Full StackDeveloper.From design to operations.

I’m Christian Alberto. Eighteen years designing and developing enterprise software for banking, telecommunications, healthcare, public administration and international e-commerce. Backend, frontend, systems architecture and the cloud infrastructure that sustains them.

01Profile

Working method and technical competence.

Full stack developer specialising in enterprise software. I design and implement backends in Java/Spring and Node.js, interfaces in Angular, React and Next.js, and the cloud layer on AWS and Kubernetes. Across banking, telecommunications, healthcare, the public sector and e-commerce, I apply the same architectural discipline end to end.

P·01

Backend as foundation

It is the domain in which I have accumulated the most experience: microservices, REST APIs, transactions and domain boundaries in Java/Spring and Node.js. The interface is essential; the system’s resilience, however, depends on the service that underpins it.

P·02

Genuine full-stack competence

It is not a superficial acquaintance with every layer. It means being able to address the data model, the endpoint and the form within the same working cycle — Angular, React or Next.js included — without dispersing resolution across several teams.

P·03

Production delivery, not demonstration

I deploy what I build: infrastructure as code, cloud servers and operational observability. A system cannot be considered complete until it runs in production, is instrumented and is available to its users.

02Capabilities

Eight areas of specialisation.

Backend, frontend, cloud, data, security, Web3, quality and artificial intelligence. Each area is grounded in years of production work, and together they cover a system’s full lifecycle: from initial design through to production release.

Area 01

Backend architecture

Microservices, REST APIs and asynchronous processing on Java/Spring and Node.js. Hexagonal architecture, clear domain boundaries and tests that allow the design to evolve with confidence.

Java
Spring Boot
WebFlux
Node.js
REST
Arq. hexagonal
TDD

Area 02

Application frontend

SPA, SSR and hybrid applications with Angular, React and Next.js on TypeScript.

Angular
React
Next.js
TypeScript

Area 03

Cloud & DevOps

AWS and Kubernetes in production environments: GitOps, infrastructure as code and observability.

AWS
EKS
Terraform
ArgoCD

Area 04

Data & persistence

Relational and NoSQL models, migrations and optimised reads through caching. From the schema to the index that reduces a query from seconds to milliseconds.

PostgreSQL
Oracle
MySQL
SQL Server
MongoDB
Redis
DB2

Area 05

Security

Protected enterprise APIs: authentication, authorisation, identity management and OWASP-aligned design. Security is incorporated at the design stage, not applied as a later remedy.

JWT
Spring Security
Keycloak
OWASP
IAM

Area 06

Web3 & blockchain

Smart contracts in Solidity, Web3 APIs and backends for decentralised applications on EVM networks.

Solidity
BNB Chain
Web3
DeFi
OpenZeppelin

Area 07

Quality

Unit, integration and end-to-end tests, together with quality gates that contain technical debt before it reaches the main branch.

JUnit
Mockito
Jest
Cypress
SonarQube
TDD

Area 08

Applied AI

Model-assisted development, embeddings and RAG in production services. The tool accelerates the work; architectural judgement is not delegated.

RAG

03Stack

Technologies in regular use.

Organised by layer, from the service tier to the blockchain. All have been applied in professional projects; they form the toolkit I use in day-to-day practice.

Service

The core of the system: where business logic, transactions and inter-service contracts reside. It is the layer in which I concentrate most of my experience.

Java
Spring Boot
Hibernate
Node.js
RabbitMQ

Interface

The layer with which the user interacts. Component architecture, state management and performance, always on TypeScript.

Angular
React
Next.js
TypeScript
JavaScript

Platform

The runtime environment. Containers, orchestration, infrastructure as code, and the observability that anticipates incidents before the user perceives them.

AWS
Kubernetes
Terraform
Docker

Data

The system’s persistence. Relational and document models, zero-downtime migrations, and the index that reduces a query from seconds to milliseconds.

MongoDB
PostgreSQL
Oracle
SQL Server
Redis

Security & quality

The two safeguard mechanisms: controlling access to each resource, and detecting failures before they reach the production environment.

JWT
Spring Security
OWASP
JUnit
SonarQube

Web3

On-chain contracts and wallet integration on EVM networks. Deployed and verified in production environments, not confined to testnets.

Solidity
Ethereum
Web3 APIs
OpenZeppelin

04Career

Eighteen years of professional practice across four countries.

From maintaining banking systems in Caracas to operating a global e-commerce platform in Madrid. Each stage contributed a distinct dimension: first development, then architecture, then the product, and finally the platform that sustains it.

DevOps Developer

Connecting Tech People S.L.

A year responsible for the continuous operation of a global e-commerce platform on AWS and Kubernetes (EKS), across development, test, staging and production environments. I implemented automated deployments through GitOps with ArgoCD, standardised infrastructure across all environments with Terraform, and optimised CI/CD pipelines to reduce build times. I also assumed operational visibility with Datadog and Sentry, and edge traffic rules with Akamai.
