A buyer asking for a senior software development firm in Miami is usually trying to avoid a familiar outcome: a polished pitch, a junior bench, a timeline that slips, and a codebase nobody wants to own. Miami has plenty of shops. The useful filter is not a ranking. It is a short set of questions that tell you who will actually write the code.
This is the checklist we would want used on us.
Who writes the code after you sign
Ask, in the first conversation: who will write my software, and will that be the same person I am talking to now. One senior engineer on every line, every commit, and every email is a different product from a salesperson handing the work to whoever is free. If the answer is a rotating bench, you are buying utilization, not judgment.
Miami vs. remote is secondary. Time zone and the ability to sit in a room matter. What matters more is continuity — the person who scoped the work is the person who ships it.
Scope and price in writing before a contract
A serious firm insists on a discovery call before a number: a working session, a written plan, success criteria you can point at. Instant quotes with no questions are padded or about to grow. Open-ended time with no named hourly is how well-intentioned projects double.
Software Development retainer is $6,500 upfront, then $165/hour. API usage and project costs are billed through and named in the proposal. Most builds run 4–6 months, on average. The written scope names the date. The $1,500 Build Blueprint credits 100% to the engagement retainer if you sign within 14 days (two weeks). After that the blueprint is still yours and the full retainer is due. Hours, pass-through costs, and the monthlies are not reduced. Those terms are on /pricing.
Security as a build-time concern, not an upsell
Ask how they think about security and listen for whether it is a phase at the end or a discipline from the first commit. Dependencies vetted, secrets kept out of the repo, sensible defaults, auth designed in — not a scan bolted on the week before launch.
If the software will handle logins, payments, or personal data, a partner who cannot give a clear, unpanicked answer is telling you something important.
What you own when the build ends
You should own the code, the accounts, and the documentation, with a clean handoff if your team takes over — or an honest, optional care arrangement if you would rather they keep maintaining it. A codebase held hostage is not a partnership.
Ask up front: at the end, do I fully own and control everything, and can I leave. A confident yes is a good sign.
