Data Engineer · DevOps & Cloud

I migrate, validate and reconcile financial data for core banking and SACCO systems, and I run the Linux, Docker and PostgreSQL infrastructure it lives on. Most of my work is moving legacy SQL Server and Access data into PostgreSQL so that every account and ledger still balances afterwards.

Data engineering

ETL and data migration, source-to-target mapping, validation and reconciliation, and SQL performance tuning on PostgreSQL and SQL Server.

Data migration & engineering

  • Migrate core banking data for SACCOs and cooperatives from SQL Server, Microsoft Access, Excel and CSV into PostgreSQL. This covers customer/KYC, deposits, loans, shares, ledgers and general ledger.
  • Reverse-engineer undocumented legacy schemas and build the source-to-target data mapping for migration and reporting.
  • Run data validation, reconciliation and quality checks so balances and transactions match between source and target.
  • Write SQL queries, views and data-processing logic for financial problems such as interest, tax, penalties and chart of accounts.
  • Improve database performance through query tuning, indexing and execution-plan analysis.
  • Resolve production support issues on vouchers, deposit transactions and bulk SMS.

Infrastructure & operations

  • Administer Linux/Ubuntu and Windows (IIS) application servers, including service management with systemd, scheduled jobs with cron, log analysis and troubleshooting.
  • Deploy and maintain Docker-based environments, and configure Nginx as a reverse proxy for frontend, backend and API services.
  • Support Jenkins CI/CD workflows and Git branching and merging for deployments across dev, test, staging and production.
  • Handle PostgreSQL backup, restore, configuration, replication and availability monitoring.
  • Monitor service health, ports and connectivity, and work with development and QA teams to fix deployment failures.

Projects

PostgreSQL Streaming Replication

A primary/standby PostgreSQL setup on Linux for high availability and recovery.

  • Set up WAL-based streaming replication and initialised the standby with pg_basebackup.
  • Configured authentication, ports, network access and replication parameters.
  • Checked replication status and monitored sync between the two nodes.
  • PostgreSQL
  • WAL
  • pg_basebackup
  • Linux
  • Networking

Jenkins CI/CD Pipeline for a Containerised App

A pipeline that builds, ships and verifies a Docker application on every change.

  • Connected Git source control to Jenkins so builds run automatically.
  • Built Docker images and deployed containers to a Linux host as pipeline stages.
  • Added post-deployment health checks to confirm each release worked.
  • Jenkins
  • Docker
  • Git
  • Linux

Multi-Tier Application Deployment

A containerised FastAPI and PostgreSQL application behind an Nginx reverse proxy.

  • Containerised the app and database with Docker Compose, including networks and persistent storage.
  • Configured Nginx to route incoming traffic to the backend service.
  • Validated and troubleshot the deployment on Linux. Source code is versioned on GitHub.
  • Docker Compose
  • Nginx
  • FastAPI
  • PostgreSQL
