AI Product Engineer
I build AI products that can survive reality.
AI Product Engineer with 10+ years across frontend and full-stack product delivery. Today I work on real product systems, and outside work I keep building independent projects to deepen my AI practice.

Work and independent projects
Profile
Product-minded AI engineering with public proof.
Proof, in public
Professional work and independent builds live next to each other here on purpose. Together they show the direction I am pushing toward: product-minded AI engineering with real constraints, clean execution, and public proof.
Independent2025
Fotelik
Extraction, scoring, vector search, and explainable AI inside one independent product.
Independent2025
4cast
Zero-to-one full-stack build with product scope, auth, admin tooling, QA, and AI-assisted delivery discipline.
Selected work
Work and independent builds that show the direction clearly.
The strongest signal is not one perfect case study. It is the combination of shipped work, AI product systems, and independent builds that make the transition legible.

Fotelik
Architect and Full-Stack Product Engineer
Extraction, scoring, vector search, and explainable AI inside one independent product.
AI-powered political matching product built around extraction, scoring, retrieval, and explainability.
Primary proof
- Built a custom quiz and matching engine for a voter-facing product, including state, scoring, and results UX.
- Created an AI-assisted pipeline that turned public political content into structured topic summaries and standardized answers.

Waku
Product Engineer
AI image product work centered on monetization, prompting, streaming UX, media pipelines, and the delivery systems around them.
Primary proof
- Implemented Stripe-backed credits and subscription logic for AI image generation, including entitlement checks and balance UI.
- Added authorization and overage-confirmation flows around streamed image generation and low-credit handling.

Common
Senior Frontend Engineer
Senior frontend role focused on making a complex production platform easier to change, safer to ship, and less burdened by legacy paths.
Primary proof
- Planned and implemented the first structural phase of a large frontend refactor with new shared and feature boundaries.
- Built the migration safety net with component harnesses, contract tests, Playwright refactor coverage, and CI guards.

Supporting proof
Experience and formal context behind the current direction.
The portfolio should lead with projects, but the background still matters. This is the delivery history and structured learning that support the move toward AI product engineering.
Experience
Delivery history that supports the current direction: product work, refactors, AI systems, and the engineering judgment behind them.

Writing and ongoing builds
Writing, AI Digest, and the systems I keep building.
Three lighter signals around the shipped work: public writing, recurring synthesis, and the workflows that keep turning rough ideas into reusable systems.
Writing
Selected essays
2 featured here
A deliberately small editorial layer: long-form essays on applied AI, trust, and production delivery, selected to show judgment rather than volume.
AI Digest
Daily digest
5 latest issue
Recurring synthesis from raw sources into a public artifact: technical signals, source links, and structured takeaways for AI engineering work.
Latest digest
Daily AI Eng Digest (2026-03-13)
