Who I Am
About Glen Pais
Senior Full Stack Developer Canada — 12+ years React, Next.js, Angular, TypeScript. Open to senior roles across Canada.
My Journey
With 12+ years of experience building everything from high-performance single-page applications to enterprise-scale e-commerce platforms at Loblaws, I specialize in designing and developing scalable, performant, and accessible web applications that deliver exceptional user experiences.
My expertise spans modern frontend architecture, including Microfrontends, Server-Driven UI (SDUI), and scalable design systems. I focus on building maintainable architectures that enable independent teams to ship faster while ensuring consistency, reliability, and long-term scalability.
Performance is a core part of my engineering approach. I optimize applications for Core Web Vitals, Lighthouse, accessibility, bundle size, rendering performance, and SEO—creating fast, resilient experiences that scale to millions of users.
I also embrace AI-native development workflows, using Cursor, GitHub Copilot, v0, and MCP Servers to automate repetitive tasks, accelerate delivery, improve code quality, and spend more time solving complex engineering challenges.

Work Experience
Loblaws
Driving frontend platform strategy at Loblaws Digital across multiple product teams — owning microfrontend architecture, Core Web Vitals standards, and scalable performance infrastructure while embedding AI-assisted development practices organization-wide.
- Architected Module Federation-based microfrontends for retail applications and integrated MCP servers for internal engineering workflows, enabling independent team delivery with secure tool orchestration
- Built a production RAG pipeline for developer knowledge retrieval, improving answer relevance and reducing time-to-resolution by grounding responses in internal docs and code context
- Established prompt engineering standards and reusable prompt templates (including rules.md guardrails), improving consistency, safety, and output quality across AI-assisted development tasks
- Improved web performance through chunk splitting and lazy loading strategies while enforcing Core Web Vitals (LCP, INP, CLS) targets, reducing latency and maintaining high Lighthouse scores
Infosys
Served as a technical anchor across multiple client engagements, leading cross-functional teams to deliver high-performance e-commerce platforms while establishing scalable frontend architecture standards across the delivery unit.
- Designed and scaled a shared component library across 8 client projects, cutting average feature delivery time by 30% while enforcing performance and design consistency
- Acted as technical lead on a high-visibility retail replatforming project — introduced performance budgets and Web Vitals monitoring, improving average page load time by 45%
- Pioneered SSR and SSG as org-wide standards, measurably improving SEO scores and eliminating render-blocking bottlenecks across multiple client properties
- Optimized bundle sizes by 25% through custom Webpack configuration and code splitting strategies, directly improving scalability under high-traffic loads
Bolas Intelli Solutions Ltd
Built full-stack web applications and APIs for enterprise clients, taking end-to-end ownership of features from architecture through deployment.
- Engineered reusable UI components and data-driven directives in Angular, forming the foundation for the company's internal component framework
- Designed and implemented RESTful APIs with Express.js and PHP, enabling seamless integration between frontend products and backend data sources
- Resolved critical cross-browser compatibility issues through systematic polyfill strategy, reducing browser-related customer complaints by 10%
- Improved page responsiveness and frontend reliability by profiling rendering bottlenecks and introducing targeted performance optimizations across core user flows
