Full-stack software engineer

Striving to build systems that stay fast and reliable.

Backend, performance and systems-minded engineering across the stack.

[01]

Selected work

Production problems, traced from symptoms to architecture.

Architecture / Performance2026

Geospatial job search

Tracing a production map search from lookup speed to startup behavior and query plans.

Scope
Backend / PostgreSQL / API / performance
Problem
A fast local index created warm-up and operational complexity.
Outcome
Database-backed queries with fewer startup dependencies.
Read engineering note
Mobile / Performance2026

Production mobile performance

Profiling startup, rendering and query behavior in a production React Native app.

System
React Native / Expo / TanStack Query
Focus
Startup paths, unnecessary renders and device-specific bugs.
Outcome
A key loading path improved from roughly 10 seconds to 4 seconds.
Agents / Infrastructure2026

Durable agent infrastructure

Coding-agent infrastructure built around recoverable execution.

Scope
TypeScript / XState / PostgreSQL / infrastructure / evaluation
Decision
Explicit state, bounded tools and durable checkpoints.
Outcome
Inspectable, reproducible and safer work on real codebases.

About

I write and build to make engineering reasoning inspectable.

I’m Mouhib Ben Nasser, a Tunisia-based engineer working primarily with TypeScript. I like following problems through the full request path—from the interface to the database and back.

That leads me toward performance, databases, distributed systems and developer infrastructure. I’m interested in full-stack and backend-leaning roles, and open to relocating to Germany.

About / Mouhib Ben Nasser

Full-stack software engineer with a backend, performance and systems bias. I can ship across the stack, and I am particularly valuable when something becomes slow, unreliable, difficult to scale or difficult to understand.
