§ PROJECTS

Projects

Local AI English tutor
LocalTeacherGoOllamawhisper.cppPiperFFmpeg
detail
CLI to practise spoken English with an AI tutor. You type or talk and it answers back in text and out loud. Everything runs locally, with Ollama, whisper.cpp and Piper.
the hard part
Working with audio and models running locally. Building a CLI tool that works the same on every OS.
code →
Ticket queue system
wsTicketBunTypeScriptWebSocketReactZodTailwind
detail
Real-time ticket queues. WebSocket server in Bun, React frontend. Several screens see the same changes instantly, without refreshing.
the hard part
Working with WebSockets and real-time sync. Designing my own message protocol and validating all of it.
code →
Pastebin
SnippetSnippetGoMySQLHTMLCSSJavaScript
detail
Web app in Go to create and manage text snippets. User accounts, sessions in MySQL, server-side validation. Templates and static files embedded, ships as a single binary.
the hard part
Building by hand what a framework hands you. Go has no sessions, no middleware chain and no form validation, so you pick every piece and fit it yourself.
code →
Online store
Bulky-WebC#.NETASP.NET CoreEF CoreSQL ServerBootstrap
detail
A store built with ASP.NET Core and .NET 8. It has the customer catalogue and a separate admin panel where you load categories and products with their image. Accounts and roles come from Identity.
the hard part
Building a layered app with a generic repository and unit of work over EF Core. Handling authentication and roles with Identity.
code →
Country roulette
couldvebeenanywhereTypeScriptReactViteTailwindshadcn/uiD3
detail
It tells you how likely you were to be born in your country and then rolls again to give you another one, weighted by real population. Whatever comes up is shown on a map.
the hard part
Building a weighted random algorithm. Making maps that scale themselves to the size of each territory.
code →
Real-time chat
Basic-ChatRoom-with-SignalR-no-DBC#.NETASP.NET CoreSignalRJavaScriptBootstrap
detail
Real-time chat room with ASP.NET Core and SignalR. You pick a room, you type, and the message reaches everyone else instantly. It also announces when someone joins.
the hard part
Working with SignalR, a big library from the .NET ecosystem. Handling rooms and real-time broadcast.
code →
Web crawler
crawlerGogoqueryHTMLJSON
detail
Command-line crawler in Go. You give it a URL and it walks the pages of that same domain collecting links, images and text, and leaves everything in a JSON file. It runs in parallel with a cap.
the hard part
Scraping websites. Working with concurrency in Go, coordinating goroutines with mutexes and buffered channels.
code →
RSS aggregator
gatorGoPostgreSQLRSSsqlcgoose
detail
Command-line RSS aggregator in Go. You follow feeds, leave the loop running in another terminal pulling posts into Postgres, and read them with a command. Duplicates get filtered by URL.
the hard part
Writing SQL by hand and generating the data access layer with sqlc. Building a background process that decides what to fetch and when.
code →
URL shortener
linko-starterGoOpenTelemetryPrometheusGrafanaJaegerDocker
detail
URL shortener in Go, deliberately small. What matters is everything hanging off it. Structured logs with slog, metrics in Prometheus, traces in Jaeger and profiling with pprof.
the hard part
Instrumenting a whole service with structured logs, metrics, traces and profiling. Bringing the stack up with Docker Compose and reading it in Grafana. Learning what to look at to spot that something is wrong.
code →
Postman clone
Postman-cloneC#.NETWinFormsJSON
detail
Desktop client to test APIs, like Postman but minimal. You pick the method, paste the URL, it sends the request and shows you the response with the JSON indented. WinForms on .NET 8.
the hard part
Understanding the HTTP protocol from the inside by rebuilding a tool like Postman. Using WinForms to put together a desktop app.
code →
2D platformer
WhatVaniaUnityC#Cinemachine
detail
2D platformer in Unity. You run, jump, shoot, pick things up and move through levels, with score and lives that carry across scenes. Input System, Cinemachine and 2D tilemaps.
the hard part
Working with Unity and thinking in frames instead of request and response. Programming movement, enemies and state that survives between levels.
code →
AI job search
AIJobReactViteExpressZustandZodOpenAI
detail
Job listing search with AI-generated summaries. You filter, you page through, you open a listing and the summary shows up word by word while the model writes it. React with Vite and Express.
the hard part
Working with streamed responses from a model. Building the context it gets and putting a request limit on it.
code →
Shared map
wsMapsBunTypeScriptWebSocketReactMapboxZod
detail
Shared map in real time. You come in with a name and a colour, and everyone shows up as a marker the others watch move while you drag it. Server in Bun, map with Mapbox.
the hard part
Working with maps and coordinates in real time over WebSockets. Defining explicit contracts between the front and the back.
code →
Live vote count
political-partiesBunTypeScriptWebSocketReactChart.jsZod
detail
Live vote counting. You load parties, you vote, and the bar chart moves right away on every connected screen. Server in Bun with pub/sub, frontend in React with Chart.js.
the hard part
Working with charts that update themselves in real time. Building a whole CRUD over WebSocket, with no REST.
code →
