Custom software development, from the developer you talk to
Off-the-shelf tools stop fitting when your process is the thing that makes you different. I build custom software around that process: the data model, the screens your team uses every day, the integrations with the tools you already pay for, and the automations that remove the busywork.
Custom software development services for the way you actually work
Most custom software is not a moonshot. It is an internal tool that replaces three spreadsheets, a portal where clients see their status, or a dashboard that pulls data from systems that never talked to each other. I scope it around one question: what does your team do every day that software should be doing for them?
- Internal tools and admin dashboards
- Client and customer portals with accounts and roles
- Integrations with Stripe, POS, CRMs and public data
- Workflow automation and AI steps where they earn their place
- SaaS products, from first version to paying customers
A custom software developer instead of an agency
With an agency you brief a project manager who briefs a team. With me you talk to the person who writes the code, so decisions take a message instead of a meeting, and nothing gets lost between design, frontend and backend.
That is how I built ServeStack's engine of around 30 modules and 65 Prisma models, the merchant dashboard and the manager app around it, and ClerkSide, which turns NYC open data into a violation search with a case workflow.
Custom software development for startups and small businesses
For startups, the goal is the smallest version that real users will pay for, on a stack a team can grow. For small businesses, it is software that pays for itself in hours saved or orders won. Both get a written scope, weekly releases on a live preview URL and a codebase you own from day one.
If you are comparing quotes, my guide to small business website cost explains what moves a price up or down, and the same logic applies to custom software: the number of user roles, integrations and screens drives most of the cost.

Questions
What is custom software development?
Designing and building software for one business's specific process instead of adapting a generic product: internal tools, portals, integrations, automations or a full SaaS product.
How much does custom software development cost?
It depends on the number of user roles, screens and integrations. I give a fixed scope and price after a short call, so you know the number before any code is written.
Do you work with startups or established businesses?
Both. Founders usually need an MVP that can grow; established businesses usually need a tool that replaces manual work. The process is the same: scope, weekly releases, launch.
Who owns the code?
You do. The repository, the hosting accounts and the data belong to you from the first day.
Can you add AI to the software?
Yes, where it saves real time: AI agents that take actions, search over your own data, or document and email processing. See AI agent development for that side of my work.
