Full Stack Developer focused on building modern and scalable applications.
Hi, I'm Cristofe Albuquerque. I build end-to-end solutions — bridging fluid interfaces in Next.js with robust NestJS backends, relational databases, and production deployments.
Software engineering focused on architecture, security, and real-world production.
My core foundation is in frontend engineering, crafting fast, responsive, and polished interfaces with Next.js, React, and TypeScript.
Expanding this background into the full stack ecosystem, I build structured NestJS APIs, model PostgreSQL databases, and manage Docker deployments on Linux and Cloud servers.
I focus on clean code, well-defined data contracts with Zod, and decoupled architectures that keep codebases easy to maintain.
How I build applications
BFF Architecture & Modern Frontend
Next.js App Router integrated with enterprise APIs, hybrid rendering, and secure route handlers.
Authentication & Security
Granular RBAC access control, secure HttpOnly cookies, and end-to-end data protection.
Strict Typing & Validation
Strict TypeScript across frontend and backend, with real-time schema validation via Zod.
Containers & Infrastructure
Isolated environments with Docker Compose, Caddy reverse proxy, and optimized video streaming.
Technologies I use daily
Tools and technologies in which I have practical hands-on experience to create resilient, fast, and secure applications from UI to deployment.

Featured Applications & Projects
End-to-end applications — from relational data modeling and enterprise APIs to modern, responsive interfaces.
LMS — Next.js Frontend
Educational platform built with Next.js App Router and BFF architecture. Focused on end-to-end security, efficient on-demand media playback, and a fluid, responsive user experience.
- •HTML5 video player with HTTP Range Requests support (206 Partial Content)
- •HttpOnly cookie authentication with SameSite and edge middleware
- •BFF architecture with strict real-time schema validation via Zod + React Hook Form
- •Atomic state management with Zustand and modular styling with SCSS Modules
LMS — NestJS Backend
Scalable enterprise API built with NestJS and PostgreSQL, focused on high-performance secure streaming, domain-driven architecture, and advanced security.
- •On-demand streaming (HTTP 206) protected and offloaded by Caddy via X-Accel-Redirect
- •Granular RBAC access control, secure __Secure-sid cookie sessions, and Argon2id + Salt + Pepper hashing
- •Automated testing with Vitest and relational data modeling in PostgreSQL with Prisma ORM
- •Container orchestration with Docker Compose, health checks, isolated networks, and optimized multi-stage builds
Personal Portfolio
Modern web application built with Next.js 16 to showcase projects and engineering experience, featuring native multilingual support and automated tests.
- •Static Site Generation (SSG) and native i18n (PT/EN) with next-intl
- •Automated component and utility testing with Vitest and Testing Library
- •Continuous integration (CI) pipeline with GitHub Actions and Schema.org SEO
LMS — Express API
First version of the platform API built with Express and TypeScript. Served as the validation foundation for the subsequent structured migration to the NestJS ecosystem.
- •RESTful API with typed TypeScript routes and JWT authentication
- •Relational PostgreSQL data modeling and direct SQL queries without ORM
- •Core study foundation that guided architectural decisions in NestJS
