Engineering lead at sahibinden.com. Maker of small, private apps.

I have been building for the web for eighteen years, the last eleven at [sahibinden.com,] one of Türkiye's largest marketplaces. By day I lead the team behind identity, fraud prevention and messaging. By night I ship my own apps, end to end.

Side projects

What I build after hours.

Outside my day job I design, build and ship small apps on my own, end to end. Three of them are below. They share one rule: private by design.

Kapsül·Slapss·Pano

iOS · Android

Kapsül. Your health, without the noise.

An AI nutrition and medication tracker. Calm by design, supportive instead of judgmental. No ads, no tracking.

Today

Your day, at a glance.

Doses, calories and the next thing to do, on one calm screen.

Meals

Snap your plate, calories fill in.

Take a photo and calories and macros are filled in within seconds.

Goals

Your goal, made clear.

Daily targets and progress without the guilt trip.

Medicine

Scan the box, schedule ready.

Point the camera at a medicine box and get a starting schedule with a reminder for every dose.

Family

Look after the ones you love.

Caregiver roles let you follow a parent's or child's routine from your own phone.

OriginKapsül started as my son's research project, which placed in the TÜBİTAK Asia finals. We kept building it together until it shipped.

Slapss. Meetings you can't miss.

A quiet banner never stood a chance against deep focus. Keep scrolling to see what Slapss does instead.

It takes the whole screen.

On every display, the second your meeting starts. One tap to join Zoom, Teams, Meet or Webex.

Pano. The clipboard with a memory.

A searchable clipboard history for people who copy code all day. It ships without the network entitlement, so nothing can leave your Mac.

Search

Everything you ever copied, found instantly.

Unlimited history on SQLite FTS5 with a tiny query language: type:code, app:xcode, >7d.

Transforms

Type json. Paste it pretty.

JSON, Base64, JWT, slug, URL and Markdown conversions run right in the search field.

Colours

Copy a hex, paste a Tailwind class.

rgb(), hsl(), SwiftUI and the nearest Tailwind class, side by side.

OCR

Screenshots become searchable text.

Apple Vision reads the text out of copied images, on device. Secrets like API keys and card numbers expire after an hour.
