About

Who I am:

I’m Mouhcine, a Senior Full-Stack Software Engineer with 10 years of experience building enterprise-grade web applications. I specialize in Java/Spring Boot on the backend and React/Angular/TypeScript on the frontend, and I hold an AWS Certified Solutions Architect – Associate certification. I’m based in Ottawa, Canada, and available for remote or hybrid engagements.

What I’ve done:

Over the past decade, I’ve delivered production software for some of the world’s most demanding organizations:

Rolex — Built and integrated RESTful APIs between manufacturing systems and web interfaces, led a zero-downtime migration from OAuth2 to Okta, and refactored legacy frontend/backend modules to cut the defect rate by 30%

Société Générale — Grew unit test coverage from 0 to 80% on legacy systems, modernized backend services, and mentored junior developers on TypeScript and React

AXA — Delivered core insurance web services and built a shared reusable component library that boosted team development productivity by 30%

BNP Paribas & Capgemini — Built digital banking features for major French financial institutions, including customer onboarding modules and portal redesigns that reduced page load times by 40%

What makes me stand out:

Enterprise pedigree in high-stakes domains — My work spans luxury goods (Rolex), banking (Société Générale, BNP, Capgemini), and insurance (AXA), so I understand security, compliance, and performance at scale

Full-stack depth, not breadth — I’m not a generalist who dabbles in everything. I go deep on both Spring Boot microservices and modern React/TypeScript frontends, so I can own a feature end-to-end

Cloud-certified and production-ready — AWS certification paired with hands-on cloud deployment experience means I can design and ship cloud-native solutions, not just talk about them

Fast integration into existing teams — I’ve consistently joined complex, large-scale codebases and delivered value quickly without needing a greenfield setup

Bilingual (FR/EN) — I communicate fluently in both French and English, a real asset for Canadian clients operating in both markets
