Building software that scales businesses forward
I partner with startups and enterprises to design and build custom software solutions — from system architecture to shipped product. Currently crafting tools for non-profits and building Codyssey.dev.
What I've Built
Codyssey.dev
An educational platform helping software engineers learn to build and maintain long-term software products — not just ship quick demos and prototypes. Real-world architecture, design patterns, and production-grade practices.
Non-Profit Fundraising Platform
Designed and built a full-suite fundraising, CRM, and marketing platform for a US-based non-profit, enabling organizations to manage donors, run campaigns, and track engagement at scale.
iGaming Platform with Blockchain
Built internal packages and integrated blockchain/Web3 services for an iGaming platform, working with Symfony to deliver new features and third-party integrations.
Healthcare Web Application
Developed and optimized REST API endpoints for a medical web application, improving existing code performance and writing comprehensive feature tests.
Community Social Network
Built REST API and GraphQL features for a community social network, including third-party integrations, UI components, and test-driven development with full-stack Laravel and Vue.js.
Enterprise Entertainment Platform
Worked on an enterprise entertainment app with Elasticsearch, Redis, and caching layers — improving performance, reviewing code, and mentoring interns.
Enterprise Financial Application
Led a team of developers and QA engineers on a US-based financial application, driving architectural proposals, code reviews, and REST API development.
