About

Building the foundations that product teams rely on.

I'm Bart, a Software Architect based in Malta specialising in frontend solutions. I work on the structural decisions that shape how teams build, maintain, and scale their web applications at enterprise level.

I've spent 8+ years at Betsson Group, where I've led the transformation from monolithic frontends to a micro-frontend architecture built on native web components and event-driven communication. Before that, I ran my own development business for nearly a decade, delivering full-stack solutions for clients across Europe.

Outside of work, I'm building GridChief, a platform for managing competitive sim racing leagues. I bring a full-stack perspective to frontend architecture. My approach is pragmatic: I focus on the decisions that compound, the ones that make every feature easier to ship and every new team member faster to onboard.

Micro-Frontend Architecture for a Multi-Brand Platform

A large-scale platform serving multiple brands was running on a monolithic frontend. Teams were blocked by shared codebases, deployments were slow and risky, and scaling the engineering organisation meant stepping on each other's toes constantly.

  • Migrated platform to micro-frontend architecture with independent deployments
  • Adopted native web components for framework-agnostic shared UI
  • Enabled teams to ship features independently without cross-team coordination

Multi-Brand Blogging Platform on WordPress and React

Multiple brands within the organisation needed a modern, flexible content management and publishing platform. Existing tools were fragmented across brands with no shared infrastructure, making content operations slow and inconsistent.

  • Delivered a new blogging platform built on WordPress and React
  • Platform adopted across multiple brands for content publishing
  • Unified content management workflow for editorial teams

Enterprise Feature Flagging and A/B Testing Integration

Frontend teams had no standardised way to roll out features incrementally or run experiments. Releases were all-or-nothing, making it difficult to test changes with real users or roll back quickly when something went wrong.

  • Evaluated and integrated feature flagging across multiple frontend projects
  • Onboarded and trained frontend teams on effective feature flag usage
  • Integrated A/B testing tools enabling data-driven product decisions

Thinking about frontend architecture and the decisions that compound.

Component API Design: The Decisions That Compound

Every prop you add is a maintenance commitment. Every abstraction you choose shapes how engineers think about your UI. Here's how I approach component API design when the components need to work across teams, frameworks, and brands.

The Monorepo Migration Playbook

Moving from scattered repositories to a monorepo is one of the highest-leverage infrastructure changes a frontend team can make. It's also one of the easiest to get wrong. A step-by-step approach from someone who's been through it.

Design Systems at Scale: Governance Without Bureaucracy

The hardest part of a shared component system isn't building it. It's making sure it stays useful as teams grow. Here's how I think about governance that enables rather than restricts.
