Description

I build high-performance, scalable analytics solutions that turn complex data into clear, actionable business tools. If you need a developer who goes beyond simple visualizations to build a robust, production-grade backend, I can help.

I specialize in end-to-end BI development, ensuring that every dashboard is backed by clean data modeling and efficient ETL processes. My goal is to deliver tools that are not only intuitive for end-users but also easy to maintain and scale.

What I Bring to Your Project

I develop with a focus on stability and speed. My approach is rooted in technical best practices that prevent "technical debt" and ensure long-term performance:

Expert Qlik Sense Development: I specialize in building 3-tier QVD architectures that ensure data lineage and fast reload times. I use modular .qvs scripting to keep the backend organized, auditable, and professional.

ThoughtSpot Implementation: I build and optimize search-driven analytics environments, ensuring the underlying data models are perfectly tuned for live-query performance.

Advanced Data Modeling: I am an expert in Star Schema design. I don't just "load data"; I structure it to ensure your applications remain responsive even as your data volume grows.

B2B Ready: I operate through my own registered Bulgarian entity, making the B2B contracting process simple, VAT-compliant, and administrative-heavy for EU-based clients.

Common Deliverables

End-to-End Dashboard Development: Transforming raw requirements into fully functional Qlik or ThoughtSpot applications.

ETL Pipeline Optimization: Redesigning slow scripts and messy data layers into streamlined, modular processes.

Legacy Migrations: Moving data and logic from older systems into modern, high-performance BI platforms.

Custom Data Models: Designing the technical backbone (Star/Snowflake schemas) for complex enterprise reporting.
