Experience

Backend & DevOps Engineer at Scribble Network

Feb 2024 → now

Joined as the first backend hire and grew with the company. I own backend, database design, and infrastructure across Scribble's creator, brand, and ad products on AWS and GCP, working closely with the CTO on key architecture decisions.

Executed the CTO-directed move of core data from MongoDB to PostgreSQL for cleaner structure and faster queries, which made new features far easier to add.
Partnered with the CTO to migrate production from AWS to GCP for better cost efficiency, keeping the product live throughout.
Automated production deployments with GitHub Actions and set up log monitoring with Loki and Grafana.
Resolved a late-night production outage in 5–10 minutes (versus an estimated 1–2 hours) by using Cursor AI to speed up diagnosis and the fix.
Built Scribble for Creators (50,000+ creators, $500,000+ paid across 800+ campaigns), Scribble for Brands (Listed in Product Hunt's Top 3 AI Products of the Week), and Kili (250+ daily active developers), built in 4 days with Cursor AI: a public API server, an internal server, two developer integration packages, and the UI.
Built auth system from scratch: Magic links plus Google and X (Twitter) login.
Built Microservices for notifications and incoming webhooks, and a faucet that handles crypto payouts.
Built a crypto native Telegram bot that lets anyone send crypto using just a Telegram username.
Built Rabots: one-click bots that put funds into DeFi yield, so beginners skip the usual research and multi-step setup.
Wrote Smart Contracts in Solidity for EVM and Move for Sui to handle prediction markets and automated trading.
Use Cursor and Claude Code every day to ship faster.

Backend Engineer at BuidlersTribe

May 2023 → Feb 2024

Rebuilt BuidlersTribe's Drupal (LAMP) website as a MERN app, trading Drupal's limited built-in settings for a codebase we could fully customize.

Led the Drupal to MERN migration, which made the product easy to customize and sped up feature delivery by 30%.
Used the new stack to rebrand with a cleaner, easier-to-use interface, which grew product traction and pushed daily active users up.
Deployed and ran the app on AWS behind Nginx.
