Miro Mariapori
Full-stack Software Developer | TypeScript, React & Node.js
Summary
Software developer with hands-on experience in React, TypeScript, Node.js, GraphQL, and database-backed applications. My strongest proof of work is the 15-month GameRAT research project, where I was responsible for all web development and built the frontend, backend, authentication, 3D exercise editor, movement-data processing solutions, and a neural network for physiotherapy movement analysis. I am open to software development roles throughout Finland and willing to relocate.

Work experience
Software Developer
Helsinki XR Center • 1/2024 – 3/2025
- Solely responsible for all web development in the 15-month GameRAT research project as part of a four-person multidisciplinary team
- Designed and implemented the React frontend, Node.js/GraphQL backend, MongoDB data model, JWT authentication, and role-based access control
- Built a Three.js 3D exercise editor and the Quest 3 movement-data processing and analysis pipeline
- Designed and implemented a neural network for a proof of concept in detecting incorrect physiotherapy movement, plus the backend that received its training data
- Handled server deployments and data protection, including backend-only database access and AES encryption for stored patient-related data
- In user testing by physiotherapists, the web system was found functional and sufficiently easy to learn
Project-based
Freelance Software Development • 8/2022 – Present
- Completed six smaller client projects, including websites, WordPress solutions, automations, and integrations
- Built a Python Telegram bot for CSV data processing as well as WordPress/PHP solutions
- Independently handled requirements, scope, implementation, and delivery for small assignments

Projects
Gamified Joint Rehabilitation, Analysis and Training (GameRAT)
- Solely responsible for web development as part of a four-person multidisciplinary team; implemented the React/Three.js interfaces, GraphQL backend, authentication, and MongoDB data model
- Designed and implemented a neural network for detecting incorrect physiotherapy movement and the backend that received its training data
- Implemented the Quest 3 movement-data pipeline, Unity APIs, AES encryption, and server deployments
Route Management System for an Autonomous Tracked Articulated Vehicle (thesis)
- Built a React/Leaflet and Node.js/WebSocket thesis system for route creation, command routing, and monitoring of an autonomous tracked vehicle
- Implemented a vehicle simulator, vehicle-specific command routing, and a lost-connection stop behavior as a foundation for later integration
- Communication was integrated as far as the vehicle computer, but the system was not yet deployed end to end in the actual vehicle during the thesis
TKIO-Finder
- Built a working full-stack demo for Metropolia as the client to improve discoverability of RDI project positions
- Implemented PostgreSQL models, search, filters, Google OAuth2, role-based access, mutual matching, and private-server deployment
