About Deepak
Fractional UI Architect
Glasgow, United Kingdom - 12:45 am local time
Overview: I am a Lead UI Engineer and Architect with over 11 years of experience specialized in building secure, high-performance web applications for the financial sector. I bridge the gap between complex technical architecture and seamless user experiences, having led major UI transformations for JP Morgan Chase and Barclays.
What I can do for you:
1. React/Next.js feature delivery + refactors (clean, scalable patterns)
2. Performance optimization (lazy loading, memoization, virtualization, code splitting)
3. Test automation (Jest, React Testing Library, Cypress; Maestro for mobile)
4. Fractional frontend architect support (PR reviews, standards, mentoring) — I’ve led and mentored a 4-engineer team.
Core Strengths & Skills:
1. Scalable Architecture: Expert in Micro-frontends (Vite Module Federation), Monorepos (Turborepo/Yarn), and Design Systems.
2. Accessibility & Compliance: Specialized in WCAG 2.2 AA standards and automated accessibility testing (Axe).
3. Efficiency Engineering: Proven track record in CI/CD optimization using Docker and Kubernetes to slash production times.
4. AI Enablement: Expert in Prompt Engineering to halve developer effort and accelerate delivery.
Selected Accomplishments:
1. JPMorgan Chase: Architected a Compliance Dashboard that cut end-user effort by 80% and reduced release cycles from 60 to 20 minutes.
2. AI Innovation: Integrated AI-assisted code generation that doubled engineering throughput on critical paths.
3. Barclays: Built an Internal Developer Knowledge Hub and shipped a regional iOS app surfacing innovative product ideas.
Whether you need to de-risk a complex migration, build a scalable design system, or optimize your frontend performance, I provide the senior leadership required to deliver enterprise-grade results.
Availability: 25 hrs/week. Preference: fully remote.
