i build Systems & Tools for Analysis, Prediction, Visualization, & Simulation.
i also design, code, and deploy complete distributed and (horizontally) scalable Machine Learning-based applications (e.g., anti-fraud filter, recommendation engine, monitoring/anomaly detectors), often in the service layer decoupled from the main app.
Techniques:
- Machine Learning
- decision tree (CART/C4.5) & random forest
- deep learning (multi-layer perceptron)
- support vector machine (SVM/SVR)
- kNN/kdtree
- probabilistic graphical models (eg, Bayesian Net, Markov Random Field)
- ***Dimension Reduction Techniques***
- spectral decomposition (PCA & kPCA, kLDA)
- Kohonen Map (self-organizing map)
- ***ETL pipelines***
- akka stream
- Apache Spark
- Kafka/Zookeeper
- ***Social Network Analysis & Visualization***
- using graph theoretic techniques for
- community detection
- identify members essential for network health/growth
- identify nascent sub-communities
- particular fluency in *NetworkX*, *GraphViz*
- ***Analysis & Modeling of Time Series***
- decomposition
- forecasting
- anomaly detection
- ***Optimization***
- combinatorial optimization
- csp
- ***Numerical Methods***
- matrix decomposition
- monte carlo techniques
- Gaussian quadrature,
- finite difference methods
- ***Persistence***
- redis
- postgres
- ***Geo-Spatial Data Modeling, Persistence, & Computation***
- postgis (storage, query, computation)
toolchain:
