Case Studies

Deep-dives into key enterprise projects I have designed, architected, and built throughout my career.

Silverlight to Angular Migration

Lead Front-End Architect · Enterprise Energy Client

AngularRxJSTypeScriptMicro Frontends

The Challenge

A massive, business-critical oil & gas management console built on deprecated Silverlight was nearing end-of-life. It comprised 120+ complex screens with real-time data visualizers and had to be migrated without interrupting active operations.

The Solution

Designed a hybrid architecture that embedded Angular micro frontends alongside the legacy application using a message-bus bridge. This allowed for an incremental, screen-by-screen migration and continuous deployments. Built custom canvas-based charting libraries to replace heavy legacy visualization controls.

The Impact

Successfully completed migration ahead of schedule with zero operational downtime. Reduced application initial load time by 45% and improved CPU/Memory efficiency by 60%.

Metadata-Driven UI Rendering Engine

Senior UI Engineer · Large Financial Services Platform

ReactTypeScriptJSON SchemaDynamic UI

The Challenge

Product forms and user onboarding flows were tightly coupled with backend APIs. Any new field request or workflow change required code modifications, full build cycles, and synchronized frontend-backend releases.

The Solution

Engineered a schema-driven UI renderer using React and TypeScript. The system parsed dynamically-fetched JSON schemas mapping field definitions, layout configurations, and client-side validation rules. Developed a drag-and-drop schema builder tool for product managers.

The Impact

Reduced the time-to-market for launching new country onboarding flows from 3 weeks to less than 2 hours. Eliminated 85% of standard frontend request tickets.

WCAG 2.1 AA Accessibility Overhaul

Accessibility Lead & Engineer · EdTech Platform (500K+ Active Users)

Semantic HTMLWAI-ARIAScreen ReadersA11y Auditing

The Challenge

The platform faced compliance reviews due to deficient accessibility support. Keyboard navigation was broken, interactive focus states were non-existent, and screen readers failed to parse dynamic search results.

The Solution

Led a comprehensive audit utilizing automated tooling (Axe, Lighthouse) and manual NVDA/VoiceOver screen reader testing. Rewrote critical interactive modules (modals, dropdowns, auto-suggest inputs) to adhere to WAI-ARIA standards. Established a company-wide a11y component library and linting rules.

The Impact

Elevated the platform's accessibility compliance score from 78% to 94%, securing multi-million dollar school district contracts. Conducted workshops to train 25+ developers on inclusive design practices.
