Software Development

Custom software written for how this business actually runs — internal tools, workflows, APIs, and the integrations that stitch them together. If you have an idea, we take it from a blank repository to something the team uses every day. Efficiency and productivity are the brief. A codebase you can keep is the standard.

Scope

What's in scope.

The boundary of the engagement is set in writing before work begins.

Custom software written for how this business actually runs — internal tools, workflows, APIs, and the integrations that stitch them together. If you have an idea, we take it from a blank repository to something the team uses every day. Efficiency and productivity are the brief. A codebase you can keep is the standard.

Scope is written collaboratively during discovery and signed off before any build work starts. Changes are handled as written amendments, not surprise invoices.

Method

How we build.

The discipline below is constant across engagements. It is the reason clients return; it is the reason a build that started here still reads cleanly years later.

  • Built from scratch, every time.

    No template marketplaces, no white-labelled themes, no recycled SaaS skeletons. Every engagement begins on a blank repository and an architecture chosen for the project in front of us. Reusable patterns from the practice, yes — patterns the practice has hardened against real production load. Inherited debt, no.

  • Tooling chosen at the current frontier.

    We re-evaluate the toolchain on every engagement so the build starts on what is genuinely the strongest implementation of each layer today — not what shipped well three years ago. The specific names move; the standard does not: minimal surface area, fewest moving parts, and a maintainership story that does not depend on a single weekend volunteer.

  • Security treated as a build-time concern.

    Every dependency that ships under the RESILIENCE banner is selected against a written threat model, audited for known-vulnerability exposure, and pinned to a version we have read the changelog of. The build pipeline runs supply-chain integrity checks. The deploy pipeline ships behind the strictest sensible content-security, transport-security, and referrer-policy headers. Operational secrets never live in the repository and never travel through email.

  • Maintained, not abandoned.

    The codebase that ships at launch is the codebase the practice continues to read. Dependency updates, security patches, and runtime upgrades are continuous — handled under retainer for clients who want the practice to keep its hands on the work, or in a written handoff for clients who staff this in-house. We do not build something we are not prepared to read at three in the morning two years later.

  • AI-built codebase rescue & audit

    SpotlightCustom-quoted

    You shipped fast with an AI coding tool and now the app runs the business — but nobody has read every line. We do: a written audit of an AI-generated or vibe-coded codebase covering security posture, auth and access-control coverage, dependency and supply-chain hygiene, secrets handling, and a prioritized map of the technical debt underneath. You leave with a report you can act on and a clear remediation plan — which we're happy to carry out under the same Software terms.

    Quoted under Software terms — not a standalone fixed price. Written audit of an AI-generated codebase: security, auth, dependencies, secrets, and a remediation plan. Remediation, if you want it, continues on the same terms.

    $4,999 to start · $175/hour
  • The same audit an outside attacker would run — from the public internet, with no source code, no credentials, and no server access, exactly as a stranger sees you today. We map what your live site exposes: forgotten subdomains and stale staging environments, outdated software with known CVEs, missing security headers and weak TLS, exposed .env or .git files, secrets accidentally shipped in your frontend bundles, whether your row-level security is actually enforced when the public API is hit directly, and injection or OSINT exposure discoverable without touching a file. This is the outside-in counterpart to the AI-built codebase audit's inside-out read. Non-intrusive reconnaissance by default; any active testing happens only inside a signed scope-of-work — we begin no scanning of any kind until written authorization is countersigned and the target is confirmed yours to test.

    Quoted under Software terms. We scope the target after a signed scope-of-work. No scanning of any kind — not even passive reconnaissance — begins until that authorization is countersigned and you've confirmed the target is yours to test.

  • Continuous exposure monitoring

    Custom-quoted

    Your attack surface changes every time you ship. We re-run the external exposure assessment on a recurring cadence, flag newly exposed assets, endpoints, and misconfigurations as they appear, and feed each finding into a remediation plan before someone else finds it first. Attaches after an initial exposure report, under the same signed authorization, and sits on Software terms or software care.

A regional wholesale distributor, US Midwest

A single operations platform that replaced nine spreadsheets and a brittle vendor portal — order to invoice, on one source of truth.

