Engineering Philosophy & Culture

How I Work & Lead

Senior engineering isn't just about writing code—it's about how we de-risk architecture, elevate teammates through mentorship, and partner with product to build software that lasts.

De-risking delivery before writing the first line of code.

Proactive Architectural Planning

Complex initiatives stall when assumptions remain unstated. I author thorough development plans defining API contracts, data models, edge-case behavior (such as multi-timezone handling and boundary conditions), and rollback strategies. This creates cross-team clarity and eliminates costly downstream refactors.

API ContractsSchema DesignEdge-Case MappingRollback Strategy
Code review as an engineering accelerator, not a bottleneck.

High-Accountability Code Reviews

I treat code reviews as one of the highest-leverage opportunities for team mentorship and code health. I provide constructive, actionable feedback with clear architectural rationale and concrete examples, while encouraging small, reviewable PRs that maintain team velocity.

Actionable FeedbackDesign RationalesPair ProgrammingKnowledge Dissemination
Treating UI performance and accessibility as core engineering requirements.

Product-Minded Frontend Craftsmanship

Great frontend engineering balances deep systems thinking with fine-grained interaction design. I obsess over sub-200ms interactions, resilient data handling during network flakiness, keyboard navigability, and semantic accessibility (WCAG AA), ensuring complex workflows feel natural and responsive.

Quality by Construction & Safeguards

Production stability is never sustained by manual QA cycles. I establish comprehensive automated testing suites using Playwright for critical user journeys and React Testing Library for component resilience, combined with defensive data modeling to prevent invalid application states.

Background & Craft

Engineering software that stands the test of production.

I'm a senior software engineer with over 9 years of professional experience building web products that handle complex, high-stakes domain logic. Over my career—spanning enterprise financial modeling at HiBob, high-concurrency payroll and attendance engines at When I Work, and real-time workforce monitoring at Calabrio—I've focused on turning intricate backend workflows into fluid, dependable user interfaces.

Beyond frontend architecture, I have a deep appreciation for the entire product lifecycle. As the founder and developer of Somm Scribe, I took a consumer SaaS application from initial sketch to live production—handling everything from Go REST API services and database architecture to Stripe subscription billing, Cloud Run deployments, and AI-driven taste recommendations.

I lead through clarity: authoring detailed architectural development plans, championing constructive code review practices, pairing with teammates to solve thorny state bugs, and partnering closely with product managers and designers to resolve ambiguity before code gets written.

ColophonHow this site was built

This portfolio is engineered with the same discipline I bring to production applications. Built on Next.js 15 and React 19 using custom CSS Modules and strict design tokens—with zero heavy third-party component libraries. The result is a sub-110kB initial client footprint, instantaneous page transitions, semantic HTML, and strict accessibility adherence.
