About Martin

🤝 Free 30-Minute Strategy Call:

I offer a complimentary initial 30-minute consultation to understand your core challenges, outline a strategic action plan, and provide a transparent timeline and budget estimate - zero commitment.


Are your cloud compute costs out of control? Are legacy code and slow data pipelines bottlenecking your product's growth? I architect and fully implement high-performance, globally scalable systems that drive business ROI.

As a Technical Founder I specialize in Performance-First Engineering. I help scale-ups and global enterprises build robust architectures from scratch or rescue inefficient systems, ensuring every technical decision aligns with cost-reduction and scalability goals.

How I drive impact:

Extreme Optimization & Client-Side Compute: Successfully compiled heavy legacy C/C++ simulation engines (EPANET/SWMM) into WebAssembly for native browser execution. This enabled zero-latency analytics and completely eliminated backend compute overhead for a complex SaaS platform.

Enterprise Data & FinOps: Architected a strategic migration to Microsoft Fabric for a global IoT platform. Leveraged Direct Lake mode to resolve severe Power BI bottlenecks, delivering instant data reporting and slashing cloud ingestion costs.

Open-Source Impact: Contributions to cleanlab (11k+ stars), heavily optimizing algorithmic efficiency for ML workflows used by developers worldwide.

Pricing & Engagement:

While available for daily/hourly consulting, I highly prefer and offer Fixed-Price / Value-Based Project pricing so we align on deliverables and ROI, not hours worked.

Technical Arsenal:

Core: Python (Expert), SQL, JS/TS, WebAssembly, Optimization.
Data & Cloud: AWS, Azure, GCP, Fabric, Snowflake, Serverless IoT ETLs.
AI & ML
Web: FastAPI, Svelte, Docker, CI/CD.

Fluent in English (C1) and highly accustomed to working async with US and global teams.
