Iyola Oyabiyi O.

Led frontend delivery for a Vue 3 + TypeScript SPA with multi-tenant workflows, role-based access control, and API-driven UI state aligned to backend contracts.

• Architected a scalable SPA foundation (routing, state management, API client abstraction, error handling) to improve delivery consistency and reduce integration friction.
• Aligned UI state and permissions with backend contracts across organization/project scopes, reducing edge-case regressions through clearer contracts and stricter typing.
• Improved UX predictability for complex workflows by standardizing loading/error states and defensive UI patterns for partial/failing network conditions (Chrome DevTools network profiling).

Built high-performance landing pages and authentication flows for Web3 products, prioritizing speed, accessibility, and measurable funnel improvements.

• Achieved LCP < 2s and CLS < 0.1 through performance-first UI and asset optimization (Lighthouse, PSI, WebPageTest).
• Improved onboarding completion time ~35% by reducing friction in critical steps and validating funnel behavior (GA4).
• Improved conversion tracking accuracy ~25% via GTM/GA4 event instrumentation, validation, and QA checks (GTM, GA4).

Built a high-performance, mobile-first website for a US personal care home, optimized for accessibility, conversion, and operational reliability.

• Delivered Lighthouse/PSI scores of 99/100/100/100 (lab) via a zero-dependency vanilla stack and performance-first rendering strategy (Lighthouse, PSI).
• Validated real-world load behavior and bottlenecks using network/waterfall profiling (Chrome DevTools, WebPageTest).
• Audited accessibility with axe/WAVE and monitored availability with UptimeRobot for dependable service discovery (axe, WAVE, UptimeRobot).

Built a WordPress + Elementor + ACF platform and improved admin workflows for self-service content and bookings.

• Reduced support dependency by ~80% by enabling client self-management and clearer admin UX (client feedback + workflow validation).
• Reduced data load ~45% and improved admin responsiveness ~35% via query and caching improvements (Chrome DevTools, WebPageTest).
• Sustained performance scores in the 90s and improved technical SEO readiness (Lighthouse, PSI, Search Console).

Built a responsive marketing website and improved performance, indexing, and engagement through technical SEO and analytics-driven iteration.

• Hit sub-2s load targets through modular layout and asset optimization (Lighthouse, PSI, Chrome DevTools).
• Improved indexing speed ~60% and CTR visibility ~25% through technical SEO fixes and sitemap hygiene (Search Console).
• Increased engagement ~20% by refining page structure and event tracking for key actions (GA4, GTM).

Shipped frontend features in sprint cycles across React/Next.js projects with a focus on reusable components and production-minded delivery.

• Built and shipped React/Next.js UI features under tight deadlines, focusing on predictable state and resilient API-driven interfaces.
• Collaborated with backend engineers on API contracts; implemented loading/error states and edge-case handling for smoother UX.
• Improved delivery consistency by standardizing component patterns and lightweight documentation for teammates.
