🚀 Building scalable backend systems & APIs

I’m currently available for projects involving backend architecture, API development, and SaaS platforms.

I specialize in building reliable backend systems using .NET, ASP.NET Core, PostgreSQL, and clean architecture principles.

Recent systems I've built include: • ChronoFlow – workflow orchestration platform • BeaconFlow – event ingestion API • SignalForge – signal detection engine • ClientForge – multi-tenant SaaS foundation

If you're building a platform and need help with API architecture, authentication systems, or scalable backend infrastructure, I'd be happy to connect and discuss your project.

I just published a case study on the SaaS I shipped on Replit to run my web agency end to end.

heyWebTeam Portal is a live multi-tenant B2B platform with 5 user roles (admin, account manager, project manager, team member, client), an 8-tab project workspace, real-time chat with WebSocket and read receipts, multi-currency PDF invoicing, hours packages, retainers, and AES-256 encrypted credential storage.

Stack: React + Vite + TypeScript on the front, Express + Drizzle + Postgres on the back, all on Replit.

Sharing the full breakdown for anyone curious what's possible on Replit past the prototype stage. Link in my profile.

Great job. React + Typescript always blend well together.

Hey, I’m Mostafa,

I build backend systems with .NET.

Anyone can build something that works locally… but that doesn’t mean it’ll survive real users.

I focus on building systems that are clean, scalable, and actually hold up under load.

If you're working on something serious, let’s connect.

Airship is a real-time engagement platform that uses APNs to deliver event-driven, stateful user experiences. It manages multi-stage lifecycles (pre-event, active, post-event) and continuously updates user-facing content through push-based triggers and scheduled workflows.

The system combines APNs updates, event processing, and time-based orchestration to keep user data in sync across a session.

This directly aligns with Apple Wallet requirements, where a pass or Live Activity needs to be updated dynamically over time via APNs, based on events like trip status, timing, and user activity.
