Who I Am

About Me

Ashwath Kannan

I'm a Software Engineer focused on backend development, APIs, and system reliability. I currently work at Sage (formerly Fyle, acquired July 2025), where I build and improve features used across global expense management products — from internal tooling and card operations to API pipelines and deduplication systems.

Before full-time, I completed Google Summer of Code 2023 with the Oppia Foundation, shipped backend automation at EPACK Prefab that cut design cycles from 10 days to 2–3 days, and have been an active open-source contributor for over 2 years.

What drives me is solving practical engineering problems — making systems faster, cleaner, and easier for teams to maintain and extend.

Software Engineer — Backend
Nov 2024 – Present

  • Built self-serve internal tooling (Appsmith) for Customer Support to manage high-volume corporate card operations — eliminating developer intervention and reducing related support requests from 30+/month to near zero.
  • Identified root cause of 50%+ duplicate corporate card creation stemming from concurrent Amex and Yodlee feed activity; engineered auto-conversion and deduplication logic across both card ingestion flows.
  • Delivered a suite of Amex Virtual Card improvements — CRUD notification system, card detail editing, and monthly spend limit enforcement — driving 100%+ growth in virtual card usage within one month of release.
  • Hardened a corporate card data pipeline by integrating GPG-based public/private key encryption and configuring Docker volume mounts for secure production secret management.
  • Investigated a payment processor duplicate transaction ID issue through production data analysis; authored an Engineering Design document and landed on a data-backed solution.

Featured Projects

🌟
GSoC 2023 — Oppia Foundation
60% efficiency gain

Developed 6 full-stack features for Oppia's contributor dashboard, enhancing the translation review workflow. Collaborated with the Design Team on UI/UX, conducted user surveys to drive product decisions, and improved unit test coverage by 10%.

Python Angular TypeScript Full-Stack
🔐
OONI-ChainWatch
Certificate Transparency Research

Researched and developed a Python script to extract and parse X.509 certificate chains from OONI web connectivity measurements using gzip and JSON libraries for efficient .jsonl.gz file processing. Submitted valid certificate chains to Let's Encrypt's CT log with rate-limiting, exploring real-world certificate transparency pipelines.
