PROFILE

Senior Frontend Engineer with 5+ years of commercial experience across multiple independent web, mobile and shared-
platform repositories. Builds complex React and TypeScript products, identifies repeated product and engineering
constraints, and turns them into maintainable frontend foundations. Brings hands-on ownership from architecture and
implementation through release and production support.

EXPERIENCE

Searates | Senior Frontend Developer | 2021 - July 2026
Junior → Frontend Developer → Senior Frontend Developer
PLATFORM & ARCHITECTURE
Identified repeated map implementations and recurring bugs across teams, then initiated and drove a shared Module
Federation map platform adopted across all frontend teams and multiple applications per team; became the cross-team
point of contact for integration and architecture.
Reworked a complex messaging state/filtering layer after identifying duplicated logic, difficult pagination/state
maintenance and broad unnecessary rerenders; introduced composable selector-based rules that localized updates and
made filtering behavior easier to extend.
Built component-lifecycle-aware storage for dynamic request forms so fields removed from UI were excluded from final
payload; kept UI state frontend-friendly and transformed to backend contracts at submission.
PRODUCT, UI & PERFORMANCE
Worked across multiple independent applications and repositories within the SeaRates product ecosystem, spanning
customer-facing web products, CRM-style tools, mobile, SEO-focused sites and shared frontend platforms. Operated
with a high degree of autonomy, regularly identifying technical and product problems, initiating work and driving
solutions through implementation and release.
Implemented custom viewport-based list virtualization for large selectors/lists (up to ~1000 items), rendering only visible
items plus a buffer while preserving correct scroll dimensions through calculated total content height.
Investigated unnecessary React rerenders and reduced overly broad component dependencies; used memoization for
expensive derived computations; applied state/dependency architecture (not generic optimization rules) to localize
updates. Used lazy imports for rarely visited routes/pages and configured Webpack chunking/code splitting; worked with
Module Federation for shared module delivery.
Designed reusable UI component APIs and variants in Storybook for common controls including buttons, selectors,
modals and tables, supporting a gradual move away from duplicated product-specific implementations.
Worked with Next.js SSR and Server Components in production, including middleware-based auth, caching, dynamic
routing and SEO-focused rendering.

MOBILE PLATFORM & DELIVERY
Served as one of the primary React Native engineers (~3 years) on a production mobile application; stronger ownership
on the iOS delivery path. Production mobile application served approximately 150k-250k monthly users.
Introduced a configuration-driven internal screen/navigation layer (DefineStack / DefineScreen / DefineSheet concepts)
that registered screens/stacks/sheets through compact configuration objects, separated platform/service concerns from
feature logic, and centralized common layout and platform behavior. The refactor reduced the mobile codebase by
roughly 30% (approximate engineering measurement).
Worked with deep links, permissions, native APIs, push notifications, analytics, Sentry, Expo, EAS, Fastlane, Xcode and
App Store Connect. Defined backend requirements for mobile features such as push notifications.
Built an internal Tauri-based release utility that automated mobile delivery workflow, including versioning, changelog
generation, build preparation and App Store delivery. Integrated Sentry into the React Native production app and used
error reports and stack traces to investigate production crashes.
LEADERSHIP & OWNERSHIP
Mentored a junior engineer for approximately six months through code review, task decomposition and implementation
guidance, helping them progress toward independently handling mid-level responsibilities.
Acted as a cross-team technical point of contact for the shared map platform, contributing to architecture and integration
decisions as the approach became the standard direction for map-based features.
