I designed and built the complete back end for Illuvium Deathmatch as the only back-end engineer on the project.

The back end is built on AWS serverless and handles matchmaking, game progression, rewards, leaderboards, analytics, blockchain integration, and operational tooling. I designed the event-driven workflows, the DynamoDB data model, and the Immutable zkEVM integration while working closely with the game team as gameplay evolved.

One of the biggest challenges was keeping the back-end flexible enough to support constantly changing game rules without turning it into a maintenance nightmare.

Dental Lab Guru is a SaaS platform for dental laboratories that helps manage cases, production, deadlines, deliveries, invoicing, and communication.

I designed and built the back end from scratch and later re-architected it towards Node.js and an event-driven architecture as the product grew. Besides development, I worked directly with customers to understand their workflows and decide which features should be built next.

The most rewarding part has been seeing laboratories in different countries use the same product while continuously shaping it through their feedback.

I built MVP-DB because I wanted a simpler way to create PostgreSQL databases for new projects.

It is a serverless, multi-tenant platform that provisions isolated databases in seconds while automatically handling authentication, billing, backups, and day-to-day operations. The goal was to remove as much operational work as possible so developers could focus on building their applications instead of managing infrastructure.

I designed the entire platform around AWS serverless with simplicity, predictable pricing, and low operational overhead as the main goals.
