Frontend.Next.js.TypeScript.React.
I build structured, performance-minded web interfaces with Next.js (App Router), React and TypeScript.
Backend exposure: Spring Boot CRUD + SQL (junior level, actively improving). Ninan Studio is my personal label — I apply as an individual developer.

ABOUT
Frontend developer with strong delivery focus.
I’m Cesar Pumayalla — a developer focused on frontend (Next.js / React / TypeScript). I care about clean UI architecture, performance, and accessibility, with a minimal editorial approach that supports content rather than marketing.
My background is non-traditional (marketing → digital → product/innovation), and I transitioned into development through bootcamps and hands-on projects. I also have backend exposure (Spring Boot CRUD + SQL) and I’m building full-stack skills without overstating my level.
Core: Next.js (App Router), React, TypeScript, Tailwind
Quality: semantic HTML, performance mindset, WCAG basics
Tooling: Git/GitHub, Vercel CI/CD, DNS/domains, basic security
Backend exposure: Spring Boot REST + SQL (junior, improving)
WORK
Work
A small set of projects that show how I build: structure, readability, performance, and real delivery.
More code samples and context available on request.
CAPABILITIES
What I build
I’m applying as a frontend developer. These are the areas where I deliver reliably — without agency positioning.
HOW I WORK
Clarify scope → define a clean structure
Build with predictable components and typed interfaces
Ship, validate, iterate (performance + UX details)
Targeting frontend roles (Next.js/React/TS). Backend is positioned honestly as exposure and improved through a focused full-stack project.
PROCESS
How I work
A simple workflow that mirrors team work: clarity first, then delivery and iteration.
Focus: maintainable structure, predictable UI, and shipped results.
