Full-stack / AI Application Engineer

More than a decade in software delivery. I bring model capabilities into real products—controlled, testable, and ready for production.

01 / SELECTED WORK

Let real systems show the work.

One project demonstrates full-stack product delivery; the other demonstrates AI workflow design. Together, they define my engineering direction.

PROJECT 01Visit product

LinkAtlas

A privacy-first personal bookmarking workspace

Delivered from product definition through production deployment. Google and GitHub identities keep separate data spaces, with core data stored locally in SQLite.

Scope

Product, frontend, backend, identity, data, testing, and deployment

CM Workflow

A specification-driven AI development workflow

Turns an ambiguous request into reviewable specifications, implementation tasks, independent review, tests, and browser-QA evidence. The focus is making work inspectable, recoverable, and resumable.

Scope

Product method, agent roles, Skill boundaries, testing, and recovery

02 / CAPABILITIES

Problems I can help solve

Stacks change. I focus on whether a system can keep working under real constraints.

01

AI application engineering

Model integration, agent workflows, structured outputs, tool boundaries, human confirmation, failure fallback, and result validation.

AI can participate in real work without becoming unmanageable.
02

Full-stack product delivery

From interaction design, APIs, identity, and storage through containerization, HTTPS, backups, migrations, and production validation.

Comfortable crossing product, frontend, backend, and deployment boundaries.
03

Engineering reliability

Automated testing, browser QA, dependency boundaries, performance, and observability—using execution evidence instead of assumptions.

Every delivery can be reviewed, rolled back, and resumed.
03 / PATH

From engineering depth to complete products.

I started with Java and enterprise delivery. Today I bring the same quality standard to full-stack products and AI applications.

04 / EXPERIMENT

An experiment still has to run the whole chain.

An improved multimodal toolchain based on an open-source project. From semantic preflight and stroke planning through Canvas rendering, video encoding, and human acceptance, generating a file is not treated as completion.

Share the judgment, not just the result.

Notes on AI applications, product delivery, and engineering reliability—starting from a job-search portfolio and growing into a public body of work.
