What I'm looking for

I’m looking for a Senior Full Stack role where I can build Java/React/Angular features, automate business processes, and work with AWS and modern CI/CD. I want teams that value clean architecture, maintainability, and fast iteration on data-driven systems.

I’m a Senior Full Stack Developer building and maintaining complex web systems where automation and large datasets are the norm. I work across the full stack—designing frameworks, implementing business-process logic, and shipping reliable features for multiple client environments.

My background combines strong Java expertise with modern frontend development using ReactJS and Angular/AngularJS. I’ve delivered portal and BPM experiences (including Camunda BPM task/project maintenance), created many custom forms and automation flows, and used RegExp-heavy processing to extract and normalize information from PDFs, emails, and varied text inputs.

I also bring backend and platform skills for production-grade delivery: Spring Framework/Spring Boot, JPA/Hibernate, MySQL and PostgreSQL, AWS (including bucket/file manipulation), Docker-based packaging, and disciplined versioning with Git/GitHub. From SaaS process automation to GIS-style geolocalization work (Canvas/OpenLayers), I’m focused on building maintainable systems that teams can extend with confidence.
