Custom software & product development

Got something serious to build?
This is the part we love.

Beyond websites, Rune builds real software: custom apps, APIs, dashboards, automations, and whole products, from the first idea to launch. This is the work Erik did for years as a founding engineer at venture-backed companies, now available to yours.

What we build

From a single automation to a whole product

Whether you know exactly what you need or just have a problem to solve, we can take it from idea to shipped.

Product development

Full 0-to-1 product builds, the kind of work Erik has done as a founding engineer. From a raw idea to a real, shipped product people use.

Discovery & scoping

Not sure exactly what to build yet? We map the what and the how first, so you spend your budget on the right thing instead of guessing.

Custom software & internal tools

Software tailored to exactly how you work, the things off-the-shelf tools just cannot do.

APIs & integrations

Connect your systems and make your tools talk to each other, with data flowing where it needs to go.

Dashboards & admin tools

See your whole operation at a glance and run it without a mess of spreadsheets and duct tape.

Automation & AI

Kill the repetitive work. Automations and AI that handle the busywork so your team does not have to.

For growing companies

Software for growing companies

For companies from twenty people to a few hundred, in Sacramento and anywhere in the country. The senior engineer you talk to is the one who writes the code: no offshore bench, no account managers.

Systems integration

CRM, ERP, accounting, and field tools connected so data moves between them on its own.

Internal tools

Scheduling, quoting, and compliance tracking in software your whole team can use, with permissions and an audit trail.

Customer portals

A secure place where clients see their projects, documents, and invoices.

Legacy modernization

Aging systems rebuilt incrementally while the business keeps running on them.

How engagements work

01

Discovery

A short, fixed-price phase to understand the problem, review your systems, and produce a written plan.

  • Stakeholder interviews and system review
  • Architecture and written scope
  • Fixed quote for the build, yours to keep
02

Fixed-scope build

A defined system delivered in visible milestones, from internal tool to customer-facing platform.

  • A working demo and written status every week
  • Code in your repository from day one
  • Documentation and handoff built in
03

Ongoing engineering

A senior engineer on a monthly retainer to keep improving a system, or working alongside your in-house team.

  • Works in your repositories and process
  • Support after launch
  • Same engineer who built it
The engineer behind it

Built by someone who has shipped real products

On a custom project you work directly with Erik, start to finish. No account managers, no handoffs.

Erik Mellum has spent over a decade building software, including as a founding engineer at venture-backed companies. He holds a Computer Science degree from Chico State and teaches Web Development and the Capstone course at Butte College. The same person who scoped and shipped software for tech companies is the one who builds yours.
