Razonity LLC · Software development studio
We design, build and operate mobile apps, web applications and websites, with AI integrated where it genuinely makes a difference. Senior engineers, serverless infrastructure, and one team from first call to launch and beyond.

What we build
Most projects need more than one of these. Because one team builds all four, the app, the back end and the site are designed together and stay that way.
iOS and Android from one codebase. React Native apps that feel native, ship through both stores, and share their logic with your web product.
SaaS platforms, customer portals, internal tools and dashboards. React front ends on serverless AWS back ends that scale from zero to whatever comes.
Marketing sites and landing pages that load instantly, rank well and convert. Pre-rendered and served from a CDN, with no server to patch.
Assistants, agents and automation built on frontier models, grounded in your own data, and shipped with the guardrails production needs.
How it works
Working software every week, decisions written down, and a launch that runs as a checklist. Nothing about the project should be a surprise, including the end of it.
01
A short, structured conversation about what you need, who it is for and what success looks like. You leave with a written scope, not a sales pitch.
02
Flows, screens and the data model before any code. Clickable prototypes where they help, so the expensive decisions get made while they are still cheap.
03
Working software on real infrastructure, demonstrated every week. No big reveal at the end, and no surprises in it.
04
Store submissions, DNS, monitoring, documentation, handover. Launch is a checklist we run, not a day we hope goes well.
05
Measure what people actually do, then build what the data says is next. We stay on as the team that knows the codebase.
Why Razonity
Small, senior and direct. The way we work is the product as much as the code is.
The people you talk to are the people who design, build and ship it. There is no handoff to a bench you never meet.
Built on AWS Lambda, DynamoDB and CloudFront: nothing to patch, costs that scale with use, and infrastructure that shrugs off a traffic spike.
We ship AI features when they change the outcome for your users, and we will tell you plainly when they would not.
Your code, your cloud account, your data. Handed over documented and deployable, with no dependency on us to keep it running.
Least-privilege access, encryption at rest and in transit, and tenant isolation designed into the data model from the first table.
A written scope, a weekly demo and a single person who answers. You always know where the project stands and what happens next.
Typical engagements
Every project is different, but most requests arrive as one of these. If yours does not, that is usually the interesting kind.
Self-service accounts, scheduling and payments in a responsive web app, with a mobile companion that shares the same API.
The workflow your team actually runs on, rebuilt as a proper application with roles, audit history and the integrations the spreadsheet never had.
A copilot that answers from your documents and systems, with citations, permissions and monitoring, inside the product your customers already use.
Tell us what you are building. We will come back with questions, a rough approach and a clear next step.
