Goio Streaming Library

https://github.com/Primetalk/goio/
An implementation of IO, Stream, and Fiber for Go inspired by cats and fs2. This library employs Go generics to implement functional programming concepts:
• IO (for managing computations)
• Stream (for infinite streams processing in a modular fashion)
• Fiber (parallel processing)

SynapseGrid

https://github.com/Primetalk/SynapseGrid/
Functional reactive programming framework for Scala. Allows fine-grained functional composition and processing of real-time data-streams. Has Akka-concurrency support and natural fine-grained concurrency.

SpeechPortal

A sophisticated framework for creating natural speech dialog applications. It is multichannel, parallel, and robust (24x7). Has built-in automatic speech recognition, speech synthesis, language parser and template engine, partial knowledge representation library. It stands apart for its intellectual dialog management framework and algorithms.

Scala Concurrency Course

A course that I'm teaching on concurrency on the JVM platform, including classic tools (like threads, synchronization primitives, non-blocking techniques), Akka and Akka Streams frameworks, Cats IO and FS2 frameworks.

Slack Chatbot

I developed a Slack chatbot application that provides access for team orchestration with the back end written in Golang using an AWS cloud stack and Terraform. It is based on the book "Adaptive: Scaling Empathy and Trust to Create Workplace Nirvana" available at https://www.amazon.com/Adaptive-Scaling-Empathy-Workplace-Nirvana-ebook/dp/B07WSGD18D
