What this covers

Software built around a specific internal process, rather than off-the-shelf software forced to fit.

Real examples of what's been built

ERPs, HR portals, and booking/scheduling systems, drawn from actual project history.

Tech stack

React/Next.js, Node.js/NestJS, PostgreSQL.

Process

Requirements gathering around actual workflow, build, internal testing with real users, then handoff and training.

Why custom vs. off-the-shelf

Custom costs more upfront. It pays off when the business process is specific enough that generic software creates workarounds instead of solving the problem.

FAQ

Common questions

How is this different from just buying existing HR/ERP software?

Off-the-shelf software fits a generic process. Custom software fits your actual workflow — no workarounds required.

Do you handle data migration from spreadsheets or legacy systems?

Yes, migrating data from spreadsheets or legacy systems is part of typical project scope.

Who maintains the system after it's built?

Ongoing maintenance is available after launch, handled directly rather than handed off blind.

What if our internal process changes after the system is built — can it be updated?

Yes — custom systems are built to be extended as the underlying process changes.

Do you build the whole system, or specific modules within an existing internal tool?

Both — full systems or specific modules bolted onto an existing internal tool.
