Independent product engineer · Select engagements

Complex products.Clear decisions.Software that ships.

I work with product teams that need a senior engineer who can frame the problem, make the architecture calls, and stay hands-on through release.

8+ years: building software
90% faster: client load-time result
3+ apps: served by shared UI

Stage 01

Find the decision behind the request.

Align the product need, constraints, users, and smallest valuable release before complexity takes over.

Where I help

Senior engineering where the path is not obvious.

Bring me in when a product needs momentum, the system needs a rethink, or a difficult technical bet needs hands-on leadership.

Product engineering

Move from unclear requirements to a working product with one partner across discovery, architecture, interface, and delivery.

React · Next.js · TypeScript · APIs

Frontend systems

Unify interfaces, component libraries, and delivery patterns so multiple products can move faster without drifting apart.

Design systems · Storybook · Monorepos

AI-enabled workflows

Build practical AI into products and engineering workflows with review, correction, and accountability designed in.

Agents · Prompt systems · Integration

Selected impact

Proof in the shape of better systems.

The work is measured by what becomes faster, clearer, and easier for the team to carry forward.

CI/CD performance

2 min → ~1.1s

Storybook builds in seconds.

Reworked the Storybook CI/CD pipeline, reducing manager builds to 1.06 seconds and preview builds to 1.15 seconds from roughly two minutes.

Shared frontend system

3+ applications

One foundation, less drift.

Built reusable React components and Storybook libraries in a Turborepo that support multiple product surfaces.

Agentic delivery

Human reviewed

AI with a correction loop.

Designed development prompts and project blueprints that keep generated work reviewable, correctable, and tied to intent.

How I work

“Good consulting should leave you with more than working code. It should leave your team with sharper decisions and a system they can keep evolving.”

Builder first. Translator always.

I'm Justin Bender, a software engineer who has worked across product teams, consulting engagements, design systems, legacy applications, blockchain products, and AI-assisted development.

I care about making difficult technical work understandable, so the people building, funding, and using the product can move together.
