About

On the job, I primarily work on frontend with React, TypeScript, JavaScript, HTML & CSS. Over the years, I have worked on many React projects across product features, design systems, data-heavy UIs, accessibility, testing, and production fixes. I have mostly dealt with things like CSS-in-JS, React Testing Library, React Query, GraphQL, Apollo, Zustand, Cypress, Vitest, and TypeScript. On the side, I keep myself updated with Next.js, Tailwind CSS, and AI-assisted development tools. Primary technologies I'm hands-on with: 💻 React 💻 JavaScript, TypeScript, HTML & CSS 💻 Testing: React Testing Library, Cypress, Vitest 💻 State/Data: React Query, Apollo, Zustand, GraphQL Secondary technologies I've worked with: 💻 React Native (mostly side projects / learning) 💻 WordPress 💻 SQL/PostgreSQL 💻 Ionic 💻 Java (Core, Spring Boot & Multi-threading) 💻 Python Besides this, I used to build apps outside work - back in college and my early career years - just to learn and to make something useful: https://play.google.com/store/apps/dev?id=8312708476046119513 Background: I am one of those people who works hard and gives their 100%, but due to a lack of natural talent, ends up getting around average from life. A lack of resources, opportunities, and potential peers has hindered my progress of geekdom, but has also enabled me to keep realistic, one-lifetime-doable goals. I try hard to exceed my potential and readily accept new experiences that bring in new knowledge. I have always liked being more versatile than specialized. Objective: To be unique and to make ripples in many areas of my field, but ultimately generate waves as I find “my niche” that suits my persona.

Work experience

Product Engineer at Turn.io, Mar 2026 - Present · 6 mos, Denver, CO, • Architected the AI Logs/Tracing frontend - React + Phoenix LiveView console for LLM observability: real-time session tailing UI, multi-dimensional filter popovers, deep-linkable inspection drawers, and infinite scroll. • Led the Unified Apps Catalog frontend from settings sub-page to main navigation - catalog cards, About pages, version-history UI, and URL-persisted filters wired to LiveView assigns. • Accelerated the React Flow journey canvas for 100+ node graphs via virtualized off-screen nodes, drag-to-reorder interactions, and a workspace error boundary - ending multi-second freezes and white-screen crashes. • Polished an in-canvas AI journey-writing assistant to shippable form - refined streaming SSE response UX, left-docked panel layout, and added lightweight per-node card-reference quick actions. • Built reusable design-system components (PopoverMenuSearch, CascadingMenu) in HEEx/React, adopted across AI Logs, Inbox, and AI Assistant settings with Storybook documentation. • Hardened frontend reliability - stabilised flaky Cypress suites, sharded Vitest CI, and resolved 15+ stale Apollo cache and React state bugs across canvas, inbox, and templates.
