What I'm looking for

I am looking for a role that values collaboration and innovation, offering opportunities for growth and impactful projects.

I am a Technical Product Owner and Senior Web Developer with over four years of full-stack experience, including two years in lead developer roles. My expertise lies in bridging technical and business requirements through effective stakeholder management, ensuring that both technical and non-technical teams are aligned on project goals. I excel in translating complex technical concepts into scalable solutions that meet client needs.

At Granicus, I utilize my advanced skills in React, Node.js, Next.js, TypeScript, and MongoDB to build and optimize web applications. I serve as the primary technical liaison between development teams and key client stakeholders, ensuring that project requirements are met and deliverables are aligned. My role also involves collaborating with sales, marketing, and customer success teams to provide technical consultation and support throughout the project lifecycle.

As a Lead Developer at Simpleview Inc., I successfully led a major migration project for our largest client, resulting in significant cost reductions. I have also spearheaded an Agile transformation initiative within the company, earning my PSM I and PSPO I certifications. My commitment to mentoring and developing my team has accelerated productivity and fostered individual career growth.
