Software & Security Engineer·Full-Stack Systems

Jugert Muçoimaj

I started in security engineering and now build whole products in Python and TypeScript: the API, the interface and the Docker file. If you have something interesting to build, I’d like to hear about it.

Things I’ve built

Produsera is a live product. The rest is open source on GitHub, shipped with docs, tests and a licence.

Produsera

Live Product

A CRM you assemble. The core covers customers, appointments, quotes and invoices; stock, purchasing, returns and accounting are modules a business switches on only when it needs them.

A multi-tenant product with a free core, paid modules, an audit log and Microsoft account sign-in. Each workspace gets its own Postgres schema.

.NET 9, Blazor, Postgres.

envless

AGPL-3.0

A self-hosted home for environment variables that keeps the connection open. Change a value and every running application has it about a hundred milliseconds later, with no restart and no deploy.

Built for the day a credential leaks: values are encrypted at rest, tokens are stored hashed, every write is versioned and audited, and a rotation shows which applications have not caught up yet.

FastAPI, Postgres, Next.js, server-sent events, Docker. AGPL-3.0.

XIFF

Pure Python

A small language for drawing with intent instead of raw SVG path commands. You say how long a stroke is and where it bends; the engine solves the geometry and writes a PNG. Pure Python, no dependencies.

maptiveui-tunable

npm package

A dev-only React wrapper, published on npm. Wrap a component, drag sliders in a floating panel, then copy the CSS or Tailwind classes back into your code. Try the idea here.

esign

Full-Stack Suite

An e-signature application in two repositories: a React and Vite front end, and a FastAPI service on Postgres with Alembic migrations, JWT sessions and Google sign-in.

React, Vite, FastAPI, PostgreSQL, Alembic, JWT, OAuth2.

Engineering Principle:

"Python is my primary hammer for backends and engines. Strict typing with Pydantic, zero unnecessary runtime dependencies, and async boundaries kept strictly isolated."

Background

I came up through information security engineering, with Cisco networking training behind it, and wrote business software on Odoo along the way. Both left habits: I assume a key will leak one day, I want a record of who changed what, and I like software that says plainly what state it is in.

Today I work across the whole stack. I’m comfortable owning a service from the database schema to the last pixel, and I write the README as carefully as the code.

Zero Trust

Assume secrets rotate; encrypt values at rest and hash tokens.

Audit Trails

Every mutation is versioned; deterministic and rollback-ready.

Plain State

No hidden magic; clean APIs, clear logs, and transparent state.
