Web developersystems builder
I turn operational complexity into software people can actually use — from enterprise platforms and data-heavy workflows to automation tools and independent products.
Based in Montreal. Working across product engineering, databases, delivery systems, and technical operations.
Four systems, surface to core
Enterprise platforms, delivery machinery, and an independent product — each shown from two sides: what people use, and what makes it dependable.
Where product meets operations
I build software at the point where product experience, enterprise data, and operational reliability meet. For the past four-plus years at Jesta I.S. I have built and supported enterprise Oracle systems and the internal tooling around them — combining day-to-day schema, PL/SQL and patching work with hands-on development of the web, desktop and automation tools that make those workflows livable. A recurring theme: modernizing 20-year-old legacy systems with incremental, non-disruptive tooling rather than rip-and-replace. I own features end-to-end: database design, backend services, production UI, and the delivery pipeline that ships builds to clients.
The system is the product
A clean interface over a fragile pipeline fails users eventually. I design the data model, the integration boundaries, and the failure states with the same care as the screen.
Boring reliability beats clever fragility
Idempotent scripts, rollback paths, version-control headers, visible drift. Delivery mechanics should be dull, auditable, and repeatable.
Working range
- Product & frontend
Interfaces for dense operational data — dashboards, admin tools, mobile flows.
React 18 · Next.js · TypeScript · React Native / Expo · Responsive UI · MUI v5
- Backend & APIs
Services that sit between users and enterprise data, tuned pools and caching included.
Node.js · Express · REST APIs · FastAPI · JWT auth · node-oracledb · knex.js
- Databases
Design, delivery, and administration — plus the change-management discipline around it.
Oracle 11g–19c · PL/SQL · SQL · PostgreSQL · Schema design · Grants & synonyms · Query optimization
- Delivery & cloud
Pipelines, artifacts, deployment to on-prem and cloud, identity integration.
Azure DevOps · CI/CD · Azure Service Bus · Entra ID / MSAL · IIS · Windows Server · Git
- Automation & operations
The unglamorous tooling that keeps environments known-good and teams informed.
PowerShell · Python · Monitoring dashboards · Alerting · Drift tracking · Teams webhooks
- Applied AI tooling
Production AI assistance with strict structure and human review — not chatbots.
Anthropic Claude API · Schema-constrained outputs · Validation pipelines · Prompt engineering
Have a system that needs a surface — or the other way around?
The project brief takes a few minutes and gives me enough to respond with something useful, not a form letter.
