Elijah Kotyluk
Senior staff engineer.
Architecture, reliability, performance.
Former Vuetify core team member, now owning platform architecture, reliability, security, and web performance for a national ecommerce brand. I take on the work where failure costs revenue: zero-downtime migrations, provider failover, and search visibility.
- Vuetify core team
- 2019 to 2023, now listed among the project legends.
- 78 merged pull requests
- to vuetifyjs/vuetify, and 130 across the organization.
- Three replatforms led end to end
- The latest in six months, with a zero-downtime cutover.
What I take on
- Replatforms and migrations
- Three led end to end, including Remix on Shopify Oxygen and Hydrogen with a zero-downtime cutover. Planned so the business never notices the switch.
- Reliability and failover
- Systems that keep revenue flowing when Shopify, Cloudflare, or GitHub go down. Designed before the outage, not during it.
- Performance and search visibility
- Core Web Vitals, hydration deferral, media guidelines, competitive PageSpeed reporting, and AEO and SEO strategy. Measured before and after.
- Vue and Vuetify
- Upgrades, component libraries, and the hard bugs, from someone who spent four years inside the Vuetify codebase.
- AI tooling and adoption
- Bringing Claude and Claude Code into an engineering org: tooling, guardrails, and the workflows that make it stick.
- Mentoring
- I mentor and tutor people working through computer science degrees and coding bootcamps: fundamentals, debugging habits, code review, and the jump from coursework to shipping real software.
Selected work
Vuetify
Material component framework for Vue. Contributor from 2019 and core team through 2023, across the framework, plugins, docs, and tooling.
Vue / TypeScript
Ecommerce storefront
Remix on Shopify Oxygen and Hydrogen, migrated with a zero-downtime cutover including the Cloudflare Workers in front of it. Failover, performance, and search visibility owned end to end. Name withheld.
Remix / Hydrogen / Cloudflare Workers / TypeScript
unrift
A lightweight TypeScript test framework, ESM first with a CJS fallback and esbuild transforms, so there is no separate compile step. Published on npm with its own docs site.
TypeScript / Node
devoid
Dead code analysis for JavaScript and TypeScript: unused exports, identifiers, and files, unreachable re-exports, and usage traced through barrels and wildcards. Built on the TypeScript compiler API with no other dependencies.
TypeScript / Node
Working together
Remote, based in the US. Short engagements and ongoing fractional work both fit. The fastest way to start is an email with what you are building and where it hurts.
