Frequently asked questions

How quickly can you start working on my project?

Typically, I can kick off new projects within 1-2 weeks after contract finalization. For urgent or high-priority situations, I keep some flexibility in my schedule—just let me know your timeline during our initial consultation, and I'll do my best to accommodate.

Do you require a minimum project size or commitment?

While I'm flexible on project sizes, engagements of around 20 hours or more typically allow for deeper analysis, tailored solutions, and measurable impact. However, we can certainly start with a smaller pilot project to ensure mutual fit and immediate value.

What industries do you have experience in?

I've successfully delivered impactful data projects within fintech, crypto, manufacturing, and government sectors. My expertise particularly shines in projects involving analytics engineering, automated data pipelines, real-time anomaly detection, and process optimization.

How do you handle data security and confidentiality?

Data security is at the heart of my work. I sign comprehensive NDAs before beginning any engagement, utilize enterprise-grade encryption, and strictly follow best practices aligned with SOC2 and ISO27001 standards. Additionally, I'm experienced working within existing security frameworks and compliance requirements.

What's your pricing structure?

I offer project-based pricing tailored to scope, complexity, and delivered value, ensuring clear ROI rather than purely hourly billing. For ongoing engagements, I provide retainer packages designed to offer continuous support and optimization. Let's discuss your specific requirements during our consultation to identify the best model for your business.

How do you communicate progress and results?

Clear and consistent communication is key—I provide weekly updates and hold regular check-in meetings. You'll receive comprehensive documentation of all findings and recommendations, complemented by interactive, self-service dashboards.
