What I'm looking for

I seek a Salesforce development role focused on building scalable CRM solutions, integrations, and automation in a collaborative team that values quality, user adoption, and professional growth.

I am a Salesforce-focused developer and certified Platform Administrator with hands-on experience building custom applications using Apex, Visualforce, Lightning components, and Lightning Web Components. I design scalable solutions, manage data migrations and third-party integrations, and implement workflow automation to improve business processes.

My background includes full-cycle Salesforce implementations, unit testing and code reviews, and delivering end-user training and documentation to ensure successful adoption. I have also developed custom CRM systems and standalone applications using Java, and worked in technical support and security systems consulting roles.

I am motivated by building user-friendly, maintainable systems that streamline operations and deliver measurable efficiency gains, and I bring a pragmatic, quality-focused approach to development and deployment.
