Design. Build. Ship.
I build modern web applications end to end — clean interfaces, reliable backend systems, REST APIs that other teams can depend on, and AI-powered features that solve a real problem.

See what I doTurning complex ideas into practical software.
I'm Hassan El-Deghidy, a full-stack web developer with a strong focus on frontend engineering and building modern, scalable web applications.
My work covers the whole path: clean interfaces on the front, reliable backend services and data behind them, and the APIs in between. I care about how a system is put together, not only whether it runs — clean code, thoughtful architecture, and performance are part of the brief, not an afterthought.
Outside client work I'm active in open-source development and in exploring new technologies, especially AI-powered systems. I'm always glad to collaborate with developers, startups, and agencies on products that are worth building.

What I work on
Five areas I take projects in. The cards come from data, so named projects and links can be added without touching the layout.
-
AI-Powered Systems
Model integrations, memory, and automation workflows.
AI-powered applications and the infrastructure under them: model integrations, memory systems, multi-provider architectures, and automation workflows that run without a human watching every step.
- TypeScript
- Node.js
- LLM APIs
- Python
-
Trading & Financial Systems

Algorithmic trading infrastructure written in Rust and Python, focused on risk management, execution workflows, exchange integrations, and the kind of reliability that financial software does not get to compromise on.
- Rust
- Python
- REST APIs
- WebSockets
-
Cloud & Web Applications

Modern web applications and cloud-based services, from file management and storage solutions to API-driven platforms that other products build on top of.
- Next.js
- Node.js
- MySQL
- MongoDB
-
Developer Tools & Infrastructure
CLIs, utilities, and automation that speed up the work.
Developer-focused tools, command-line applications, software infrastructure, and automation utilities designed to take friction out of ordinary development workflows.
- TypeScript
- Node.js
- Python
-
Open-Source Development
Contributions focused on quality and maintenance.
Contributing to and working with open-source projects, with attention on code quality, maintenance, functionality, and the unglamorous improvements that keep a project usable.
- Git
- GitHub

How I can help
Taken as a whole project or as the one piece you are missing.
-
Full-Stack Web Development
Complete web applications, from the frontend interface through backend services and the database underneath.
-
Frontend Development
Responsive, modern interfaces built with React, Next.js, and the current frontend toolchain.
-
Backend Development
Scalable backend services, APIs, authentication systems, and database integrations.
-
API Development & Integration
REST APIs built from scratch, and applications connected to third-party services and external platforms.
-
Maintenance & Bug Fixing
Diagnosing and resolving technical issues, improving performance, and keeping existing applications healthy.
-
AI API Integration
Integrating AI models and intelligent services into existing applications and business workflows.
How I work
The standards the work is held to, from the first commit to the handover.
-
01
Maintainable by default
Clean, maintainable, and reusable code. Six months from now, someone should be able to read it and change it without a struggle.
-
02
Built to scale
Scalable and reliable software, sized for the load that is coming rather than only the load that is here.
-
03
Structured delivery
Structured development practices: clear scope, sensible milestones, and work that can be reviewed as it progresses.
-
04
Performance and security
Both treated as requirements rather than optimizations to attempt later, once something is already in production.
-
05
Practical architecture
Architectures designed to be maintained by a small team, not admired from a distance.
-
06
Clear communication
Maintained throughout the work: what is done, what is next, and what is blocked, without having to ask.
Agencies, startups, and remote teams
Freelance projects, long-term partnerships, and ongoing maintenance — whatever shape the collaboration takes.
-
Agencies
Extra capacity on agency builds, white-label and unbranded.
Software development and digital agencies bring me in when a project needs a full-stack developer behind it. The work goes out under your name.
- White-label development
- Overflow capacity on existing projects
- Frontend or backend, as the project needs
-
Startups & SaaS
From an unfinished idea to a product in front of users.
Early-stage teams where the same developer has to move between interface, API, and database. I build the version that gets you to market and holds up past it.
- MVP to production application
- API design and third-party integrations
- AI features where they earn their place
-
Businesses & Remote Teams
Ongoing development, maintenance, and technical support.
Businesses that need a dependable developer on call rather than a full-time hire, and remote teams that need someone who answers questions plainly.
- Long-term development partnerships
- Ongoing maintenance and support
- Remote contract and part-time work
