01 — about

One-person studio, full-stack depth

I'm Aymen — a full-stack engineer with 15+ years building for the web (fintech, SaaS, enterprise), and the last few years focused on one thing: putting AI to work inside real products.

My background is deep in the enterprise stack — .NET Core services, Angular and React frontends, data-heavy dashboards — and that foundation is exactly what modern AI products need: someone who can take an LLM beyond the demo stage and wire it into production systems with proper APIs, auth, observability and a UI people actually enjoy using.

Today I work like a one-person studio: product thinking, design sensibility and engineering depth, from idea to deployed product.

Design, code & intelligence

01

AI Engineering

core focus

The interesting problems are in the integration: grounding models in real data, giving them tools, and making the experience feel instant.

  • LLM integration (Anthropic, OpenAI)
  • RAG & vector search
  • Agents & tool orchestration
  • Prompt design & evals
  • Streaming AI UX

02

Product Design & Frontend

Interfaces that feel considered — type, spacing, motion — built on modern component architecture that scales.

  • Next.js / React 19
  • Angular
  • TypeScript
  • Tailwind CSS
  • Motion & data-viz

03

Backend & Cloud

Reliable services behind the pixels: APIs, data models, auth and delivery pipelines that don't wake you up at night.

  • .NET Core / C#
  • Node.js
  • PostgreSQL / SQL Server
  • Vercel
  • Azure
  • Docker & CI/CD

04

Mobile & Cross-Platform

One codebase, every pocket — hybrid apps with native feel, from early Android Wear experiments to modern Capacitor builds.

  • Ionic / Capacitor
  • PWA
  • Android (incl. Wear)

04 — journey

From web roots to AI products

15+ years across fintech, SaaS and enterprise — tap a role to see the details.

    • ✦Core engineering on the embedded-payments platform (accounts, cards, payments) built by Natixis Payments with Visa.
    • ✦.NET Core microservices, REST APIs and event-driven flows on the backend; large Angular applications on the front.
    • ✦Championing AI inside the SDLC: LLM-assisted development, retrieval over internal knowledge and agent tooling.
    • ✦Banking-grade non-functionals: security, compliance, observability and CI/CD pipelines.
    • ✦Full-stack development on payments and banking web platforms within Groupe BPCE.
    • ✦C# / .NET services paired with Angular frontends, delivered to enterprise standards.
    • ✦Part of the team journey that spun up Xpollens, the payments-in-a-box venture launched with Visa.
    • ✦Consulting mission for the French environmental-services and recycling group.
    • ✦Enterprise operations tooling across the .NET stack — from data model to UI.
    • ✦Owned product and technical direction as part-time freelance CTO.
    • ✦Architecture decisions, delivery pipeline and hands-on development when it mattered.
    • ✦Four years on the sustainability-ratings SaaS used by procurement teams and global supply chains.
    • ✦End-to-end .NET web platform work: backend services, data-heavy screens and UX improvements.
    • ✦Led .NET development across products such as SmartMaint, SmartPlan and SmartRfid.
    • ✦Hybrid Ionic/Angular mobile apps and UX/UI design — the foundation of the full-stack + design profile visible on my Behance.
