What I'm looking for

I’m looking for remote B2B opportunities across Europe where I can build secure Salesforce solutions for enterprise or financial domains, deliver reliable integrations, and modernize platforms with a strong QA-driven mindset.

I’m a results-driven Salesforce Developer with 4 years of hands-on platform experience and a strong background in QA. I specialize in secure solutions for the financial and enterprise sectors, backed by Salesforce certifications including Platform Developer II.

In my current role, I engineer custom, high-performance Lightning Web Components (LWC) and build secure Experience Cloud portals tailored for banking and financial workflows. I architect robust Apex integrations, custom controllers, and triggers to ensure secure and seamless financial data flow between external systems.

I also bring a strong systems- and quality-minded approach from my Salesforce QA experience. I’ve designed and maintained automated test suites using Provar, SoapUI, and Postman (REST APIs), and supported automation with Selenium, Jenkins, and Azure DevOps—so releases land with confidence.

Beyond development, I streamline operations through Salesforce Flow—building complex automation to reduce manual overhead and improving environment configurations and data models for international clients. I’m available for remote B2B contracts across Europe, especially where security, integration reliability, and modernization matter.
