Work Experience
Angular Expert
Dycom Industries, Inc.
- Led the development of a reusable Angular subframe UI component library to standardize and accelerate UI development across Dycom’s legacy and modern applications.
- Collaborated closely with the UI/UX team to align Figma designs with Angular implementations using Figma Code Connect for consistent design-to-code integration.
- Provided developer-driven feedback to influence design decisions, improve component usability, and ensure long-term maintainability.
- Documented technical processes, component design patterns, and solutions to support ongoing library development and knowledge transfer.
- Used a modern CSS framework with no libraries, such as mixins, CSS variables, etc., to build libraries.
- Architected and led a company-wide Angular component library adopted across 2-3 front-end teams, cutting redundant development time by over 25% and bringing consistency to a codebase that previously had no shared standards between teams.
- Migrated critical components to RxJS Signals, reducing unnecessary change detection cycles in production and eliminating XSS and dependency vulnerabilities that posed active security risks to the application.
- Established and documented front-end development standards from scratch across cross-functional teams, replacing inconsistent team-by-team practices with a unified approach to architecture, code quality, and delivery.
- Embedded Jest unit testing as a non-negotiable part of the development workflow, ensuring every component is verified before it reaches production.
- Owned end-to-end CI/CD pipelines in Jenkins, giving the team reliable, repeatable build and deployment processes they could trust.

Experience
Pharvios
https://pharvios.com/I lead engineering on the product, working closely with our product lead and UX researcher, who ran discovery sessions with pharmacy owners and counter staff. Much of the data model came from those sessions rather than from a spec.
On the back end, I designed the multi-tenant model in PostgreSQL with strict tenant isolation and built the REST API layer in NestJS, including role-based access control and a per-branch audit trail, since dispensing is regulated and every sale has to be traceable. On the front end, I built the Angular application covering point of sale, batch and expiry level inventory, prescriptions, multi-branch reporting, and a branded online storefront, each tenant gets on its own web address, using Signals and RxJS for reactive data flows.
I also own the GCP infrastructure, CI/CD, and the release process that comes with it.
CropSights
https://cropsights.wilburellis.com/HomeRx Africa
https://homerx.africa/I contributed to building and maintaining key parts of the web application, with a strong focus on front-end architecture, performance, and accessibility. On the back end, I worked on services that support medication discovery and AI-driven prescription analysis, helping to identify potential risks and interactions and providing guidance to support safer medication use. I collaborated closely with product and design to translate complex healthcare workflows into intuitive, user-friendly experiences while maintaining strong data privacy and data integrity standards. The platform was built using a modern, scalable architecture, enabling iterative delivery, rapid learning, and long-term maintainability as the product evolved.
Command Keeper VsCode Extension

• Export and Import Commands: Easily backup or share your saved commands as a JSON file.
• Keyboard Shortcuts: Quickly access features with customizable keybindings.
Subframe Angular Library
I owned the architecture and the public API surface, which is the part that matters most in a shared library, since every decision becomes something other teams depend on and cannot easily be walked back. Subframe ships 30+ components across forms, navigation, overlays, data display, and feedback, including date and time pickers, steppers, guided tours, paginated tables, and charts.
I built the packaging and distribution workflow with ng-packagr, managed peer dependencies and version compatibility across consuming applications, and wired releases into the CI/CD pipeline through Jenkins so teams could pull updates without manual steps. Test coverage was written alongside the components with Karma and Jasmine rather than bolted on afterward.
The library outlived my engagement on the project.
PoScrub
http://app.poscrub.comI lead engineering on the product. The core problem is classification rather than search, since keyword matching constantly flags the wrong things. The system evaluates each post in context through an LLM and returns a plain-language reason for every flag, which the user reads before deciding. Nothing is ever deleted automatically.
On the back end, I built the NestJS API, the OAuth integration with the X API, and the ingestion pipeline that pulls and evaluates long post histories. Posts are processed in memory and never stored, which was a hard constraint from the first design session and shaped the entire architecture. On the front end, I built the Angular review interface for scanning, filtering by time range, and bulk action on flags.
Privacy requirements, including GDPR and CCPA alignment, were designed in from the start rather than retrofitted.
SpotDraft
https://www.spotdraft.com/Made4KidsNG
http://made4kidsng.com/Role and contributions:
• Led a cross-functional team of three developers and a designer to build and launch the application from inception to production.
• Acted as product manager and full-stack engineer.
• Designed and implemented the majority of the front end, delivering interactive, responsive UI and UX tailored to family-oriented shoppers.
• Built approximately 55% of the back-end services, including core APIs, business logic, and data models.
• Developed with modern technologies such as NestJS, PostgreSQL, Prisma ORM, and Supabase, ensuring robust performance and scalable data architecture.
• Managed sprint planning, task distribution, and team coordination to meet delivery milestones reliably.
