In my recent freelance work, I delivered a four-step Solar Farm Underwriting wizard used by major banks in the US, with project persistence and PDF/XLSX report exports. I also migrated date handling to date-fns, added regression tests, and fixed a timezone bug affecting map data.

At PureSoftware, I built reusable components for analytics and reporting applications and optimized agGrid interfaces, improving large-dataset rendering performance by 40%. Across my roles, I’ve worked on SaaS dashboards, API integrations, and full-stack features using Angular, React, Vue, and Node.js.
