent infrastructure through cross-team dependency analysis and decoupling of legacy systems; at Embibe I ran platform tracks spanning monetisation, security and enterprise onboarding.
- Guiding juniors. Mentor engineers through regular architecture reviews and hands-on guidance, raising the bar on design, code quality and ownership.
