Danillo Gremes - Software Engineer

More About Me

I am a Software Engineer with a non-traditional background: for over 9 years, I was a business owner managing complex residential projects, budgets, and logistics. This experience taught me that software doesn't just need to work; it needs to solve real business problems.

After years of identifying operational bottlenecks that off-the-shelf tools couldn't fix, I transitioned to engineering to build the solutions myself. Today, I combine the grit and discipline of an entrepreneur with modern full-stack development skills.

Currently, as a Full Stack Engineer at Gremes Tech Solutions, I translate business needs into scalable web and mobile applications, ensuring every line of code drives real value.

Services I Provide

Comprehensive solutions for your digital needs.

Web Development

I craft responsive, high-performance websites using the latest frameworks like Next.js and React. From dynamic landing pages to complex web applications, I ensure pixel-perfect implementation, SEO-friendly architecture, and a seamless user experience across all devices.

Mobile Apps

I build cross-platform mobile applications for iOS and Android that feel native. Using technologies like React Native or Flutter, I deliver smooth animations, intuitive interfaces, and robust functionality, ensuring your app stands out in the App Store and Google Play.

Backend Architecture

I design and implement secure, scalable server-side systems. Whether it's RESTful APIs, GraphQL endpoints, or microservices, I optimize for speed and reliability. I handle database design (SQL/NoSQL), authentication, and cloud infrastructure setup on AWS or Google Cloud.

Performance Optimization

I audit and supercharge existing applications. My process involves deep code analysis to identify bottlenecks, improve load times, and enhance Core Web Vitals. I also focus on accessibility (WCAG compliance) and SEO best practices to maximize your digital reach.
