AI/ML & Cloud Solutions Engineer
Sergey Molkov
About me
Hi! I'm Sergey Molkov.I'm an aspiring AI/ML Engineer with a strong foundation in cloud infrastructure (Microsoft Azure, AWS).My focus is on applied machine learning — data preprocessing, feature selection, classification, and ensemble modelling — to build intelligent, data-driven systems. I complement this with hands-on cloud engineering experience: designing and maintaining cloud architectures, containerization (Docker, Kubernetes/AKS/EKS), and secure, highly available infrastructure, guided by Azure and AWS Well-Architected Framework principles.Before moving into tech, I spent over a decade leading operations for a national broadcasting company, sharpening my problem-solving, leadership, and cross-functional collaboration skills — strengths I now bring to data and engineering teams.
My skills
- Data Science & ML: Python (Pandas, NumPy, Scikit-learn, LightGBM, Matplotlib)
- Programming Languages: Python, Bash
- Cloud Technology: Azure, AWS
- Containers and Container Orchestration: Docker, Kubernetes
- Cloud Application Architecture: Microservices, Serverless, CI/CD
- Foundational IT Knowledge: Windows Server, Linux
- Networking: TCP/IP, DNS, VPN, Firewall
- Database Languages: PostgreSQL, SQL
Hands-on projects
1. Production-grade 3-Tier Architecture on Microsoft Azure
A secure, scalable 3-tier cloud architecture on Azure, including Azure App Service frontend, private AKS backend with Internal Ingress, and Azure SQL via Private Endpoint, all routed through Azure Front Door Premium with end-to-end Private Link and strict network isolation.2. Secure Enterprise Environment in Azure
Azure AD with MFA and Conditional Access, Key Vault for secrets management, disk and database encryption, Azure Defender + Sentinel for threat detection, Network Security Groups, Azure Firewall, and Azure Policy for enforced compliance.3. Classic ML
Applied ML and data science: preprocessing pipelines (SimpleImputer, IterativeImputer), COVID-19 exploratory analysis, real estate price prediction (Linear Regression), an automated multi-method feature selection tool (Pearson, Chi-Square, RFE, Lasso, Random Forest, LightGBM), Random Forest tuning with RandomizedSearchCV, customer classification with a Voting Ensemble, and a Selenium-based Yelp review scraper.
4. Computer Vision & NLP
Text, image, video, and audio pipelines: a PDF-to-speech audiobook generator with typography-aware text cleaning (PyPDF2, pyttsx3), extractive summarization benchmarking four algorithms (TextRank, LexRank, Luhn, LSA), foreground extraction comparing global, Otsu, and adaptive thresholding, and two real-time OpenCV webcam applications — a Haar cascade cartoon face filter and a background-subtraction intrusion detector.
