Lead Software Engineer

Matthew Clark

I build understandable systems for complex product behavior.

I lead frontend architecture for complex customer-facing React and TypeScript products, carrying product decisions across APIs, testing, accessibility, security, and production delivery.

Black-and-white portrait of Matthew Clark
Working principle

Make the product decision clear, keep system boundaries explicit, and leave evidence that the result works.

01 / Professional impact

Evidence from production systems

Across my State Farm tenure, I've architected and delivered customer-facing life-insurance workflows that connect frontend behavior, APIs, testing, security, and production delivery.

Additional work includes runtime-image optimization, vulnerability remediation, deployment visibility, and mentoring engineers.

02 / Projects

Independent systems

Selected product work where the problem, architecture, tradeoffs, and verification are available for inspection.

Featured project / 01

Pay Period Planner

An independently built household cash-flow product that turns income, bills, savings, and debt into a clear next-paycheck plan. Its accessible React workflows connect to an authenticated Spring Boot API, versioned PostgreSQL data, and cross-layer verification.

03 / Approach

How I lead the work

Clarify the product

Start with the decision a person needs to make, then turn ambiguous requirements into explicit behavior and testable outcomes.

Design the boundaries

Keep state, domain rules, API contracts, and data ownership clear across the stack.

Build confidence

Combine tests, accessibility, security, documentation, reviews, and mentoring so the team can deliver reliably.
