Business platforms, mobile apps and connected systems for companies that have outgrown spreadsheets, paper and group chats. You work directly with the engineer who builds it.
When the business has outgrown shared files, paper forms and group chats, we build the system that replaces them: scheduling, work orders, inventory, invoicing, and the admin panel to run it all. APIs, database and server included.
Field crews, drivers, customers and staff who are never at a computer. Cross-platform iOS and Android apps built in Flutter, from first screen to store submission and the releases after it.
Turning a product idea into something that signs people up and bills them: accounts and roles, subscriptions, notifications, analytics, and a dashboard the owner can actually read.
Eight shipped products — some our own, some built for clients. Open any one to see the problem it solves and what is behind it.
Digital loyalty cards for local businesses — QR check-ins, push campaigns and a dashboard that shows who came back.

Most people have never commissioned software before. This is the shape of it, so you know what you are agreeing to.
How the work actually gets done today, where it breaks, and what a fix would be worth. Usually a conversation and a walk through your current process.
Scope, screens, data model and the order things get built in. You see what you are getting before anyone writes code.
Development in visible increments, with the real integrations wired up and tested against your real cases, not a demo dataset.
Deployment, store submission where it applies, and an arrangement for maintenance that we agree on in writing.
123Yotta is a one-engineer studio in Ocala, Florida, run by Freddy Arenas — a computer engineer with more than 20 years building business applications, backend platforms, automation and custom integrations. The company was formed in 2023; the experience behind it is considerably older.
That means no account manager relaying your requirements to someone you never meet. The person who sits down to understand your operation is the person who designs the database, writes the code, provisions the server and submits the app.
It also means being honest about size. This is not a large agency and does not pretend to be one. For projects where deep involvement and direct access matter more than headcount, that is the advantage.
A few lines about what you are trying to solve is enough to start. You will hear back from Freddy, not from a sales team.
