Leads frontend architecture and AI-first modernisation for two enterprise fleet-management dashboards, turning five years of product and domain knowledge into a repeatable engineering system for safe migration and faster delivery.

• Pioneered an AI-first modernisation pilot and expanded it across the team after proving the workflow, compressing an effort expected to take years into a production launch in roughly six months.
• Converted five years of product, architecture, business-rule, and edge-case knowledge into modular AGENTS.md and engineering documents that evolve alongside the code.
• Built model-agnostic context routing that gives each task only the relevant rules and documentation, reducing context cost and noise while improving consistency.
• Created a behavioural reverse-engineering workflow in which agents authenticate, exercise the legacy product like users, capture screenshots and interaction video, and document expected behaviour before implementation.
• Introduced human-in-the-loop review, playable preview deployments, and product-manager video walkthroughs so interaction feedback arrives without requiring developers to demo every feature live.
• Kept legacy and new implementations moving safely through an iframe-based microfrontend boundary while the team pivoted from the earlier migration phase.
• Built an SVG export pipeline that maps hard-coded colours to design tokens, generates light and dark theme values, and detects visually duplicate icons even after designers rename them.
• Established a feedback loop where implementation reviews improve the underlying documentation, making future agent output more reliable.

Maintained and modernised the primary web platform for a major US healthcare provider, working across Drupal-backed content systems and reusable frontend components.

• Built reusable UI components for a Drupal-backed enterprise web platform.
• Developed search experiences using React and modern frontend tooling.
• Worked across Drupal 6, Drupal 7, and Drupal 8 upgrade paths for large content platforms.
• Planned and executed a Drupal 7 to Drupal 8 migration in under one year while keeping Lighthouse performance scores above 80.
• Delivered AngularJS-to-React modernisation work for search and content experiences.
• Created a sitemap-driven visual regression tool that reduced manual testing effort by roughly 2000 hours.

Built web-based learning applications, widgets, and tooling using HTML5-era browser capabilities, JavaScript frameworks, testing, and CI/CD.

• Built applications, widgets, and tools for web-based learning using HTML5, JavaScript, jQuery, and AngularJS.
• Migrated legacy Flash and Java applet learning experiences to JavaScript-based browser applications.
• Added unit testing through Karma and Jasmine and contributed to CI/CD implementation.
• Developed a Flash-to-HTML5 conversion tool that supported migration of more than 15000 widgets.

A model-agnostic engineering operating model combining institutional knowledge, context routing, legacy behaviour discovery, automated environments, human review, and evidence-based delivery.

• Piloted the strategic shift from assistant-based coding to an AI-first delivery system and scaled it after proving safety and repeatability.
• Routed minimal task-specific context to different models to lower cost and improve output quality.
• Made running-product behaviour the migration specification through automated login, guided exploration, screenshots, videos, and markdown evidence.
• Automated preview deployment and review evidence, then fed human findings back into the documentation used by future agents.

Architecture direction for customer-facing and internal fleet-management dashboards with legacy coexistence, Angular modernization, routing, state, i18n, and release discipline.

• Defined boundaries for feature-heavy dashboards where maps, alerts, tables, permissions, video, and operational workflows must coexist.
• Led AngularJS-to-modern-Angular modernization across multiple Angular generations without freezing product delivery.
• Established routing, component ownership, state models, and validation practices that make large product surfaces easier to change.
• Created release-readiness tooling and targeted checks so teams can ship dashboard changes with stronger confidence.

Design-system foundations and component governance for dense SaaS dashboards where reusable patterns must preserve product meaning, accessibility, and visual consistency.

• Defined component APIs around product language instead of styling switches, so templates read like workflow decisions.
• Connected design tokens, Figma usage, theme foundations, accessibility, and reusable component patterns into delivery standards.
• Reviewed designs and implementation plans for consistency, responsive behavior, and long-term maintainability.
• Balanced reusable primitives with product-specific patterns so the design system speeds delivery without flattening important differences.

Performance and interaction architecture for map-heavy, video-heavy, alert-driven dashboards where users need real-time context without losing scanability.

• Designed UI structures for live alerts, map-heavy workflows, video playback, large datasets, dense tables, and repeated operational actions.
• Kept expensive transformations out of repeated render paths and made loading, stale, partial, and error states explicit.
• Pushed map and alert experiences toward clearer aggregation, better backend contracts, and more useful product states.
• Focused performance work on user trust: stable context, predictable actions, fast scanning, and recoverable failures.

Cross-functional product and architecture work that turns workflow problems into better UI behavior, backend contracts, search strategy, and team standards.

• Reframed timezone handling as a product and platform concern rather than a local formatting issue.
• Proposed i18n workflow improvements that reduce translation drift and make runtime behavior easier to verify.
• Identified backend-query and API-contract improvements from frontend workflow pain points.
• Used problem-observation-proposal-impact framing to move product decisions beyond ticket-by-ticket implementation.

Repository-level standards, documentation, code review practices, and automated checks that help engineers and coding agents ship with stronger consistency.

• Defined architecture guidance, development rules, and context-routing documents that make repository ownership easier to understand.
• Added custom ESLint, SonarQube, code-review, and validation checks for high-risk frontend changes.
• Built team workflows for design review, implementation review, and AI-assisted verification.
• Mentored engineers through reusable examples, PR review patterns, and clearer standards for component and route ownership.

Career-long modernization track record upgrading legacy application estates across learning platforms, healthcare content systems, and fleet-management dashboards.

• Moved browser learning experiences from Flash and Java applets to JavaScript and HTML5.
• Worked through Drupal 6, Drupal 7, and Drupal 8 transitions for large content platforms.
• Modernized AngularJS applications into React and modern Angular generations.
• Built automation, testing, and quality gates around migrations so teams could move faster without losing reliability.

Educational looping-adder computer that makes the path from analog input to digital output visible at one instruction per second.

• Modelled two 0-9 rotary potentiometers through 0-5 V, raw four-bit ADC codes, and decoded input digits, with both ADC stages visible on the breadboard.
• Runs a real compiled loop that samples both knobs, adds them in the ALU, drives twin seven-segment displays from 00-18, and branches back to sample again.
• Preserves drill-down views for the compiler, CPU, registers, memory, ALU, breadboard, transistors, and execution timeline.
