The architect of Hazenfield — and the reason there's a workshop here at all.
View full résumé →I architect the whole of every project we take on — the data models and APIs underneath, and the interfaces people actually touch on top. I work end to end: Odoo, Django, FastAPI and Flask on the server; Vue, Nuxt, Next.js and React Native on the front.
The seams are where I'm most careful — where front-end, back-end and infrastructure meet. I hold the line on type-safety, transactions and tests, so the surface stays calm because the structure underneath is sound.
Over the last few years that has meant architecting B2B marketplaces, multi-tenant SaaS, multi-cloud platforms and full ERP estates — from MySpecialist's twenty-odd Odoo modules to Rebound's forty-five, Exiqtive's Postgres row-level multi-tenancy, and Procell's Terraform-managed AWS and GCP estate. I founded Hazenfield to do this kind of work with two people I'd trust with any codebase.
Toptal puts every applicant through a multi-stage technical screen and accepts roughly the top 3%. Here's the live badge — the “Hire me” link goes straight to my résumé there.
A handful of platforms I architected.
A Belgian SaaS marketplace that pairs customers with vetted independent specialists, across Belgium and Switzerland. Inherited in 2022 as a Symfony tier on Odoo 8 — rebuilt as clean Django on Odoo 16, and run by the same three engineers ever since.
A multi-tenant workforce-management SaaS — Django + DRF backend, React frontend, Terraform-managed AWS. We've held the CTO chair since 2023, architecting all three layers and growing the engineering team into the system as it scaled.
A multi-stack platform for a US aesthetics and treatments company — an Odoo 18 ERP, a Next.js website on AWS, Lambdas for UPS shipment tracking and link verification, GCP Cloud Run services for OpenAI verification pipelines. We own the seams: the AWS Terraform estate, the serverless integrations, and the QA load testing.
An Odoo 19 platform that runs the company end to end — sales, CRM, HR, projects, treatment, cashflow, GAAP audit. Forty-odd custom modules, a nightly Playwright regression on AWS, and the first project where the three of us hold distinct seats: Dan on architecture and DevOps, Dina on Odoo modules, Hasina on test automation.
A five-surface platform we built for our own congregation — an Odoo 19 administrative board with the Madagascar accounting localisation we had to ship to make it work, a public Vue 3 website, a Flask + Nuxt 3 cockpit for the worship team, and an Expo companion app for the congregation. Five stacks, one community, made with gratitude.
