What I do best in Backend

Where I go deepest: the systems that must stay correct under load, and the libraries that keep them consistent.

Backend & systems

Expert

The engine room — reliable production back-ends across three technology ecosystems, plus the shared packages that keep large, multi-part systems consistent as they grow.

  • Peer-to-peer sync — outbox/inbox, signed-webhook transport, conflict resolution, schema fingerprinting
  • Replicated storage — primary-first writes, write-buffer fallback, ordered reads, periodic reconciliation
  • Six-plus years of production delivery across Laravel, .NET, and FastAPI
  • Laravel
  • .NET / C#
  • FastAPI
  • PostgreSQL
  • Redis

Library & API design

Expert

My signature — drop-in libraries with clean APIs that add capability to a product without taking over its architecture, built across .NET and Laravel.

Developer experience & platform

Expert

Tooling and automation that manufacture a whole configured environment reproducibly — the kind of leverage a team feels every day after.

Also strong across

One source of truth, routed to the role. Same résumé, focused on a different stack.

Selected work

Open source — real names

Composable .NET library ecosystem (opens GitHub in a new tab)

A cohesive family of drop-in packages plus a generator that scaffolds production-ready projects — adding capability to a codebase without taking over its architecture.

  • .NET
  • Libraries
  • Developer tools

Workstation-bootstrap engine (opens GitHub in a new tab)

An engine that turns a bare machine into a fully-configured developer workstation, unattended, in minutes — the clearest single expression of systems that generate systems.

  • Platform
  • Linux
  • Automation

AI agent orchestration & QA tooling (opens GitHub in a new tab)

Multi-agent tooling that implements and independently verifies software — parallel delivery with quality gates, distilled from real work that cut delivery time substantially.

  • AI agents
  • Automation
  • Quality

Personalized Python-mastery platform (opens GitHub in a new tab)

A learning platform that teaches Python to experienced builders — in-browser execution (Pyodide), AI-narrated lessons, and a constitution-first curriculum. Pedagogy encoded as software, AI woven through.

  • Learning platform
  • AI
  • TypeScript

Enterprise — anonymized · brands withheld, named on request

Technology-governance platform

An integrated governance system aligning IT operations to COBIT 2019, ISO 9001/27001 and ITIL 4 — controls, audits, risk and compliance workflows in one platform. Architect & lead engineer.

  • Governance
  • Compliance
  • .NET

Software-licensing infrastructure

A two-sided .NET system for licensing self-hosted, Docker-stack products — a vendor authority that issues activations, syncs configuration and tracks hardware-fingerprint drift, paired with a brand-agnostic single-binary field control panel.

  • .NET
  • Licensing
  • Distributed systems

Distributed-systems packages (Laravel)

Packages that keep multiple Laravel instances consistent across heterogeneous infrastructure — outbox/inbox, signed-webhook delivery, conflict resolution and a replicated filesystem driver with reconciliation.

  • Laravel
  • Distributed systems
  • Sync

Customer-support SaaS

A complete support product — embeddable widget, Filament admin backend, Astro marketing site, and an open-source framework plugin as the integration point. Architect & author.

  • SaaS
  • Laravel
  • Product

How I work

On the back end I optimize for leverage — the shared package or generator that makes the next service correct by default, not the one-off that ships Friday and rots by spring.

  • Technical lead of a software studio — the delivery, and the tooling beneath it.
  • Carry library-design taste across three ecosystems; earn abstractions from real, repeated delivery.
  • Build culturally-grounded products for MENA and Sudan, alongside open source.
