//full-stack engineer / lebanon

Khaled Saeedbuilds software that explains itself.

Known online as KhaledSaeed18. I design and build products end to end: interfaces people enjoy using, backends that hold up in production, and the tooling in between. Some of it ships with a team, some of it stays private, and some of it I give away. All of it gets the same standard: clear behaviour, honest errors, and nothing left for the next person to guess.

all 21 projects

Things I built because they should exist.

Platforms that keep tenants apart at the database, and Linux tools that show their evidence: where the battery went, what a link really does, which change broke the system.

experience

2 years 2 months on the clock.

Client work since Sep 2024, without a gap: an internship that turned into a developer's desk, then an engineer's. Every month of it is on the tape. The companies, the chapters and what was built are on their own page.

//03datasheet

The stack, pin by pin.

TypeScript end to end, Swift when it belongs on the Mac, and whatever the problem actually needs underneath.

features

  1. 01

    Make the wrong thing unrepresentable

    If a bug can be prevented by the schema, the type system or the database, it should never reach a code review.

  2. 02

    Boring infrastructure, sharp edges

    Pick proven tools for the foundation so the time goes into the details people actually touch.

  3. 03

    Legible software

    Tools should explain themselves: why a process would not die, why a Mac is awake, why a token is unsafe.

  4. 04

    Ship, then keep it working

    CI, security scanning and invariants you can run matter as much as the first release.

Microservices Solve a Problem You Don't Have

Somewhere right now, a three-person team is drawing boxes on a whiteboard. There is an auth-service, an orders-service, a notifications-service, a message broker between them, and an API gateway in front. The product has zero users. The team has never operated a distributed system. And every box on that whiteboard is about to become a repository, a deployment pipeline, a set of environment variables, and a production alert at 2 a.m.
