About Roylan

With over 10 years of professional experience, I have developed robust and scalable web solutions for companies in various sectors: tourism, fintech, e-commerce, and intelligent communication systems. I have worked on projects for tourism platforms, accounting management systems in AWS, omnichannel chatbots with AI, and high-traffic booking portals.

Throughout my career, I have held roles as a Full Stack developer, technical frontend lead, and cloud infrastructure administrator (AWS), always focused on optimizing performance, improving user experience, and delivering clean code with scalable architectures.

Currently, as a freelancer, I work on Full Stack development projects and also offer technical consulting for teams that need to optimize their applications or migrate technologies.

My main stack includes Python (python developer) with Django, Flask, and FastAPI for backend, and JavaScript (JS) with Vue.js, React, Quasar, Typescript, and AstroJS for frontend.

On the backend, I handle SQL databases, MySQL, and Supabase. For asynchronous tasks and queue management, I use Celery and Redis.

I have implemented complex integrations such as:

  • Omnichannel connectors with WhatsApp Business, Telegram, and LiveChat using webhooks and Django Channels.
  • Calendar synchronization with Booking and TripAdvisor using iCal technology
  • Payment gateways with Stripe and Paycomet
  • REST APIs for communication between services
  • I also have experience in cloud infrastructure, mainly AWS (EC2, S3, RDS, Lambda), and in DevOps tools like Docker, CI/CD, and Linux server administration.

I have led technical migrations and optimizations that have reduced loading times by 40%, improved retention rates by 25%, and accelerated financial closings by 15%.
