Our Team
Chun Wei Chen
Co-founder · Software Specialist
- Designs AI-powered tools — natural-language data queries, support agents, and automated code review — bringing practical, production-ready AI into everyday business operations.
- Leads the technical side of Proyecto HIS, Paraguay's national hospital information system, since 2020 — software relied on by roughly 30,000 healthcare workers and over 1.5 million patient visits every month.
- Modernized the system from a legacy monolith into a decoupled Next.js + Java platform, and its infrastructure from a single server to a highly available Kubernetes cluster — delivering the kind of large-scale upgrade that keeps a business running without downtime while it grows.
- Introduced the HL7 FHIR healthcare data standard so the system could securely exchange data with outside providers — adding new capability to a live, mission-critical system without disrupting the people who depend on it.
Yun Jie Zhang
Co-founder · Software Specialist
- Applies production-hardened engineering experience to designing custom software and AI-powered workflows for businesses.
- Led development and operations of hospital outpatient and emergency department systems across 93 servers in Paraguay, supporting more than one million patient visits every month — experience building software that can't afford downtime.
- Modernized the platform's frontend to Next.js while the system stayed in daily use by hospital staff, proving that legacy software can be upgraded without disrupting the people who rely on it.
- Built integrations with laboratory and medical imaging systems, letting clinical staff access lab results and images directly inside their existing workflow — the kind of system integration that saves real operational time.
