Sumit Sawant

Backend Engineer LotusFlare Pune, IN

Backend systems,
built to stay fast.

Eight years across telecom platforms, workflow orchestration, and the production systems behind them — from implementation through the on-call pager and the customer call when it breaks.

Selected work

Three of eight years

01

Network API Marketplace

LotusFlare · 2026 — present

Backend systems that let communications service providers expose, manage, and monetise network APIs — publishing, metering and billing, and developer onboarding.

Scope
API publishing, metering & billing
Domain
Telecom / CSP

02

Freshservice Orchestration

Freshworks · 2020 — 2026

Scaled the orchestration platform behind Freshservice — the layer that runs workflow automations across third-party applications — and took its median run from three minutes to under a second.

Throughput
1.25B transactions
Latency
3 min → < 1 s
Accounts
6,058
Stack
Java, Vert.x

03

Production ownership

Freshworks · 2020 — 2026

Owned reliability for a platform at billion-transaction scale: security hardening, escalation and SLA paths, and mentoring engineers on production readiness. Informed by 1,000+ L2 escalations and 500+ customer calls.

Practice
Security hardening, SLA
Also
Mentorship

Most of the latency and reliability wins came from being on the call when it broke — then fixing the system rather than the ticket.
