Génesis Guerrero

I started as a freelancer and later co-founded Genobyte, a two-developer studio in Puerto Vallarta focused on tourism, to work on bigger projects.

• I lead the development of a React and Supabase platform for an international organization that funds community projects. Phase 1 is done and we are now working on phase 2.
• I maintain the website and booking engine of a vacation rental company (Laravel, Vue, MySQL), with CI/CD on GitHub Actions for staging and production.
• I built a tour booking system with online payments and check-in for a tour company, using Next.js and Stripe.
• I built the MVP website for a vending machine business with Next.js.
• I manage the full process with clients and partners: requirements, quotes, development, deployment and support.

Selection program for a Software Engineer position. I completed the program; the company did not open the position because of budget changes.

• I built an internal full stack app with Laravel and Angular to run pre-approved, parameterized SQL queries on external databases.
• Cookie-based session authentication, role-based access control and a SQL validation layer with the Strategy pattern to block unsafe queries.
• I worked with TDD and PHPUnit; in the last month I joined a production team and completed tickets following the full workflow.

• I built complete websites and improvements for the chain’s 3 hotels, 3 spas and 6 restaurants, plus the sites for travel agents and the vacation club, with Laravel, Vue, JavaScript and MySQL.
• I automated sitemap generation, including dynamic CMS pages (blog, offers and rooms), to improve indexing.
• I built a sports prediction game for a seasonal offers campaign.
• I handled the web side of the Hot Sale campaign defined by marketing, from design to deployment.

I joined an existing team to deliver the project on time.

• In 3 months, I led the development of a user and financial transactions system integrated with the TOKA API (cards and e-wallets).
• I built the transactions module: deposits, deductions, transfers, balance checks and card linking.
• I implemented hybrid login (LDAP and own database), password recovery, roles, permissions and dynamic modules.

I joined an existing team to deliver the project on time.

• I built the backend of a corporate social network with Supabase: real-time feed, posts, comments, likes, post location, groups and invitation codes.

• I wrote migrations, PostgreSQL functions and Edge Functions with Deno, and documented the API for the frontend team.
• I built the backend of a B2B dashboard where client companies managed their employees and groups.

• I connected website forms to lead nurturing for email marketing, and I segmented audiences.
