I'm an IT engineer and Technical Business Analyst with experience in financial systems, application platforms, data flows and production-critical environments.
I am currently strengthening my technical profile through hands-on backend and data engineering projects focused on APIs, SQL, data ingestion, transformation, monitoring and cloud-ready architecture.
My goal is to move toward more technical roles around integration, data platforms, backend systems and eventually cloud/platform engineering.
- IT engineer with experience in banking, financial systems and application platforms
- Background in business analysis, production-critical systems and technical coordination
- Interested in backend systems, APIs, SQL, data pipelines and distributed architectures
- Building practical projects to strengthen my engineering skills
- Previously explored blockchain and DeFi through smart contract and dApp projects
I am currently focusing on:
- Backend development with Node.js and Express
- REST API design
- SQL and PostgreSQL
- Data ingestion and transformation pipelines
- Redis caching
- Docker and local infrastructure
- Testing with Jest
- GitHub Actions CI
- Cloud architecture fundamentals, especially AWS
MarketPulse is a backend/data engineering learning project that simulates a production-grade data pipeline.
It ingests external market data, stores raw payloads, transforms them into structured PostgreSQL records, exposes them through a REST API, caches latest values in Redis, and tracks the ingestion lifecycle through logs and database records.
Key concepts demonstrated:
- External API ingestion
- Raw data storage
- ETL-style transformation
- PostgreSQL data modeling
- Data quality checks
- Ingestion run monitoring
- Redis caching
- REST API design
- Structured logging
- SQL diagnostics
- Unit testing with Jest
- GitHub Actions CI
- Docker Compose local infrastructure
- AWS architecture mapping

I am transitioning from a traditional IT Business Analyst profile toward a more technical path focused on:
- Technical Business Analyst roles
- API / Integration Analyst roles
- Data Flow / Data Platform Analyst roles
- Backend and data engineering-adjacent projects
- Cloud/platform engineering fundamentals
The objective is to build a stronger technical identity around systems, APIs, data flows, automation and cloud-ready architectures.
