Who I am and How I work

Alexey Belochenko Profile

Alexey Belochenko

Systems & Data Engineer

CET / UTC+1 (US/EU overlap)
Fractional Lead, R&D Consultant

I model dynamic systems, build resilient platforms, and keep teams honest about failure modes. I don’t build in a vacuum: I anchor scientific rigor in practical engineering to ensure theory withstands the friction of real-world production. My mandate: stabilize the noise, enforce observability, and ship the smallest proven step forward.

Strategic Architecture

High-level system modeling, technical due diligence, and no-nonsense roadmaps.

High-Performance Engineering

Production-grade pipelines, vectorization, and merciless incident drills.

Scientific R&D

De-risking complex domains through mathematical modeling and rapid prototyping.

Career Snapshot

  • 7+ years engineering mission-critical systems, bridging the gap between Scientific Computing and Enterprise Infrastructure.
  • Founder experience leading R&D for autonomous aerial systems (Elliscope), integrating hardware sensors with Python telemetry.
  • Optimized wind energy simulation pipelines on GPU clusters (GE Vernova), achieving 5-10x acceleration in task execution.
  • Architected Airflow data pipelines for clinical trials (Trialing Health), slashing processing time by 67% and enabling real-time analytics.
  • Orchestrated cloud migrations and disaster recovery plans for Fintech clients, reducing operational costs by up to 25%.
  • Mentored 150+ engineers and introduced scientific rigor to development processes, transforming theoretical teams into production units.

My Engineering Discipline

Calculated Risk

Innovation requires control. I explore new domains through rigorous experimentation, ensuring client stability while pushing technical boundaries.

Data Over Intuition

Every hypothesis is validated using applied mathematics and objective performance metrics. No guessing - only proofs.

Future-Proof Architecture

Solutions are designed for hyper-scale from day one. I build systems that survive real-world load and support tomorrow's growth.

Performance by Design

Speed is a feature. I deliver measurable breakthroughs through algorithmic optimization and custom vectorization libraries.

Technical Debt Elimination

I systematically dismantle legacy inefficiencies. Clean code and simplified workflows unlock resources for rapid innovation.

Force Multiplication

I don't just write code; I elevate teams. Having trained 150+ developers, I enforce standards that ensure collective competence.