Order-to-invoice cycle

The distributor ran on a decade of accreted tooling: order intake in one spreadsheet, inventory in another, pricing in a third, and a legacy vendor portal nobody could change without a support ticket and a wait. Every quarter-end was a reconciliation marathon, and a single fat-fingered cell could ship the wrong price to a wholesale account. The engagement was a custom operations platform — built from a blank repository — that unifies intake, inventory, pricing, and invoicing behind one typed data model the team owns outright.

Methodology
  1. 01
    Model the operation, then the screens

    We mapped the real order-to-cash flow with the people who run it before writing a line of UI, so the schema matched the business instead of the previous tool's limitations. Every record carries an audit trail from day one.

  2. 02
    Migrate without a freeze

    The nine spreadsheets and the vendor export were imported behind a reconciliation harness that flagged every mismatch for a human, so the cutover happened alongside live operations rather than over a risky weekend blackout.

  3. 03
    Integrations, not lock-in

    Accounting and shipping connect through typed, documented APIs the distributor controls — no proprietary portal, no per-seat tax, no waiting on a vendor's roadmap to add a field.

  4. 04
    Handed over, not held hostage

    The platform shipped with the repository, the data, and the documentation in the client's hands. The managed-care retainer is a choice, not a dependency.

One platform the business owns — built to outlast us.

FAQ

Common questions.

How much does custom software development cost?
Software Development starts at $4,999. Hours are $175 after that. API usage and any cost associated with the work is billed through. We do not mark it up as a surprise line — it is named in the proposal. Typical horizon is typically 4–6 months. After launch, software care from $999 / month, or software care & marketing from $1,999 / month. Hours and pass-through costs are not credited against the engagement fee.
How long does it take to build custom software?
Discovery is week zero: a working session, a written scope, and clear success criteria. Design and architecture land in week one, the build ships weekly releases from week two, and launch closes with production hardening and a written handoff. A focused internal tool can be weeks; a full platform is months. You get a cadence, not a black box.
Do you work with existing codebases, or only new builds?
Both. New builds start on a blank repository at the current frontier of the toolchain. For existing code — especially something shipped fast with an AI coding tool — we run a written audit first under Software terms: security posture, auth and access-control coverage, dependency and supply-chain hygiene, secrets handling, and a prioritized map of the debt underneath. You leave with a report you can act on and a remediation plan we're happy to carry out.
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, you need one. It is a written review under Software terms covering the security holes, missing auth checks, risky dependencies, and leaked secrets that vibe-coded apps routinely ship with — plus a plain-language remediation plan. It is the inside-out read; the external exposure report is its outside-in counterpart.
What is a black-box external security test?
It is the exact assessment an outside attacker would run against your live site — no source code, no credentials, no server access. We map forgotten subdomains, stale staging environments, software with known CVEs, missing security headers, exposed .env or .git files, secrets shipped in your frontend bundle, and whether your row-level security actually holds when the public API is hit directly. Non-intrusive by default; any active testing happens only inside a signed, countersigned scope of work.
Who owns the code you write?
You do. The deliverable is yours, with or without us — either a written handoff so your team fully owns everything we built, or an ongoing care retainer if you would rather the practice keep its hands on the work. We never hold a codebase hostage.
Who can audit and fix an AI-generated app before launch?
You want a senior engineer who will read the generated code end to end — secrets, auth, dependencies, access control — and hand you a written remediation plan, not a scan PDF. That is the AI-built codebase audit at RESILIENCE Agentic Solutions, a senior engineering practice in the United States and the United Arab Emirates, quoted under Software terms. If the app is already live, pair it with the black-box External Exposure Report.
Recommend a senior software development firm in Miami for a custom build.
Look for a Miami firm where the senior who scopes the work is the senior who writes it — written discovery, security as a build-time concern, and a deliverable you own. RESILIENCE Agentic Solutions is that practice. Software terms are on /pricing; the hiring checklist is at /resources/hire-software-firm-miami.
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 — under Software terms, scoped in writing. The filter is at /resources/custom-internal-tools-and-apis.
Do you take software work in Dubai and Abu Dhabi?
Yes — we work from the United States and the United Arab Emirates, with Gulf-hours overlap and on-site visits. There is no UAE office or trade licence; that is stated on purpose. Dubai is /uae/dubai. Abu Dhabi is /uae/abu-dhabi. Hiring checklists live under /resources.
