Premium Personal Expense Tracker

Full Stack

Velnora - Expense Tracker

A personal expense tracker that turns everyday spending into a clear picture. Log an expense in seconds, set a monthly budget, and import your spending history from CSV or Excel. Totals and category breakdowns show up on one calm, private dashboard. Built with TanStack Start, React, and Supabase, with row-level security so every number stays private.

  • Live dashboard with totals, six-month trends, and category charts
  • CSV and Excel import with column mapping, plus one-click filtered export
  • Supabase Auth and Postgres row-level security, so each user only sees their own data

Instagram-Style Backend API

Backend

Social Media Backend API

A modular social media backend built with NestJS, GraphQL, and Prisma. It covers the core of any social app: posts, likes, follows, notifications, and JWT authentication. A hotScore algorithm ranks the feed instead of just sorting it by time. The whole thing is structured as a clean modular monolith, built to stay easy to scale and maintain.

  • Modular NestJS monolith with GraphQL and Prisma
  • Posts, likes, follows, notifications, and JWT authentication
  • hotScore ranking, so the feed is never just a plain timeline

Headless Content Management System

Full Stack

MiniList - Headless CMS

A full-stack headless CMS with a modern Next.js admin dashboard and a scalable NestJS backend. It handles rich text editing, blog and author management, API keys, analytics, Google OAuth, and SEO tools. A REST API sits underneath for smooth content delivery. Built on Prisma and PostgreSQL, so it stays clean, scalable, and easy to self-host.

  • Next.js admin panel and NestJS API, built as a self-hostable headless CMS
  • Rich text, authors, SEO fields, API keys, and Google OAuth in one place
  • REST and GraphQL support, so each consumer can use the format it already speaks

Real-Time Group Chat

Full Stack

Real-Time Chat Application

A lightweight real-time group chat app built with WebSockets. It handles instant messaging, chat rooms, typing indicators, and seen status. The whole thing runs as a Turborepo monorepo, with a Next.js frontend and a Node.js backend. The result is a chat experience that feels fast, clean, and genuinely responsive.

  • Instant rooms, typing indicators, and seen receipts, all over WebSockets
  • Turborepo setup with a Next.js client and a dedicated Node.js socket server
  • Shared TypeScript types, so message shapes can't drift between frontend and backend
