MSc Student | BSc in Software Engineering

I like working with code to build well-structured software.
Outside of coding, I enjoy exploring game bioopment — I've built a few games, including Slime Adventure. It is a fun, different way to approach programming.

About

Ever since I was young, I've had a strong passion for computers and technology — a curiosity that led me to competitive programming at the very beginning of high school.
I continued this journey at LUT University in Finland, where I completed my Bachelor's degree in Software and Systems Engineering in the summer of 2026. Today, I'm a first‑year Master's student in Digital Systems and Service Development at LUT, focusing on how full‑stack systems are designed, integrated, and delivered as real products.
Outside of coursework, I like building things end to end — from web applications to small games in Godot — and I'm always looking for the next problem worth solving. Please feel free to get in touch with me here.

Keys2Balance Oy

Web Developer
Dec 2025 — May 2026

Remote | Hämeenlinna, Finland

Worked in a 9-person Agile/Scrum team to build Keys2Balance's full-stack Learning Management System (LMS) from scratch across 6 sprints, supporting 150+ users across Admin, Trainer, and Participant roles.
- Developed end-to-end functionality using React/Redux and Node.js/Express, implementing 44 REST API endpoints backed by a PostgreSQL database with 10 entities.
- Used Git/GitHub for version control, collaborative development, and code reviews, and contributed to production deployment on Fly.io.
- Led frontend tutorials and reviewed teammates' code, helping maintain consistent project structure, coding practices, and code quality.

Self Project
Jul 2025

Self-directed

Built and deployed a full-stack project management app with React, Express.js, and MongoDB, featuring 21 REST API endpoints across 4 collections and JWT-based authentication.
- Implemented project, category, and task management with priority levels, sorting, completion tracking, and a dashboard showing overall progress.
- Developed 8 routes with 36 React components and Redux Toolkit state management, supporting 3 languages (English, Finnish, Vietnamese), and deployed with Docker on Fly.io.

Slime Adventure

Self Created Game
Jul 2026

Self-directed

Designed and built a 2D action-survival platformer solo in Godot 4 (~3,000 lines of GDScript, 39 scripts, 32 scenes), with 2 playable characters, local 2-player mode, and endless wave progression across 2 difficulty modes.
- Trained a reinforcement-learning enemy-chase agent in Python (Stable-Baselines3) with an 8-feature observation space and a custom shaped reward, then integrated it into the game via ONNX to drive enemy pathfinding.
- Implemented 3-hit combo combat with damage scaling by combo step and player level, XP-based leveling, and platformer physics including multi-jump, knockback, and breakable chests.
- Built a wave system where enemy count grows 40% per wave and enemy HP scales each wave, with weighted chest loot (coins, HP, shield, speed boost) and a coin shop for permanent damage upgrades.
- Added persistent save data for high scores and settings, and took the project from concept to a playable public build on itch.io.

Blog App Website

Self Project
August 2026

Self-directed

Built a full-stack blog-sharing platform with Next.js 16, React 19, TypeScript, and PostgreSQL (Neon) via Drizzle ORM, covering authentication, blog publishing, likes, user profiles, and personal reading lists across 9 routes.
- Designed a 3-table relational schema with foreign-key constraints and evolved it through 8 versioned Drizzle migrations; implemented 6 type-safe server actions covering blog creation, likes, and reading-list management.
- Secured the app with NextAuth credential login (JWT sessions) and bcrypt password hashing, plus server-side form validation and session checks on every protected action; added a Bearer-token REST endpoint with per-user API tokens.
- Wrote 28 Playwright end-to-end tests across 4 suites, covering registration, login, blog CRUD, filtering, and reading-list flows, and automated them in a GitHub Actions CI pipeline that runs on every push and pull request.
- Styled a responsive UI with Tailwind CSS v4 and added case-insensitive blog search.
