What I'm looking for

I’m looking to develop full-stack web applications using Java, Spring Boot, REST APIs, databases, and React/TypeScript, creating efficient, scalable solutions aligned with business needs.

On Workana, I develop e-commerce and multi-tenant SaaS platforms with Spring Boot, PostgreSQL, and React. I also work on omnichannel CRM systems with messaging integrations, including WhatsApp, and catalog synchronization between platforms.

I build real-time web applications using WebSocket to synchronize frontends and backends, and create Python automations and web scraping for operational data. My projects include MedCota, a full-stack purchasing and quotation management application, and NetSpeed, an internet speed test with live progress and a results history.
