Angelo Zhang
Full-Stack Engineer · AI Product Architecture & 0-to-1 Delivery
I am a hands-on full-stack engineer and independent product builder focused on AI products. In recent work, I have owned the full path from product direction and user experience to system architecture, engineering execution, launch, and live operation.
My strongest work is turning ambiguous early ideas into working product systems: deciding what is worth building, shaping the boundaries, shipping the first version, and keeping the product maintainable as it evolves.
Rather than owning only one layer, I am most useful when a product needs one accountable builder across product judgment, full-stack execution, release quality, reliability, and feedback-driven iteration.
Before going independent, I spent five years as an Android engineer at Sogou, Qunar, and Ctrip. That consumer-app background still shapes how I think about stability, release discipline, performance, and product feel.
Core strengths
0-to-1 product delivery
Turns vague product direction into shipped, usable product surfaces with a clear path for iteration.
System-level architecture
Balances speed with long-term maintainability so systems can be launched, operated, and evolved.
Production ownership
Owns not only implementation, but also release readiness, recovery paths, feedback loops, and ongoing quality.
Consumer product craft
Carries mobile-era instincts for reliability, interaction quality, performance, and disciplined releases.
Engineering scope
Full-site architecture
Translates product goals into user journeys, application boundaries, data relationships, critical flows, release paths, and operating feedback.
AI product engineering
Turns AI capabilities into usable product experiences rather than isolated demos, API calls, or one-off features.
Full-stack execution
Moves from interface and interaction quality to service workflows, deployment, issue diagnosis, and continuous improvement.
Engineering discipline
Cares about access boundaries, reliability, release quality, and maintainability even when the product is still early.
Selected work
- LivelyVerseFounder · 2024 — present
A public AI product I took from product direction to launch and live operation.
- Own product positioning, user experience, system design, engineering delivery, launch readiness, and live operations.
- Compress complex capabilities into a product surface that is understandable to users and still has room to evolve.
- LeyLine ProFounder · 2024 — present
A second public AI product built with the same lean, independent 0-to-1 operating model.
- Moved from concept, pages, and core flows to public release as a solo engineer-founder.
- Use real feedback to refine positioning, interaction details, product boundaries, and delivery quality.
Experience
- 2024 — PresentIndependent Engineer · Founder— Self-employed
Building and operating public AI products independently, with full ownership from product definition and system design to live service.
- Shipped LivelyVerse and LeyLine Pro from blank slate to public websites and usable product surfaces that external viewers can inspect.
- Own product, design, engineering, launch, support, and iteration without a large team, turning early ideas into operated products.
- Prioritize durable quality, clear boundaries, disciplined releases, and real feedback over one-off technical spectacle.
- 2018 — 2023Independent Product Engineering— Various projects
Expanded from mobile specialist into full-stack product engineering across product, interface, service, deployment, and operation.
- Built the breadth needed to connect product judgment, interface implementation, service workflows, deployment, and operating feedback.
- Developed a pragmatic builder style: small releases, direct feedback, clear tradeoffs, and ownership of the final outcome.
- 2015 — 2018Senior Android Engineer— Qunar · Ctrip
Worked on mature consumer travel applications where reliability, performance, and release quality mattered.
- Delivered Android product work in cross-functional environments with strong QA and release expectations.
- Built long-term instincts for production stability, performance, and polished mobile interaction details.
- 2013 — 2015Android Engineer— Sogou
Started professional engineering career building consumer Android application features.
- Learned to ship within established product and engineering standards early in a large-company environment.
