$ whoami → Founder @ CTSS LLC
Founder of CTSS LLC — a US product studio shipping vertical SaaS across education, legal, healthcare and local services, serving 5,000+ learners. QA engineer at heart, educator by nature.
Partnered with industry leaders
01 — About
I'm a builder with 5+ years across QA, front-end and Agile product leadership. I run CTSS LLC, a bootstrapped product studio: an exam-prep academy that more than doubles the national pass rate, a no-code academy platform, a dental ecosystem, special-education software and more. Underneath it all I'm a QA engineer — so everything I ship is quality-first.

I've tested products at Yum! Brands, built a 10-person delivery team through 150+ interviews, hosted a 200+ episode podcast and designed a 6-month bootcamp that turns beginners into job-ready testers. Agile at heart, teacher by nature, founder by choice.

How I work
01
We align on goals, scope and requirements together before a line of code is written.
02
Flows, interface and prototype bring the product to life and confirm direction early.
03
Agile sprints with a QA-first discipline guarantee quality from the very first commit.
04
We ship, measure and continuously improve — staying with you as you grow.
04 — Experience
Bootstrapped product studio shipping vertical SaaS: CoursePod.io (10+ institutions, 50+ instructors, 5,000+ students), Dent-IS (1,000+ members, 500K+ transactions), hibep and Boş Koltuk — both in acquisition discussions.
Built a subscription exam-prep academy for legal-profession candidates — 500+ students, ~1% market share in three months and a 75% pass rate versus the ~35% national average. The build that became CoursePod.io.
Designed and teach a 6-month software-testing engineering course — Selenium, JUnit, Postman — with 20+ graduates, half through one-on-one training.
Owned vision and backlog, ran the Scrum cycle and designed the pixel-based purchase model behind 200,000+ parcel sales. Built a 10-person team through 150+ interviews.
Grew a bilingual (EN/TR) tech podcast to 200+ episodes and #1 in its category in New Zealand — and used it as a marketing engine for my products.
Set strategy, built teams and delivered client work end to end: a turnkey front-end for GizmoTourizm, an R&D digitalization project with the Ankara Bar Association and the 4kWeeks archive.
Ran a 3-month project from scope to on-time, on-budget delivery with a cross-functional team, tracked in Jira and Trello.
Functional and non-functional test plans for web and mobile; Selenium, Cypress and Postman; BDD with Cucumber/Gherkin; CI in Jenkins and GitLab.
Coordinated daily operations, inventory and order tracking while keeping customer satisfaction consistently high.
Built responsive admin and order panels with React and Tailwind, real-time sync over REST and WebSockets, tested with Jest, Mocha and Cypress.
Managed receivables and collections and supported the office through an active public-tender bid.
Taught elementary and middle-school students through hands-on, experiential learning.
R&D on the 'Arvento Kids' tracking device (C#, real-time GPS) and the 'Arvento Race' boat-racing analytics program.

He is a person I mentored at the beginning of his adventure and enjoyed it immensely. He loves his job and you can tell it from his eyes.
Besides being a stand-alone team, he is a very good team player. He's a total playmaker. I very much enjoy working with him.
In addition to being successful in his field, he is a multidisciplinary character. This reflects in his work.
