Work Experience

Software Engineer

2019 - PRESENT

Axilis

Developed a robust and highly scalable service that listens to all changes that affect bets, applies them, and sends them to downstream services using Kafka.
Created and implemented an algorithm that reduced bet settling time by 100x, greatly increasing the throughput of a critical service.
Designed a general-purpose Kafka processing library that's used by dozens of projects in the company. The library significantly reduced the time needed to set up a new microservice—from two weeks to two days.

Solution Architect

2017 - 2019

HashCode

Developed a traffic simulator for a proprietary traffic control system.
Created multiple tools that a telecommunications company used to deploy new equipment to more than 1,000 base stations all over the country. Significantly reduced the time needed and the number of errors in the whole process.
Developed a web interface for an application that automates base station installation and configuration.

Technologies: Scala, Java

CTO

2015 - 2017

Smart Lumies

Developed software for educational smart toy cubes for children. Each cube had six LED lights, an accelerometer, and a Bluetooth transmitter inside, and supported various games via a mobile application.
Built the mobile Android application that connected to the cubes via Bluetooth.
Developed a Scratch-like application that children could use to easily create and play their own games.

Technologies: Bluetooth LE, Android, Arduino

Experience

Betting Ticket Service

A robust and highly scalable service, written in Go, that keeps all tickets up to date. The service uses Kafka for communicating with other services, listens for the events that happened, and applies those events to the tickets, ensuring consistency. I was the sole developer working on this service, communicating with other teams to ensure everyone's requirements are met.
