Replace a 90s ERP. Ship a real product.
Air freight forwarders still run their warehouses on HFSQL/MALTA3 — a Windows-only ERP nobody wants to touch. Malta is the ground-up replacement.
The brief was simple, the scope was not: rebuild the ERP as a modern multi-tenant SaaS — warehouse operations, IAM, mobile, customs, billing — and ship it as one coherent product.
I joined as front-end specialist. I ended up owning the design direction, the design system, the UX/UI of every module, and progressively contributing to the back-end.
DDD, hexagonal, Turborepo.
Seven apps share fifteen-plus packages — including a custom @malta/design-system. Boundaries are enforced via ESLint, not Slack.
Infra ships on Kubernetes (Scaleway), autoscaled with KEDA on SQS, observable through Grafana + OpenTelemetry, provisioned via Terraform.
50+ components, one voice.
The design system isn't a library — it's the contract that makes scale possible.
I built @malta/design-system before the first page was written: tokens, primitives, motion contracts, accessibility specs. The hardest part was enforcing reuse — every Sidebar, Sheet, OTP, Chart had to come from the system.
The result: a product that feels like one product, even with seven contributors shipping in parallel.
An assistant that ships actions, not just text.
Bill streams answers and triggers UI actions in the same breath. The conversation is the UI.
Bill runs on Groq + Llama 4 Scout with SSE streaming, rate limiting, and structured tool-calling. A user asks "Show transit shipments from CDG to DXB this week" — Bill streams the answer and updates the table filters in real time.

A warehouse app that lives in pockets.
Operators don't sit at desks. They walk racks, scan barcodes, sign papers. The mobile app is built for them.
Built on Expo + NativeWind, mirrored design system, one-handed UX, glove-friendly tap targets, offline-first. Released on the Play Store.
What shipped.
Beyond the front-end.
Malta forced me to stop thinking like a front-end specialist and start thinking like a product engineer. Lines blur at this scale — and that's the point. Owning the design system as a non-negotiable contract is what made it work.
