David Baque

Three years building software, combining freelance projects that remain in production with professional experience building scalable, distributed systems as part of engineering teams. I specialise in clean architecture and microservices with Go and TypeScript, keeping business logic decoupled from infrastructure details.

Experience

02/2025 — present

Backend / Microservices Developer

FarmaConnect / Keonex

I build backend services and microservices for the FarmaConnect/Keonex ecosystem, connecting pharmacy ERP integrations, business logic and ESL electronic shelf label systems.
I designed and implemented a Golang system from scratch to orchestrate thousands of ESL labels and antennas, adding telemetry, metrics and full traceability for image changes.
I defined entities, use cases and documented API contracts, keeping the domain decoupled from communication and rendering infrastructure.
I implemented a Docker-based pre-production environment with automated GitHub Actions deployments, reducing production risk and improving service stability.

01/2024 — 06/2024

Backend Developer

Neby (University)

I coordinated the technical backend foundation for a team of 8 people, defining structure, endpoints and the data model.
I developed the backend in C++ and integrated PostgreSQL as the persistence layer.
I implemented unit tests with Google Test and configured Docker to provide a reproducible development environment.

08/2023 — 10/2023

Full Stack Developer

Take Order (Freelance)

I developed a full stack restaurant order management application, covering frontend, backend, database and deployment.
I designed the backend with Node.js, TypeScript and a PostgreSQL database for orders, payments, products and customers.
I implemented real-time communication with WebSockets between waiters and kitchen staff.
Due to client data-protection requirements, I deployed a private server inside their local network so information never left their premises.
