Madly Heaven

Full-stack engineer with 4+ years building production fintech and banking software for Lloyds Banking Group (Halifax & Birmingham Midshires brands) via Tata Consultancy Services — shipping 5+ live SPAs used by brokers and customers.

I specialize in React.js, Redux, TypeScript, and Node.js/Express.js, with hands-on experience in micro-frontend architecture (Shell & Shared Repository pattern), RESTful API design, and MongoDB. I've built mortgage affordability calculators, rental income tools, product search engines, and a foreign-currency microservice that opened mortgage eligibility to international earners (INR, AUD, EUR).

Measurable impact: 100% unit test coverage (Jest, React Testing Library), ~30% faster page loads via lazy loading and memoisation, ~35% lower API response times through caching, and a 90% cut in manual effort after automating a PDF catalog pipeline. I also resolved a critical production incident in under 4 hours, earning direct client appreciation.

Beyond code, I'm the sole code reviewer for teams of up to 9 engineers, mentor junior developers, and enforce WCAG accessibility and clean-code standards (ESLint/Prettier pre-commit gates) on every release. I hold Microsoft Certified: Azure AI Engineer Associate and Azure Developer Associate certifications and I'm comfortable owning a feature end-to-end — architecture through CI/CD deployment on Azure DevOps.
