You talk to the people doing the work
There’s no chain of managers in between. You ask your question to the person who writes the code.

We build software that makes everyday work easier.
Hill is a small software team. We’ve built a Turkish-speaking voice assistant for businesses, a virtual number service for SMS verification, and a tool that adjusts your CV to every job post. We build products for other companies, too.

Our own products.
Each one came out of a problem we, or people around us, ran into every day. Two are live, one is in early access.
All productsA voice assistant that answers your customers in Turkish.
What time do you open, how much is it, where are you… The same questions come in every day. YzÇağrıMerkezi answers them with the information you enter, books the appointment once the customer says yes, and leaves a transcript of the call in your dashboard.
- Try it by talking in your browser. No phone number needed.
- It never books an appointment without a clear yes.
- Free for 7 days, no card required.

- Customer
Hi, are you open on Saturday?
- Assistant
Hi. We’re open 10 am to 2 pm on Saturday. A standard service takes about 30 minutes.
- Customer
Do you have anything at 11?
- Assistant
Saturday at 11 is free. Shall I book a standard service for you at that time?
- Customer
Yes, please.

Sample conversation. The assistant uses the information the business enters in its dashboard.
Get SMS verification without giving out your own number.
An app wants a phone number to sign you up, but you’d rather not hand over your own. On SMSDogrulama you pick the service and the country, get a number right away, and the code usually lands in your dashboard within a minute or two.
- Numbers from more than 150 countries.
- If the code doesn’t arrive in 20 minutes, the order is cancelled and refunded.
- Available in Turkish, English and five more languages.
A different CV for every job.
Sending the same CV everywhere is easy, but it rarely works. CVFY reads the job post, brings forward the parts of your experience that fit, and rewrites your bullet points more clearly. It never adds things you didn’t do.
- Compares your CV with the keywords in the job post.
- Writes in Turkish and English.
- You approve every change.

We build for other companies, too.
Whatever we learn building our own products goes into client work. If you have a product in mind, or a project that stalled halfway, let’s talk.

03 · How we work
Fewer meetings, more work done.
We show something working first
Instead of weeks of documents, we get a clickable first version out quickly. It makes every conversation easier.
Speed is planned from day one
How fast pages load, whether everyone can use them, and tests are part of the plan from the start.
The code is yours
Source code, docs and servers live in your accounts. You can continue with another team any day you like.
04 · Tools
We pick what’s solid, not what’s trendy.
For a product that needs looking after for years, we use what we know best rather than the newest library. And we use AI where it actually helps.

Things we’ve learned.
- When should a voice assistant count a “yes” as yes?The hardest part of building YzÇağrıMerkezi wasn’t speech recognition. It was consent. Here’s how we decide when an appointment actually gets booked.
- Performance budgets that actually holdA performance budget isn’t a document you write and forget. It’s a simple rule that stops the build when you cross the line and shows up in every PR.
- Building a bilingual product from day oneLeaving translation until the end is the most expensive mistake a bilingual product can make. Practical ways to plan for Turkish and English from day one.
