Open to new roles

I build web apps that load fast and work for everyone.

I'm Shikha Mangal, a senior software engineer with 7 years of experience in React, Next.js and TypeScript. I've shipped healthcare and e-commerce products for Johnson & Johnson, BlueCross BlueShield, Driscoll's and Redington.

Frontend engineer, seven years in.

I turn product ideas into fast, accessible web applications and help the teams around me do the same.

I started in 2019 as a full-stack engineer at a health-tech startup, building wayForward, a SaaS platform that matches people with psychologists. It was acquired by DarioHealth in 2021.

From there I moved into client work at Enquero Global and Publicis Groupe, building an SEO-focused website, internal data tools and an e-commerce portal for 50,000+ monthly users.

Most recently, at Perficient, I led frontend delivery for enterprise healthcare clients including Johnson & Johnson and BlueCross BlueShield. I shipped 15+ releases, improved Core Web Vitals by 30%, and guided frontend architecture, code reviews and mentoring for a team of 8.

How I work

Performance is a feature
I measure Core Web Vitals before and after changes, and choose SSR, SSG and code-splitting based on what the numbers show.
Accessibility from the first commit
Semantic HTML, keyboard support and WCAG checks are part of building a component, not a final pass.
Reviews that help people grow
I review code to share context, not just catch bugs, and mentor engineers on the decisions behind the code.
Comfortable working remotely
I have worked fully remote with product, design, QA and engineering teams for several years.
