Software built for how your business actually works.

I'm Luke Henry. I build custom software for businesses that have outgrown spreadsheets, copy-and-paste, and tools that don't talk to each other.

You work with me directly, from the first call to launch and after. No account managers, no junior handoffs, and none of the overhead of a big agency.

Tell me about your project See how I can help

From first idea to production, and after.

Projects are sized to fit you, from a one-week review of what you have to building a whole new system.

Custom applicationsWhen off-the-shelf software makes your team work around it.

Web apps, mobile apps, and internal tools built around the way your team already works.

  • Web apps and customer portals
  • Internal dashboards that replace the spreadsheet everyone fights with
  • Updating old systems so they're faster and safer to change

Connecting your systemsWhen your team re-types the same data into three places.

I get your tools talking to each other and automate the repetitive manual work in between.

  • Connecting the software you already pay for, through its APIs
  • Shopify, Twilio, TikTok, and CRM integrations
  • Automating routine steps so orders and records flow on their own

Technical adviceWhen you need a senior engineer's judgment, not a full-time hire.

A second opinion before you spend money, or ongoing guidance while your project grows.

  • Reviews of your existing software and its code
  • Part-time technical leadership for teams without a CTO
  • Build-or-buy decisions and plans for keeping software up to date

A clear process with no surprises.

You always know what's being built, why, and what it costs.

Discover

I start by understanding your business, your customers, and the problem worth solving, before writing any code.

Plan

You get a written proposal with milestones, a timeline, and a fixed or capped budget.

Build

Work ships in short rounds with regular demos, so you see progress and can steer early.

Support

After launch, I handle documentation, handoff, and ongoing maintenance, whatever keeps things running smoothly.

One senior engineer. No handoffs.

Authentech is my practice. I'm a principal full-stack engineer with 12+ years of experience building software platforms in healthcare, HR, marketing, and e-commerce. I've led engineering teams, rebuilt major applications, and worked alongside company leadership on technical plans.

When you hire Authentech, the person you talk to is the person building your software. Nothing gets lost between a salesperson, a project manager, and a developer. I focus on practical, maintainable work: software your team can understand, extend, and own long after the project ends.

Have a project in mind?

Tell me what's slowing your team down. You don't need a spec or the right technical words; a plain description is plenty.

  1. I read it myself. Your message comes straight to me, not to a sales team.
  2. We talk it through. A first consultation is always free, to see whether I'm the right fit.
  3. You get a written proposal with a timeline and a fixed or capped budget.
