Web app development

Web app development at PunkSolid covers products that need accounts, roles, and server-side logic—not only public marketing pages. We implement in Cursor with the same review gates we use on large content migrations: specs, human checks, and automated tests on the paths that carry revenue or sensitive data.

Typical projects

Common scopes include customer self-service portals, booking or intake flows with CRM handoff, authenticated reporting dashboards, and internal tools that replace spreadsheets. If the work is primarily editorial HTML with hundreds of landing URLs, website development is usually the better entry point.

When the codebase already exists but runs on an aging framework, combine this engagement with legacy application modernization so you can ship features while replatforming in smaller steps.

Engineering practices

We describe our delivery habits on methodology: agents propose diffs; people approve architecture and releases. For non-trivial features we align with spec-driven development so acceptance criteria live in the repo.

Security review covers authentication flows, session handling, dependency updates, and obvious secret leaks—especially when the first draft came from an agent. AI code review can be added as a focused pass before your team owns ongoing releases.

Proof from production work

We have rebuilt nine sites across client and network work, including eight large healthcare provider websites documented in healthcare WordPress rebuilds. Those projects required HIPAA-aware forms, call tracking, and analytics parity—not only faster HTML. Web apps inherit the same discipline: integrations are planned before cutover, not discovered in production outages.

We quote PageSpeed scores only when we have lab measurements. Core Web Vitals in Search Console are tracked separately after launch.

Integrations and handoff

During discovery we list CRMs, payment providers, identity systems, and webhooks that must stay stable. You receive deploy documentation and optional 1:1 Cursor coaching so your developers can extend the app after handoff.

We do not list prices or guaranteed delivery dates on this page; both depend on scope discovered on the call.

Next steps

Compare custom software development when the deliverable is primarily APIs, workers, or plugins rather than a browser-facing app. Read claude code development if you specifically want delivery centered on Claude Code alongside Cursor.

Compliance and data handling

When apps process health, financial, or other regulated data, discovery must list retention rules, audit expectations, and which subprocessors may receive exports. We configure environments so production credentials never land in agent chat logs. If you already run HIPAA-aware forms or CRM lead endpoints on sibling marketing sites, we align patterns documented in healthcare WordPress rebuilds—custom endpoints, consent, and call tracking where those tools are in scope.

Operations after launch

Handoff includes how to run migrations, rotate keys, and roll back a bad deploy. We describe which alerts to watch on error rates or queue depth when background jobs exist. Optional coaching covers branching, code review in Cursor, and running the test suite before merge so your team inherits habits—not only files.

What this service does not include

We do not guarantee feature parity with every SaaS unicorn chart, unlimited post-launch support without a scoped agreement, or invented uptime percentages. Performance claims on public pages reference lab PageSpeed scores separately from Core Web Vitals field data in Search Console.

Architectures we see often

Server components or islands with an API boundary, background workers for webhooks, and edge-hosted static marketing pages feeding authenticated apps are common patterns. We pick storage and auth only after discovery—this page does not endorse a single database or identity vendor. When apps expose public marketing pages, SEO checks from website development apply to those routes inside the same program.

Long-term ownership

Because you retain repositories—code ownership by default—we document how agents should and should not touch production config. Cursor rules guide and agents.md guide patterns often appear in handoff repos so the next contractor inherits guardrails.

When your roadmap includes mobile clients later, we document API contracts in the same repo so agents do not fork duplicate business logic into a separate prototype.

Feature flags belong in the handoff doc when partial launches are planned. We wire flags so marketing can enable modules without emergency deploys on Friday evenings.
