02. Portfolio

Fin App

On hold · testable 2024 — 2025

Full-stack personal finance system — wallets, credit cards, installment charges and expense splitting — built with .NET 9 + Angular 20, multi-tenant, with self-hosted containerized deploy and CI/CD.

Full-stack personal finance management app: wallets, bills, credit cards with installment charges, categorization, financial institutions and expense splitting between people. The backend follows Clean Architecture in .NET 9 (multi-tenant, PostgreSQL, Redis, background jobs with Hangfire, real-time notifications via SignalR) and the frontend is Angular 20 with standalone components and PrimeNG. The demo runs on self-hosted Docker containers, with CI/CD via GitHub Actions and a cloud reverse proxy — no third-party PaaS required to run.

Technical highlights

Backend .NET 9 in Clean Architecture (Domain / Application / Infrastructure / Api), multi-tenant.
PostgreSQL + Redis + MongoDB, recurring jobs with Hangfire, real-time notifications via SignalR/WebSocket.
Angular 20 frontend (standalone components, PrimeNG, i18n in 3 languages).
JWT + Google OAuth authentication and encryption of sensitive data.
Self-hosted Docker deploy (no PaaS), CI/CD pipeline via GitHub Actions, reverse proxy + Cloudflare.
Public demo mode designed with security in mind: no real e-mail sending and automatic daily cleanup of test data.

Fleet Availability @ Gestran

Corporate work 2025

Real-time fleet visibility module on Gestran's platform — current vehicle position on the map, live operational status and incident tracking.

Module of Gestran's fleet management platform that consolidates tracker data and external integrations to give customers full operational visibility: it shows each vehicle's current position on the map, records vehicle status in real time and tracks incidents during the trip. I was the developer responsible for the code (backend .NET 8 + Angular 18 frontend, EF and external API integration), including the map screens.

Technical highlights

Backend .NET 8 with Entity Framework and integration with external tracking APIs.
Angular 18 frontend, including the map screens with real-time vehicle position.
Live operational vehicle-status recording and trip incident history.
