About me
I’m a software developer with over 2 years of experience, specialized in Frontend Development. As a Full Stack Developer, I love solving real-world problems through software that enhances lives or businesses.

Experience
Discover my journey through various companies in software development and teaching, from startups to established tech enterprises.
Cloud Legion
I contributed to the design and development of Full Stack software solutions, working with Javascript and technologies like NextJS, Redux, TailwindCSS, ExpressJS and NodeJS. Our team utilized tools such as Docker, Sentry.io, and CI/CD pipelines on Azure to ensure high-quality and secure code. Additionally, we collaborated closely with the client's team, providing training and tech talks on the newly implemented technologies, their functionality, and usage. We also helped them adopt Scrum and deliver sprint demos.
MUSURE world
At MUSURE, a startup dedicated to creating innovative digital solutions, we developed a click-to-earn game and a 3D content creation tool designed to help content creators monetize their work. Contributing to both Frontend and Backend development, we used technologies like JavaScript, React, Redux, TailwindCSS, NodeJS, Firebase and Moralis. We collaborated closely with UX/UI and economics teams under the Scrum methodology, tackling challenges related to cryptocurrency integration and Web3.
Henry
I supported new students by guiding them through real-time JavaScript challenges and instructing them in GIT flow to prepare them for the bootcamp. I also collaborated on improving the bootcamp entry procedures.

NEXUS
A multilingual appointment booking and business management platform for service businesses.
Why it matters
Service businesses often spend time managing bookings manually (messages/calls, reschedules, no-shows). NEXUS streamlines scheduling for businesses and enables clients to self-book in just a few steps — across languages.
Key highlights
- Two-sided product: business + client dashboards and flows.
- International-first: built with a 4-language UI (EN/ES/DE/FR) from day one.
- Real-world schedules: opening hours + special hours/holidays.
- Role-based business access and profile switching.
- MVP-first foundation designed to scale into analytics, payments, staff, and more.
