Projects & Highlights

Steevy Indie

Steevy Indie

As the solo founder, I single-handedly took a relaxing puzzle game from concept to a complete, live product. This involved building a custom puzzle-generation engine and engineering a high-performance graphics system. The project showcases my ability to manage the entire product lifecycle and leverage AI as a creative partner while applying deep expertise to solve complex challenges.

HTEco

HTEco

To serve a gaming community, I built a data analysis tool that interfaces with a legacy SOAP/XML API. I engineered a modern adapter layer to transform the data, re-architected the entire application to Deno/Fresh for improved performance, and implemented an intelligent pre-fetching strategy. This delivered a seamless user experience, turning the project into a stable, live product.

Hospital Information System (HIS)

Hospital Information System (HIS)

As a founding engineer and later team lead, I co-architected and built a robust Hospital Information System (HIS) from the ground up using a microservices architecture. The solution proved its resilience by successfully processing thousands of daily COVID-19 tests at peak times, and its architecture became the official blueprint for all subsequent large-scale company projects.

E-commerce Cross-platform App

E-commerce Cross-platform App

Tasked with rapidly extending an e-commerce platform to mobile, I researched and pioneered the implementation of a universal app architecture. By leveraging a monorepo with Next.js, Expo, and Tamagui, I architected the solution for maximum code sharing and established an automated CI/CD pipeline, laying a scalable foundation for future cross-platform development.

Work Experience

Independent Product Developer @ Personal Projects (Founder & Solo Developer)

After 5+ years of dedicated professional growth, I took a planned career break to pursue independent product development. This period was focused on building full-stack applications from concept to market, exploring human-AI collaboration, and deepening my expertise in modern web technologies.

  • Launched Steevy Indie: A mindfulness-focused puzzle game, single-handedly managing the entire product lifecycle from ideation, UI/UX design, and development to deployment, SEO, and marketing.
  • Re-architected HTEco: Migrated a full-stack application from a traditional React/NestJS stack to a modern Deno/Fresh architecture, solving complex legacy API integration challenges.
  • Mastered End-to-End Product Ownership: Gained hands-on experience in market research, product strategy, user analytics, and building automated content creation tools.
  • Deepened Technical Skills: Advanced my proficiency in React, Next.js, Deno, system design, and building high-performance, user-centric interfaces.

Full-stack Developer @ Sunny Development

Played a key role in the company's growth over 5+ years, contributing to a wide range of internal and client-facing projects. My responsibilities evolved to include system architecture, team leadership, and pioneering new technologies.

  • Architected Core Systems: Co-designed and developed the foundational microservices codebase that became the successful blueprint for subsequent company-wide platforms.
  • Led a Development Team: Led the team responsible for the critical Authentication & Authorization module, providing technical leadership and supporting other developers.
  • Engineered Complex Integrations: Successfully bridged modern RESTful services with legacy SOAP APIs to ensure seamless data flow for enterprise clients like Kidzania.
  • Pioneered Cross-Platform Solutions: Spearheaded the company's adoption of modern architectures by independently developing a cross-platform e-commerce app using a Monorepo.
