Full-Stack & AI Engineer Full-time Aug 2026 →

  • Part-time from 2024 alongside Luftborn (Wear&Care, Ventriject, MindPlus), then full-time from August 2026.
  • Qualihelp (qualihelp.com): Designed and built from scratch with AI agents a multi-tenant "branded AI" SaaS — one-script-tag embeddable assistant, per-tenant hybrid RAG (lexical + dense + RRF + rerank) with cited, streamed answers, draft-first knowledge versions, AI-authored skills, tenant-isolated MCP connectors, per-tenant AI cost metering and Stripe subscriptions.
  • Engineering rigor: .NET 10 + PostgreSQL/pgvector + NATS JetStream, Angular portals and a Lit widget on Kubernetes and Cloudflare Workers; tenant isolation proven by dedicated isolation, architecture and security suites (1,500+ automated tests), a 0-warning build gate and secret/SAST scanning in CI.
  • Privaci (privaci.io): Built a GDPR cookie-compliance SaaS — consent banner with Google Consent Mode v2 and IAB TCF v2.3, a Playwright scanner that finds trackers firing before consent, pre-consent tag blocking, Stripe billing and an agency portal.
Luftborn 2021 — 2026 Cairo, Egypt

Principal Software Engineer 2024 – 2026

  • Enterprise modernization (.NET 10 / Azure): Architected the modernization of eSignatur — a platform handling 1M+ signature orders — migrating .NET Framework 4.8 to .NET 10 with Aspire, introducing Event-Driven Architecture and moving RavenDB to MongoDB for a significant performance improvement.
  • Company-wide AI enablement: Co-led how AI is used at Luftborn — authored reusable AI "skills" for our .NET and Angular stack, including AI-assisted code review, now used by developers across the company.
  • Docs-generation plugin + git hook: Built a plugin that generates deep, cross-linked documentation for any repo — architecture, domain models, auth, deployment and ops runbooks — grounded in code actually read, and regenerates the affected docs on every push, keeping documentation continuously in sync.
  • SaaS leadership & identity: Sole technical lead for an internal HR & Recruitment SaaS (Modular Monolith + DDD) spanning recruitment, time-tracking, project management and invoicing — and sole owner of its identity solution, with OAuth 2.0 / OpenID Connect SSO via Keycloak.
  • System integration: Engineered a custom Windows Printer Driver for the Scrive platform using Win32 APIs and Worker Services, facilitating the acquisition of 3 major enterprise customers.
  • Technical consulting & mentoring: Advised a Unity project toward an investor-ready demo delivered in three weeks, and mentored 5+ interns to senior-level roles.

Senior Full-Stack Engineer 2021 – 2024

  • Full-stack feature delivery: Built features end-to-end across ASP.NET Core Web API services and Angular / TypeScript front-ends, turning mockups and wireframes into responsive, accessible UI.
  • Quality & reviews: Established unit-testing and code-review practices, delivering well-tested, defect-free code to QA; ran design and code reviews and partnered with Product Management on requirements and technical architecture.
  • Messaging & integration: Designed message-broker / event-driven integrations on Azure Service Bus to decouple services across the platform.

  • Ventriject (MedTech): Complete rewrite of a VO₂max measurement app from Xamarin to Flutter, with a custom BLE package for medical sensors.
  • Wear&Care (IoT / Elderly Care): Migrated a monitoring app from .NET MAUI to Flutter in a single week, improving stability.

Qualihelp — Branded AI Assistant Platform

qualihelp.com

Designed and built from scratch with AI agents: a multi-tenant SaaS where a company embeds its own AI assistant with one script tag and teaches it by uploading PDF, Word and Markdown files. Answers come from a per-tenant hybrid RAG pipeline (lexical + dense + rank fusion + rerank), streamed with citations, with draft-first knowledge versions, AI-authored skills, tenant-isolated MCP connectors, per-tenant AI cost metering and Stripe subscriptions. Built at bon.do on .NET 10, PostgreSQL + pgvector, NATS, Angular and a Lit widget — and it powers the assistant on this very site.

Salah Bahzad — Secure Learning Platform

mrsalahbahzad.com

A production education platform for a mathematics tutor: a role-based admin portal, a responsive student portal, and native Flutter companion apps for protected video — all on a .NET Clean Architecture / CQRS / DDD backend that's multi-tenant-ready by design. The hard part is the video: encrypted HLS (AES-128) with short-lived signed URLs and an in-player dynamic watermark, backed by OS-level screenshot & screen-recording black-out through the native apps' secure-surface flags — no paid DRM. Firebase-backed identity, a Redis real-time backplane, and an append-only, dispute-grade audit log round out the system.
