Jaxon (Tan Yue Jun)

Founder & Lead Full-Stack Software Engineer — JUX Technologies

I operate JUX Technologies as a focused, senior-led engineering studio. Backed by 8+ years of hands-on software development and portfolio showcased at tanyuejun.juxtechnologies.net, I bridge three disciplines that rarely meet in one person: Bespoke UI/UX Product Design, Cross-Platform Mobile Engineering (Flutter & Dart), and Scalable Full-Stack Architecture (React, Next.js, Node.js, Python, PostgreSQL).

When you hire JUX, there are zero account reps or junior handoffs. You collaborate directly 1-on-1 with me from technical architecture to live production release.

Why Solo Senior Works Better

Senior Craft Without Agency Bureaucracy

Traditional agencies charge $20k+ to pass your vision through 4 layers of middle management. Working directly with a senior builder unlocks unmatched momentum and precision.

💬

Direct Line Communication

One dedicated Telegram or Slack channel with Jaxon. Feedback and architectural decisions land directly in code without waiting for next sprint's planning meeting.

🎯

Design, Mobile & Backend In One Mind

I design the interface in Figma, build the mobile app in Flutter, and write the backend APIs myself. Zero handoff telephone games, zero lost details, and 100% architectural cohesion.

⚡

Built For Speed & True Ownership

Laser focus on one milestone at a time. Weekly interactive staging demos, transparent fixed pricing, and 100% full IP source code ownership transferred directly to you.

Philosophy

Three Rules I Build By

Principles that guide every software architecture, mobile app, and landing page.

🎯

Clarity Over Cleverness

Clean system architecture always beats convoluted spaghetti code. From intuitive user interfaces to typed API schemas, simplicity allows products to scale reliably without breaking.

⚡

Speed & Craft Are Features

A fast application builds immediate user trust. Whether it's a mobile app delivering 60fps animations or a web page loading in under 0.5 seconds, performance is never an afterthought.

🤝

Radical Accountability

I treat your software like my own startup. When your app launches smoothly, users sign up, and revenue flows, that is the only metric of success that truly matters.
