Full-stack product engineer
Efe Genc
I'm a full-stack product engineer building early-stage, AI-native products across web, mobile, backend and the AI product layer.
I take underspecified problems from product definition and architecture through implementation, rollout and production verification.

Six systems, stated precisely
LILA
A proactive AI assistant whose hardest problem is not generating more but knowing when not to speak, enforced by a twelve-check delivery gate that decides whether, when, and to whom a signal should actually reach.
Open-source tools
Five packages that make my private-repository methods public and reusable: product-engineer (an agent skill that makes coding agents explain every change to the customer), proactive-gate (LILA's twelve-check delivery gate as a library), workproof (a verifiable engineering report from a private repo, no code shown), surviving-lines (share of surviving lines next to commit share) and ai-slop-linter (the tells of machine writing, with line numbers). MIT, tests, CI on three operating systems, four outside pull requests merged in the first day.
Cendra
One of two founding engineers: primary owner of the web application's 27 product areas and both native mobile apps, of the product layer around Cendra's AI, and of the frontend path to production. The distinguishing deep dive: eliminating roughly 19,000 unnecessary pushes a day, extrapolated from production telemetry.
ReadyFly
Made the first commit and authored roughly 75% of the web app (157 of 209 commits) behind Maya, ReadyFly's AI career agent — you don't apply; Maya brings interview invites. Built Maya's candidate experience, the live dual-agent landing readyfly.io serves today, and the site's GDPR consent enforcement.
Interfarm
Named in a TÜBİTAK-funded proposal as the only person listed for its AI and machine-learning work, and built both halves of that brief: the fuzzy-logic control layer deciding climate, nutrient and lighting behaviour inside a sealed vertical farm, and the browser application it is operated through.
Actio
Milapasa's digital event-management product — registration, participant categorisation and reporting. I designed its landing page, represented the product in the field and moderated its live events, running QR-code check-in with the team.
Archive Engineering
An autonomous documentary pipeline built on verified US public-domain sources, where originality and rights are enforced as architecture: SHA-256 provenance hashing and a default-deny rights ledger gate every clip before it can be used.

Twelve Checks That Could Not Fail
A reader pointed out that three characters in my release script were what made a broken check pass. He was right, and I measured it. Then I counted how many other checks in my own repositories had the same shape: twelve, in one week, all mine.
The Smoke Test That Could Not Fail
A release pipeline ended with a step that installed the published package on three operating systems and confirmed the version. It reported success against a version the registry was not serving, because the check looked for the version string anywhere in the output and the failure message quotes it back. Five more checks in the same repositories had the same shape.
I made my coding agent explain every change to the customer. Here is the skill.
The product-engineer skill: every commit carries a plain-language section for the person paying for the work, and why that turned out to change what got built, not only how it was described.

I’m open to senior, founding and product-engineering roles in the UK where I can work close to the problem, the users and the code.
