Architectural Insights & Engineering Notes
Written by Dhruvil Thummar (Co-founder & CTO at The Intelliverse). Practical engineering deep dives into machine learning algorithms, production MERN microservices, database tuning, and technical leadership.
Architecting High-Throughput 3-Tier Microservices: Lessons from The Intelliverse
How we decoupled monolithic services into resilient, low-latency microservices with Redis caching, circuit breakers, and sub-50ms database queries.
CatBoost vs. XGBoost in Financial & Stock Price Prediction: An Empirical Benchmark
In-depth empirical comparison of CatBoost vs XGBoost on non-stationary market time-series, categorical feature encoding, and out-of-fold generalization.
Mastering Exploratory Data Analysis (EDA) for Production Machine Learning
A structured, production-ready framework to uncover multicollinearity, handle missingness bias, and engineer robust features before fitting machine learning models.
Scaling WebSockets for 10,000+ Concurrent Real-Time Clients in Next.js 16
Implementing Redis Pub/Sub backplanes with connection pooling and heartbeat health checks to scale real-time event broadcasting reliably.
Sub-50ms MongoDB Query Optimization: Indexing Strategies & Aggregation Pipelines
Real-world indexing strategies (compound, sparse, text), explain plan analysis, and avoiding costly in-memory sorts in high-volume databases.
The Modern CTO Playbook: Transitioning from Code Contributor to Engineering Leader
How to establish engineering standards, manage technical debt, foster high-velocity developer culture, and align product vision with technical execution.
