Hello, I'm Arda. I build automations, create applications, and code iOS apps.

AI Front Desk · SaaS

OwlAgenda

OwlAgenda is my own product: an AI front desk for service businesses. It replies to every message that comes in on Instagram and WhatsApp in under a minute, day or night, in the customer's own language. It answers questions such as prices and opening hours from the business's own knowledge base, asks what the person needs and hands the conversation to the team when a human is needed.

Messages arrive through Meta's WhatsApp and Instagram webhooks and n8n workflows; replies are written with the Claude API in a TypeScript service built on Hono and Zod. Each business gets a web panel on Cloudflare Workers and D1 that shows first-reply times, after-hours replies, conversations and handoffs. Win-back campaigns reach old enquiries and past customers only when people have given marketing consent, in line with KVKK, İYS and GDPR.

The idea is simple: no message waits until morning, and no customer is lost because nobody answered.

Native macOS · Menu Bar Utility

NotchFi

NotchFi is my Mac app that puts the internet connection where you already look: the top of the screen. A slim island beside the notch shows signal and live download speed. Hover over it and it opens into a full card with signal in dBm, channel, upload and download speeds on a 60-second graph, and the last speed test.

It is built for iPhone Hotspot too: it spots tethering, shows the carrier's name, tracks mobile data against your plan and warns at 80% and 100%. A one-click speed test on Cloudflare's network measures download, upload, latency and jitter, with a lighter test on metered connections. Short alerts drop into the notch when the connection drops, comes back or switches network, and the menu bar shows every detail, from Wi-Fi standard and band to noise and router address.

No account, no analytics, no tracking: everything stays on the Mac. It is free on the Mac App Store, runs on macOS 14 Sonoma and later, and speaks 45 languages.

Football Fan Project · 3D Web

Jersey Collection of Arda

As a football fan, I wanted to list the jerseys I own in a way a photo album never could. Jersey Collection is a white 3D showroom where every shirt hangs on a real rail: hover one and it turns to face you, drag to spin it, pull it off its hanger and flick it into the basket, where it crumples and becomes a shipping parcel. Hold the rail and the hangers slide like beads, and a click on any shirt opens a clean product sheet with front and back photos, sizes and a description.

It is a single static page built with three.js and WebGL. Each product photo is cut out with a Python image pipeline (Pillow and NumPy), then inflated into a soft 3D shell with front and back textures. Hanging, swaying, sliding and the basket run on custom spring and rigid-body physics, with GLSL shaders for the crumpling. A live bag and checkout (sizes, quantities, promo codes, shipping options and an animated card preview) updates in real time and ships the parcels away once you pay. It is a demo checkout: no payment is taken.

It also doubles as a sales demo of how a clothing brand could present its collection in a more tangible, playful way.

Prompt Library · Motion Graphics

Claude Video Styles

A gallery of eleven animated explainer styles, from paper cut-outs and risograph prints to isometric drawings, liquid glass, ASCII art and particles. Each style has a looping preview video. Pick one, type a topic, choose landscape or portrait, turn on a storyboard, voice-over or sound effects, and the page writes a long, ready-to-run prompt.

Paste that prompt into Claude Code and it builds the animation and renders an MP4. A companion skill turns any reference image, such as a poster you like, into a new reusable style. It is a single static page in plain HTML, CSS and JavaScript, and it remembers your settings in the browser.
