Bespoke Application Development

Custom-built desktop, web, and internal tools written specifically around your workflow — not adapted from a template. We scope the exact logic your business runs on, write clean, documented, version-controlled code, and hand over something your own team can maintain long after we've shipped it. Stack: TypeScript, Python, Node.js, Go, depending on the problem.

Legacy Code Modernization & Refactoring

Inherited a codebase nobody understands? We audit it, document it, and refactor it into something stable — without a risky full rewrite unless one is genuinely justified. Dependency upgrades, test coverage, performance profiling, and incremental migration plans that keep the business running while we work.

Custom Integrations & Scripting

The connective tissue between the tools you already use: custom scripts, data pipelines, and one-off integrations that off-the-shelf automation platforms can't handle. Cron jobs, ETL scripts, file processing, and system-to-system syncs written in Python or Node.js, deployed and monitored properly — not left running on someone's laptop.

Code Review, Audits & Technical Due Diligence

Before you acquire, invest in, or inherit a codebase, we review it. Architecture quality, security posture, technical debt, and scalability risk — delivered as a clear written report your leadership team can actually use to make a decision.

Custom Development Process

Scope — We map the exact problem, constraints, and edge cases before a line of code is written. Architecture — Technical spec, data model, and integration points agreed in writing. Build — Weekly sprints, staging environments, and PR reviews you can follow. Test — Unit and integration test coverage on every non-trivial engagement. Handover — Documentation and a walkthrough so your team owns the code, not just the output.

Frequently asked questions

What counts as "custom coding" versus your other development services?

If your project fits cleanly into a website, API, or SaaS product build, those dedicated services usually get you there faster. This service is for everything else — bespoke tools, scripts, integrations, refactors, and audits that don't fit a standard package.

Can you work with our existing codebase?

Yes. Most custom coding engagements start with us reading and understanding code we didn't write, not a blank repository.

How is custom coding priced?

Scoped projects are quoted after a short technical discovery call. Ongoing coding support runs on the same sprint-based retainer model as our other development services, starting from $1,499/month.

Do you sign NDAs before reviewing our code?

Yes, as standard for any code review, audit, or due diligence engagement.
