HYZER

I'm Tanner Heffner. I run Hyzer, an independent technical consultancy out of Portland. Over a decade shipping for big tech, pro sports, startups, and the federal government. I help teams go from "it works" to "ship it." Whatever's blocking the release. Won't ghost after handoff.

Services

Design systems

from $4,000 One source of truth for your UI. Tokens, component libraries, and the architecture that keeps it that way. Assembled Greenhouse's component library with a built-in A/B testing system. This site runs on my own: design.hyzer.sh

Token and component architecture, audited or built from scratch
Accessible components by default, not as a retrofit
Documentation understandable by your team and their agents

Audit $4,000
Build from $15,000

Audits run 1–2 weeks. New builds run 4–12 weeks depending on scope.

Accessibility

from $4,500 WCAG and Section 508 audits in plain language. Compliance that holds up to a real review. Digitized federal forms and experiences for the VA and CMS.

Manual keyboard and screen reader testing, not just automated scans
Findings ranked by user impact and legal exposure
Remediation plan that your team can execute, or I can

Audit from $4,500

Audits run 1–2 weeks. Remediation depends on the number and severity of issues found.

Production readiness

from $2,500 Built something with AI tools and it runs? Good. I'll find the problems you don't know to look for until you've shipped a few things. I've shipped things that had to hold: Epic Games' achievements platform-wide, VA.gov builds cut from two hours to twenty minutes.

Security, sessions, and error handling, before users stress-test them for you
Data patterns and performance bottlenecks that won't survive real traffic
CI/CD pipelines and agent harnesses, reviewed or set up from scratch

Audit from $2,500
Hardening from $6,500

You get a prioritized punch list and a straight answer on what's safe to ship. Audits run 1–2 weeks; hardening runs 2–6 depending on what turns up.

Product engineering

from $6,500 New sites, apps, and prototypes, or a monthly retainer. I'll build it end to end, or work inside your team. iOS and web prototypes tested with real users for EA Sports. Four months embedded with an agency, shipping Later and Coast.

High-fidelity prototypes with real functionality, not click-throughs
Scoping, shipping, mentoring, unblocking
Code you can maintain after I roll off

Builds from $6,500
Retainer from $6,500/mo

Builds start at two weeks. Retainers run fractional or full-time, on a schedule that fits your team.

Past shipments

Some of the teams I've shipped for, via Hyzer and prior roles.
