Custom software development

By · Updated

Short answer

PunkSolid designs and builds custom software—integrations, background jobs, admin utilities, and supporting services— with AI-assisted implementation in Cursor and human review on architecture and security. Clients receive full access to the finished code and optional 1:1 Cursor coaching for their own developers.

Custom software development is for problems that do not fit a SaaS checkbox: syncing catalogs, transforming content for static builds, bridging CRMs, or replacing brittle scripts that grew around WordPress imports. PunkSolid implements in Cursor with explicit interfaces and human review before anything touches production data.

What we build

Typical deliverables include import pipelines, webhooks, small admin services, deployment helpers, and glue code between marketing sites and operations tools. When the primary surface is a customer-facing browser app, start with web app development and add custom services as supporting repos in the same engagement.

Plugin development applies when the extension must live inside WordPress, Shopify, or another platform runtime rather than as a standalone service.

Delivery discipline

Our methodology treats agents as accelerators, not approvers. Specs and tests precede wide refactors. We use spec-driven development on larger efforts so reviewers can see acceptance criteria in git—not buried in chat transcripts.

For repos that already contain agent-generated code, add AI code review before you connect production credentials.

Experience from large migrations

Eight healthcare provider rebuilds—each 1,000–6,000 pages—required in-code replacements for ACF-style fields and bulk import tooling that used to live in WordPress plugins. The healthcare WordPress rebuilds case study describes how structured content and tracking parity were carried across those launches. Custom software work often underpins similar migrations even when the public site is static HTML.

Across client and network work we count nine sites rebuilt with full repository handoff. We do not publish client revenue or lead figures.

Ownership and coaching

You receive repositories, environment samples, and runbooks—full code ownership at handoff. Optional 1:1 Cursor coaching helps your team extend imports, adjust mappings, or debug failed jobs without waiting on us.

We do not state prices or guaranteed timelines here; both follow discovery.

Marketing-heavy work may still belong under website development. Platform-specific extensions belong under plugin development.

When requirements are clear enough to discuss interfaces, contact us with systems diagrams or sample payloads.

Observability and failure modes

Custom software fails in boring ways: silent queue stalls, duplicate webhooks, or imports that partially succeed. We document expected retries, idempotency keys, and manual recovery steps in the runbook—not only in chat. Logs should answer who changed what and which batch ID broke, especially when replacing WP All Import-style jobs with code-first pipelines like those used on large healthcare migrations.

Team fit

This service suits technical owners who can grant API credentials, approve maintenance windows, and assign an internal stakeholder for acceptance tests. If nobody on your side can run staging smoke tests, we scope that explicitly rather than assume unlimited access to production.

Independence

PunkSolid is not affiliated with Cursor or Anthropic. Tooling names appear only to describe implementation. Client counts, revenue figures, and unnamed healthcare brands stay off this page per our case study disclosures.

Examples shaped like real migrations

Import jobs that mirror WP All Export schedules, nightly syncs that rewrite only changed records, and admin tools that let compliance officers approve form copy without FTP are typical scopes. Each gets acceptance tests on sample files before production cron enables. When software underpins a public site launch, coordinate timelines with website migration so cutover and job schedules do not fight each other.

Support boundaries after handoff

We document on-call expectations during transition weeks if you scope them. Otherwise handoff assumes your team owns pager rotation. We do not imply unlimited lifetime maintenance in the base engagement.

Batch importers should log row counts and failure reasons to a place support teams can search. We wire those logs into your existing observability stack when one exists, rather than inventing a proprietary dashboard you cannot export.

When software only exists to support a replatform, we time its retirement in the roadmap so you are not paying to maintain temporary glue years after the public site has moved.

Language choice follows your ops team: TypeScript, Python, or PHP extensions each have different hosting constraints. Discovery records that decision so agents do not rewrite working modules into a stack your runtime cannot ship.

Share sample payloads and SLAs on contact when you are ready to define interfaces. Include failure alerts your ops team already monitors so new jobs do not spam the wrong channel.

How it works

  1. Scope and interfaces

    We document inputs, outputs, SLAs, and failure modes for each integration or job before writing production code.

  2. Build in small releases

    Work lands in reviewable chunks with type checks and tests on critical paths. Agents handle repetitive code; senior review covers data integrity and permissions.

  3. Operate safely

    Logging, alerts, and rollback steps are defined for production. We validate against staging credentials you provide.

  4. Transfer ownership

    Handoff includes repositories, runbooks, and optional coaching so your team can extend or host the software.

What you get

Engagement

Model
Project or retainer-style phases scoped after discovery
Typical timeline
Depends on integration count and compliance review; we publish a milestone plan before implementation

FAQ

Is this different from web app development?

Web app development focuses on browser-facing products with accounts and UI. Custom software often ships APIs, workers, CLIs, or services that other systems call—sometimes alongside a small admin UI.

Can you modernize an existing codebase?

Yes. We frequently pair new features with [legacy application modernization](/services/legacy-modernization/) so revenue-critical systems keep running during refactors.

Do you lock us into your hosting?

No. You receive the full source and deploy where your policy requires. We document the pipeline we used during delivery.

How do we start?
