How I work
Clear planning, incremental delivery, and early feedback. I collaborate with design and business to build solutions that are useful, not just pretty.
AI as support
I use AI as a copilot to speed up research, validate approaches, and improve quality, always with critical review and technical responsibility.
Dear Hiring Team:
I’m applying because I enjoy building digital products that solve real needs. I bring visual judgment, technical focus, and commitment to results. I’m organized, communicate well, and stay focused on delivering value in every iteration.
In my recent projects I built complete solutions across different domains: e-commerce with Clerk auth and E2E-tested checkout, a live cultural community site delivered as a client commission, and an interaction-heavy job board. These experiences strengthened my ability to deliver tested, CI-backed code with clear architecture and reliable user flows.
Mini Ecommerce
Clerk auth, typed HTTP client, SSG/ISR catalog, Prisma + Postgres orders, Sentry error boundaries, Playwright checkout E2E in CI.
Saravá Espacio Cultural
Client commission: live Next.js site with JSON content, hero carousel, and static export to GitHub Pages.
Mini Job Board
Vanilla JS with search, multi-filter, saved jobs, and CI with schema validation.
AI Stories
Serverless story generator with client HTTP resilience, 402 handling, and local fallback stories.
Portfolio
Hand-coded bilingual site with i18n and responsive project case studies.
I’m ready to add value from day one with a continuous-improvement mindset. My workflow includes automated testing (Vitest, Testing Library, Playwright), CI/CD with GitHub Actions, and deploys on Vercel and GitHub Pages.
Sincerely,
Alejo Castillo González
