My Projects

Kiz Platform

A developer platform built as a Kubernetes operator in Go (Operator SDK), with separate dev and prod stages. Teams define their DAOs, DTOs and CRUD, apply them with the kiz CLI, and Kiz provisions the databases and their relationships on PostgreSQL, MongoDB, ClickHouse or CockroachDB. Images are built and pushed to GitLab, every release shows up in the Kiz panel, and apps are deployed through a Forge with their environment and runtime config. Built in three months with AI tools and still evolving.

SadrChoob

End-to-end platform for a wood manufacturing factory: the public website, an installer app, and app.sadrchoob, one admin panel to run the factory, its installers and its workers. Built as a pnpm-workspace monorepo of connected apps (CRM, installer app, web API, customer ratings, analytics and CatMaster) that share their data and status in that single panel. React, Next.js, FastAPI and PostgreSQL.
