    I have extensive experience with the Angular 2+ framework, having worked with two companies to design and implement scalable front-end solutions. These collaborations allowed me to contribute meaningfully to modernizing and optimizing user interfaces. Alongside Angular, I have a strong background in managing WordPress sites, including setup, migration, maintenance, and performance tuning. Understanding the critical importance of SEO for commercial platforms, I’ve also successfully leveraged Google Ads (AdWords) to increase client visibility in search rankings. On the backend, I specialize in Java Spring Boot, which has served as the backbone for my RESTful service development. I’ve built and maintained cloud-integrated APIs that seamlessly interact with Angular-based front ends, ensuring smooth, high-performance user experiences. My cloud development expertise includes AWS, where I’ve created resilient, cost-effective infrastructure solutions. I’m also well-versed in Kubernetes, orchestrating containerized applications with a focus on efficient deployment, scaling, and automation. In all my projects, I work closely with product owners to align development efforts with clear business goals, always adhering to a well-defined 'definition of done.' My combined skills across Angular, WordPress, SEO, AWS, Java Spring Boot, and Kubernetes enable me to deliver full-stack solutions that are innovative, scalable, and strategically aligned with client needs.

    Senior Full Stack / Serverless Engineer specializing in migrating from legacy code, working in polyglot (multi-language) environments, and protecting data integrity. I build modular, testable, and scalable systems that guarantee the integrity of your data, ensuring it can keep up with all your business needs. I have driven the migration of large-scale enterprise applications from legacy implementations to modern, cloud-based architectures while ensuring no loss of data in flight and minimizing downtime. As business needs change, technologies evolve, and developers leave a team, you must get to a robust, easy-to-maintain, well-documented codebase. Without institutional knowledge of the history behind each design decision, you can wonder how to escape a chaotic situation without affecting your end users. I bring a systematic approach to navigating these kinds of projects. Whether this is where your system is now, or you're starting something new and want to ensure you keep up with best practices from the start, working with me will ensure you end up with maintainable, thoroughly tested, clearly documented, and stable code. I will start by getting to know your business needs and technical requirements and, from there, develop a plan that divides your goals into clearly defined short-term milestones. My fixed-priced contracts ensure that your budget is not affected by surprises. At the same time, my agile approach to planning will keep things flexible enough to accommodate any shifting priorities.
