Engineering digital ecosystems from architecture to accessibility.
A fullstack engineer's role is to be a
trustworthy host, ensuring every user
has a fast and accessible experience.
Some words
Hey there! I specialize in mission-critical systems for fintech and digital
banking, architecting resilient backends with DDD/Clean Architecture
while ensuring the products they power are inclusive, lightning-fast,
and legally secure.
My expertise spans the entire stack — from accessible, WCAG 2.1/2.2
(AA/AAA) compliant interfaces built with Next.js 15 and React, to
event-driven backends with NestJS, Kafka, and RabbitMQ.
On the cloud side, I design infrastructure as code on AWS with
Terraform, provisioning Lambda, API Gateway, DynamoDB, and S3
with CloudFront — I am currently preparing for the AWS certification exam.
I delivered banking modules (Pix, TED, onboarding) 3 weeks ahead of
schedule, and I am an IAAP WAS Candidate currently pursuing an
M.Sc. in Computer Science at UFBA.
I'm looking forward to collaborating and creating something great!
Marvin Rocha.
Accessibility & Compliance
With a focus on inclusion and legal compliance, I build interfaces that meet
WCAG 2.1/2.2 (AA/AAA) and ADA/Section 508 standards from day one, reducing
legal exposure while reaching every user.
Architecture & Performance
I architect resilient backends with DDD/Clean Architecture and event-driven
systems, while optimizing Core Web Vitals on the frontend. From Next.js 15 to
NestJS and Kafka, I deliver systems built to scale.
Data, AI & Cloud
I design data layers and deploy AI-driven features that reduce manual work,
backed by cloud infrastructure as code on AWS (Terraform, Lambda, API Gateway,
DynamoDB, S3 & CloudFront) — currently preparing for the AWS certification exam.
Development Lifecycle
I approach fullstack development with a focus on creating accessible, high-performance,
and efficient web applications. Each project follows a methodical
plan to assure it exceeds standards of quality and performance.
Workflow
My workflow for fullstack development is centered on teamwork, productivity,
and delivering high-quality code. I leverage the latest tools and techniques
to provide engaging and smooth user experiences.
