Hi, I'm Ritesh Kumar.
I'm a Frontend & UI Consultant and Frontend Architect with more than 14 years of experience in software development.
My experience spans modern frontend technologies, web applications, mobile applications, UI engineering, backend integration, technical architecture and development workflows.
I enjoy solving difficult technical problems, understanding complex systems and converting business requirements into practical, scalable digital solutions.
I work comfortably with startups, businesses, agencies and development teams — whether they need a complete solution, technical guidance, debugging support or an experienced consultant to strengthen an existing team.
I am available for remote consulting opportunities across the globe.
How I work
- Understand before prescribing. Recommendations start from your business goals, constraints and existing systems — not from a favourite stack.
- Explain the trade-offs. Every technical decision has costs. You get them in plain language so you can decide with confidence.
- Leave the team stronger. Documentation, clear patterns and knowledge transfer — so progress continues after the engagement.
