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.
Talent Visa Journey
A members-only community and private preparation workspace for people on the UK Global Talent, O-1, EB-1A, EB-2 NIW and H-1B routes: those preparing, visa holders who help, and lawyers and advisers. Live at talentvisajourney.com in English and Turkish, with sign-up open since 15 October 2026.
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; 33 pull requests from seven outside contributors merged. Alongside them, four fixes of mine merged upstream in three organisations: langchain-ai/openwiki, mastra-ai/mastra and redis/ioredis.
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 independently designed and developed its promotional landing page while formally an IT Analyst, then represented the product in the field and ran 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.
Latest writing
Humanizer has about 60,000 stars. On 12 public tasks my linter plugin scored 2.67 higher
ai-slop-linter against six other tools and no tool on 12 public rewriting tasks, graded blind, and the held-out set where the top tools tied.
(opens in a new tab)surviving-lines scored highest in a six-arm code-ownership benchmark
surviving-lines against five other ways of answering who wrote the code still in a repository, on public tasks and on a sealed set written by someone who never saw the tool, with the limits of each result.
(opens in a new tab)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.
Building an early-stage product that needs end-to-end ownership?
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.
