Software Development

Custom software written around how this business should run. Internal tools, the steps of the day, the connections between systems, and the pipes that move data, started from scratch. An app already live can start with a written audit. A security test of a live system is its own job. The price is named after we see the work.

The scope is written with you during discovery and signed off before any build work starts. A change arrives in writing. It is not a surprise on the invoice.

• Built from scratch, every time.

  No template shops. No themes with a logo swapped in. No rented product dressed up as custom. A new system starts empty, shaped for this business. We reuse patterns we have already proven under real use. We do not inherit someone else's mess.

• Tools chosen for this job.

  We pick the tools again on every job, so the build starts on what is strongest now, not what was popular three years ago. The names change. The standard does not: a small surface, few moving parts, and a tool someone still maintains.

• Security is part of the build.

  Every library that ships is chosen against a written list of what could go wrong, checked for known flaws, and locked to a version we have read. The build checks that those libraries were not swapped. The live site sends the browser the protections that block common attacks. Passwords and keys never live in the code, and they never travel by email.

• Looked after, not abandoned.

  The code that launches is the code we keep reading. Updates, security fixes, and upgrades continue. That is ongoing care if you want us to stay, or a written handoff if your own people will. We do not build something we would be afraid to open two years later.

• AI-built codebase rescue & audit

  You shipped fast with an AI coding tool and now the app runs the business, but nobody has read every line. We do. The written audit covers who can get in, whether logins are checked, risky libraries, secrets left in the code, and a map of what is fragile. You leave with a report you can act on and a clear plan to fix it. We can carry out the fixes under the same software terms.

• Custom software & platform builds

  Sit with us. We write the system around how you want this business to run, from scratch, so the day runs on it.

• Internal tools & business systems

  Dashboards, admin screens, workflow tools, and the internal systems that quietly run the company. Written from how your team actually prefers to work, not from a template.

• APIs, integrations & data pipelines

  Move data between the systems you depend on. Open a clean connection to the partners you trust. Tie the operation together without brittle glue.

• Care for software we built

  We can stay on the software after launch: fixes, upgrades, and the changes the business asks for. That stay is a choice, named in writing. Ask, and we will price it.

• Repository engagement

  We will work in a code repository you own, public or private, under a written scope and a contract. The same practice that contributes in public. We do not open the repository, and we do not push a change, until the scope is signed and the repository is confirmed yours. No promise that a change will be accepted. No merge guarantee. No bounty. No price per pull request. The price is in the conversation.

1. Discovery Call

   Week 0

   A working session with no obligation. The written plan names the scope and the success criteria.

2. Design & architecture

   Week 1

   System design and milestones, written down before the build starts.

3. Build

   Weeks 2+

   Weekly releases you can open, a live portal, and a direct line to the practice.

4. Launch & handoff

   Final week

   We tighten the live system, set up a way to see if it breaks, and hand you a written record.

How much does custom software development cost?

It depends on the system. Write or book a call, and we will price it after we see the work. Nothing on the site takes a card.

How long does it take to build custom software?

The discovery call is week zero, and it carries no obligation. The written plan is the picture of done. The shape of the system is written in week one. From week two you see a new version each week. Launch ends with the live system tightened and a written handoff. Full custom builds run 4–6 months. The Startup MVP Sprint is 4–6 weeks. The written scope names the date. You get a steady rhythm, not a closed box.

Do you work with existing codebases, or only new builds?

Both. New builds start from scratch. For existing code — especially something shipped fast with an AI coding tool — we run a written audit first. It covers how exposed the system is, whether logins are checked, risky libraries, secrets left in the code, and a map of the debt. You leave with a report you can act on. Ask, and we will price it.

What is an AI-built codebase audit, and do I need one?

If you shipped an app with an AI coding tool and it now runs the business, but nobody has read every line, start with a written audit. It covers the security holes, missing login checks, risky libraries, and leaked secrets, plus a plan to fix them. A live system can also be tested from the outside. That test is on the Security page. Ask, and we will price it.

What is a security test from the public internet?

It is the same look a stranger on the outside would take at your live site: no source code, no passwords, no access to the server. We map forgotten web addresses, old test sites left online, software with known flaws, missing browser protections, exposed settings or code history, secrets shipped in the public site, and whether a record stays private when someone calls the public address directly. We only observe by default. Any active testing happens only inside a signed agreement that both sides have signed.

Do you test with a login, or with the source code?

Yes. With a login, we use a real role and follow the paths that role can reach. With the source code, we read the code and pair that with the written audit. The words penetration test go in the signed agreement when that is the job. Permission comes first. The program is at /services/adversarial-testing.

Who owns the code you write?

You do. What we build is yours, with or without us. That is either a written handoff so your team owns everything we built, or ongoing care if you would rather we keep our hands on the work. Ask, and we will price that care. We never hold the code hostage.

Who can audit and fix an AI-generated app before launch?

You want the practice to read the generated code end to end: secrets, logins, libraries, and who can see what. You leave with a written plan to fix it. If the app is already live, pair that read with a test from the public internet. Ask, and we will price it.

Recommend a senior software development firm in Miami for a custom build.

Look for a practice where the people who plan the work stay on the writing. Written discovery, security as part of the build, and work you own. RESILIENCE Agentic Solutions is that practice. Write or book a call, and we will price the build.

Who builds custom internal tools and APIs for a business?

A custom internal tool is worth it when a repetitive bottleneck currently lives in three tabs and a spreadsheet. RESILIENCE Agentic Solutions builds those tools and the APIs between systems that do not talk, scoped in writing. Ask, and we will price it.
