P·01
Backend is my foundation
That’s where I have the most years: microservices, REST APIs, transactions and domain boundaries in Java/Spring and Node.js. The screen matters; what decides whether the system holds up is the service behind it.

Full StackDeveloper.From code to deployment.
I’m Christian Alberto. I have spent 18 years building enterprise software for banking, telecom, healthcare, public sector and global e-commerce. Backend, frontend, architecture and the cloud that holds it up.

01Profile
How I work, and what I master.
I’m a full stack developer with 18 years in enterprise software. I design and build backends in Java/Spring and Node.js, frontends in Angular, React and Next.js, and the cloud layer that holds them up on AWS and Kubernetes. Banking, telecom, healthcare, public sector and e-commerce: the same end-to-end architectural judgement.
P·02
Genuinely full stack
It isn’t knowing a bit of every layer. It’s being able to touch the data model, the endpoint and the form on the same day — Angular, React or Next.js included — without handing the bug between three teams.
P·03
Shipped, not demoed
I ship what I build: pipelines, Terraform, Kubernetes and observability on AWS. A system doesn’t exist until it’s in production, measured and in the hands of its users.

02Capabilities
Eight development fronts.
Backend, frontend, cloud, data, security, Web3, quality and AI. Each one backed by years of real projects, and together they cover a product’s whole path: from the first line of code to the production deployment.
Area 01
Backend architecture
Microservices, REST APIs and async processing on Java/Spring and Node.js. Hexagonal architecture, clear domain boundaries and tests that give you permission to change your mind.
- Java
- Spring Boot
- WebFlux
- Node.js
- REST
- Arq. hexagonal
- TDD
Area 02
Application frontend
SPA, SSR and hybrid apps with Angular, React and Next.js on TypeScript.
- Angular
- React
- Next.js
- TypeScript
Area 03
Cloud & DevOps
AWS and Kubernetes in real production: GitOps, IaC and observability.
- AWS
- EKS
- Terraform
- ArgoCD
Area 04
Data & persistence
Relational and NoSQL models, migrations and fast reads with caching. From the schema to the index that takes a query from seconds down to milliseconds.
- PostgreSQL
- Oracle
- MySQL
- SQL Server
- MongoDB
- Redis
- DB2
Area 05
Security
Protected enterprise APIs: authentication, authorization, identity management and OWASP-aligned design. Security gets designed up front, not patched at the end.
- JWT
- Spring Security
- Keycloak
- OWASP
- IAM
Area 06
Web3 & blockchain
Solidity smart contracts, Web3 APIs and backends for dApps on EVM networks.
- Solidity
- BNB Chain
- Web3
- DeFi
- OpenZeppelin
Area 07
Quality
Unit, integration and E2E tests, plus quality gates that stop technical debt before it reaches main.
- JUnit
- Mockito
- Jest
- Cypress
- SonarQube
- TDD
Area 08
Applied AI
Model-assisted development, embeddings and RAG in real services. The tool speeds things up; architectural judgement doesn’t get delegated.
- LLM
- RAG
- Agentes
- Embeddings

03Stack
The technologies I work with.
Grouped by layer, from the service to the chain. I have used all of them on real projects, not tutorials: this is the stack I work with day to day.
Service
The heart of the system: where business logic, transactions and the contracts between services live. It’s the layer I have spent the most years in.
- Java
- Spring Boot
- Hibernate
- Node.js
- RabbitMQ
Interface
What the person actually touches. Component architecture, state management and performance, always on TypeScript.
- Angular
- React
- Next.js
- TypeScript
- JavaScript
Platform
Where it all runs. Containers, orchestration, infrastructure as code, and the observability that warns you before the user notices.
- AWS
- Kubernetes
- Terraform
- Docker
Data
The system’s memory. Relational and document models, migrations without downtime, and the index that takes a query from seconds to milliseconds.
- MongoDB
- PostgreSQL
- Oracle
- SQL Server
- Redis
Security & quality
The two safety nets: who gets into what, and what breaks before it ever reaches production.
- JWT
- Spring Security
- OWASP
- JUnit
- SonarQube
Web3
On-chain contracts and wallet integration on EVM networks. Deployed and verified, not left on a testnet.
- Solidity
- Ethereum
- Web3 APIs
- OpenZeppelin

DevOps Developer
Connecting Tech People S.L.
A year keeping a global e-commerce platform running on AWS and Kubernetes (EKS), across development, test, staging and production. I implemented automated deployments with GitOps on ArgoCD, standardised infrastructure across every environment with Terraform, and tuned the CI/CD pipelines to cut build times. I also owned operational visibility with Datadog and Sentry, and edge traffic rules with Akamai.

I’m interested in projects where the backend and the product matter equally: cloud, enterprise systems and APIs that hold up under real load.
