The same process we used to build OjitoResume RoastRoast Interview

01Our work

Our apps are our proof.

Before building yours, we built our own, with real AI inside. Here is what each one shows and where it is today.

OjitoOur productIn testing

Label scanner for families

Computer vision and nutrition rules

The problem
Reading a label at the supermarket takes time, and what works for an adult does not always work for a baby.
What we built
An app that reads the barcode and answers Good, Fair or Avoid for each person at home, with the reason, based on Colombian warning labels, additives and allergies.
The AI inside
  • Barcode reading with the camera
  • AI that reads the nutrition table and ingredients from a photo
  • Nutrition rules by age and allergy
Platforms

iOS and Android · Spanish and English

Coming soon to Google Play and the App Store

See Ojito
Screen from Ojito: Ojito says Good, 94 out of 100, for a moisturizing cream.
Screen from Ojito: Ojito says Good, 70 out of 100, for oat cookies, and for your baby, not yet: they contain added sugar.

Resume RoastOur productAvailable

AI resume review

Document AI and scoring

The problem
Job seekers rarely know why their resume does not get past the filters, or what to change.
What we built
An app that reads a resume as text, PDF, Word or a photo, scores it out of 100, matches it to a job posting and rewrites it without inventing anything, with a PDF that applicant tracking systems can read.
The AI inside
  • Document AI: reads PDF, Word and photos
  • AI scoring and red flags
  • Guided rewrite for a job posting

Roast InterviewOur productComing soon

AI interview practice

A voice AI interviewer

The problem
Rehearsing with generic questions does not prepare you for the ones you will really be asked.
What we built
An AI interviewer that asks about your resume, adapts the pressure to your answers, listens to your voice and gives you a score and a verdict for the role.
The AI inside
  • Voice AI interviewer
  • Speech to text, without keeping the audio
  • A score and verdict calibrated to the role

Screen from Roast Interview: The interviewer asks: “Your CV says you cut p95 latency by 40%. Measured where, against what baseline, and how do you know it wasn’t the new hardware?”

02What we build

Apps that solve something, with AI where it helps.

03How we work

AI agents do the heavy lifting. A person reviews every decision.

  1. Discovery

    We get to know your idea, your users and the problem. We come out with a clear scope, what goes into the first version, and dates.

    People

  2. Design

    Screens and flows you can tap through on your phone before any code is written. AI explores options; you and we decide.

    AI + human review

  3. AI-built, human-reviewed

    AI agents write and test the code in parallel, and a person on the team reviews and approves every change before it goes in.

    AI + human review

  4. Quality

    Automated tests, accessibility review and testing on real phones, on iPhone and Android.

    AI + human review

  5. Launch on the App Store and Google Play

    Store listings, screenshots, privacy policy and terms, and getting through Apple’s and Google’s review.

    People

  6. Operation

    After launch: metrics, bugs, store updates and new features.

    AI + human review

05Questions

Frequently asked questions

WhatsApp +57 350 495 8312
Privacy policy

Is my idea protected?

Yes. Your idea is yours: we treat it as confidential, we do not share it or use it for anything other than replying to you, and if you want, we sign a non-disclosure agreement (NDA) before the first call.

How long does it take?

It depends on the scope. A focused MVP is measured in weeks, not months. On the first call we give you an estimate, and the proposal includes dates and what goes into each delivery.

Who owns the code?

You do. The code, the designs and the store accounts are in your company’s name, and the contract says so in writing.

Do you publish the app in the stores?

Yes. We prepare the listings, screenshots, privacy policy and terms, and take the app through Apple’s and Google’s review, as we do with our own apps. The app ships under your company’s developer account.

How do you handle data privacy?

We design for Colombia’s personal data protection law (Ley 1581 of 2012) from the start: we ask only for the data needed, say what it is used for and help you prepare the privacy policy. If your app is for other countries, we take their rules and the stores’ rules into account.

Which languages do you work in?

English and Spanish, and your app can ship in both, like all of ours. We work with companies in Colombia, Latin America and the United States.

Do you work with US companies?

Yes. Medellín is on UTC−5: the same time as the US East Coast in winter, and one hour behind in summer. Meetings fit in your workday.

What does AI do, and what do people do?

AI agents write code, tests and drafts in parallel, which is why we move fast. Product and design decisions, and every change that goes into the code, are reviewed and approved by a person on the team.
