Bryan Julian Garzon

Systems and Software Engineer

Summary

I'm a productive, battle-tested software builder and computing connoisseur, with an attention to detail that is almost annoying. My varied experience spans not only multiple businesses, but also across multiple crafts in and out of computers, such as a decent knowledge of mathematical abstractions like categories, or unnecessarily detailed insight in computer networks and operating systems.

Experience

EPAM

2025 – 2026

EPAM is a global provider of software engineering and IT consulting services. It has a strong presence in the technology industry, offering a wide range of services to clients across various sectors.

I joined EPAM to work on a project for a major client in the e-commerce industry, where I am responsible for developing and maintaining software solutions that enhanced developer experience and streamlined internal processes, while also contributing to an initiative to support internationalization and localization efforts.

I used raw Scala's concurrent programming libraries, while pushing for the usage of ZIO and Cats Effect in the codebase, while implementing effect-based programming principles to improve the scalability and maintainability of the software solutions.

Ziverge

2024 – 2025

Ziverge focuses on developing and maintaining a library ecosystem to use effect-based programming for the Scala programming language. It also develop technology solutions and for all sorts of industries. I was there to augment a team developing software for one of the biggest players in the entretainment industry, if not the biggest.

  • My work involved implementing new endpoints – or removing them – on a GraphQL API Gateway, using Cats Effect and a complex but well integrated central schema that relied on code generation using AWS Smithy or GraphQL itself.
  • I wrote a 12K+ words article on ZIO.
  • I stumbled upon some work involving Terraform and related technologies.

Xebia Functional (Previously 47 Degrees)

2021 – 2024

Xebia Functional is a division of the consultant behemoth Xebia that focuses on functional programming, with a great emphasis in the Scala's Typelevel ecosystem.

  • I worked on a huge project for a music streaming serivice.
    • At this project, I worked in tooling for authenticating comunication between services, using Scala 3, and JWT/JWKS.
    • Used and tweak schema and API code generation using the over-powered AWS Smithy.
    • Enabled A/B experimentation with a clever encoding that used a KrakenD's plugin, which uses Go, and FS2, to create a pure mapping between experiments and users.
    • Touched upon a lot of technologies associated with devops, such as Github Actions and CDK.
  • Worked on internal projects, in which I demoed a way to SSR React from Scala on one of them.
  • Helped on a demo to demonstrate the power of LLMs and structured output for asisting CMS creation, using React.

Optic Power

2021

Optic Power (now defunct) was a consultancy enterprise mainly focused in the video-game industry, that made heavy use of the Elixir programming language, among other technologies.

  • Worked on a 'white-labeled' application to create and manage video-game tournaments, using an amazing stack made by the Ash Framework, Next.js, and a nice setup for comunicating both using GraphQL.
  • Used React and React Native for a huge platform that integrated with video-games and let users to bet with friends.

Puntored

2020 – 2021

My main goal was to provide quality code and good engineering to an application built with Flutter (Dart). I've proposed and developed a major refactor based on good practices and testing for the "Puntopay" application. My word in architecture and testing practices was taken into account when the company was trying to implement Go as a programming language suitable for a microservice-based infrastructure.

  • Created a demo to enable a transition from the typical Java monolith, to a gRPC-based microservice architecture using Go.

Foonkie Monkey

2019 – 2020

Foonkie Monkey is a digital agency that focuses itself on all sorts of software services, ranging from low-code apps, to fully-fledged digital platforms.

  • Worked on a website for a huge pharmaceutical that used C# as backend, and JS/TS as frontend.
