Multivariate Time Series and Graphs classification

Julia Python Graph Neural Networks ...

  • Classification as such
  • Very complex data gathering and preprocessing in various formats
  • Datasets creation
  • Nodes and graph features creation
  • Embedded models in the place of Kernels
  • Meta models
  • Layers execution in parallel
  • Multivariate time series
  • Non-sequential neuralnetworks
  • Reading scientific publications from arxiv. org
  • Questioning Copilot and Gemini to discover new concepts of neural networksprogramming.
  • Investigating these new concepts.
  • Creating various neural network architectures and various graph topologies.
  • Training, validating, fighting to improve accuracy.
  • Custom training cycle. 
  • Hyper parameters tuning. 
  • Genetic algorithms not yethere Custom Loss functions. 
  • Residuals, attention, boosting, and other tricks.
  • Flux.jl layers customization. 
  • Float64 everywhere.
  • Graphs data augmentation.
  • Fixed one GraphNeuralNetworks.jl bug here.
  • All this experience can be used in another MLOps role
  • I could be extremely useful in parallel processes programming for neuralnetworks training and inference.
  • Plus, strong Cloud and Kubernetes backends programming skills.

Ansible Playbook to create Kubernetes cluster

Backend Developer and DevOps Kotlin Kubernetes Spring Boot ...
Backend Developer and DevOps

  • Ansible Playbook to create Kubernetes cluster on Fedora Linux and fill it withKafka and other required components.
  • Spring Boot and Kotlin based programming for Kafka.
  • RSA signature check for HTTP requests.
  • Test Runner for Bare Metal Kubernetes development. 
  • That is needed to launch Integration and e2e tests inside of the Kubernetes.
  • Advanced testing of events based backends is very tough topic.
  • No place for just unit tests folks here.

Node.js NestJS and mongodb learning activity

  • Evaluating Node.js NestJS framework by doing some coding in it.
  • It usuallyends with the template to kick start the projects with particular technology set.
  • From all Node.js frameworks I used in 3+ years, NestJS seems to be the best.
  • Probably, because I spent 9 years with Java and Kotlin 
  • It is Java worldclone, noticeably.
  • Golang is different, because it is functional language. 
  • Golang wins them all.
  • Probably Rust even more.
  • If you would pay me, I would create Rust web services template too.

Go API style web service

Android Developer + DevOps Mobile Apps Servers IoT ...
Android Developer + DevOps

  • Go API style web service which allows storing Players high scores into the Leaderboard and query them by several filters (top, paging, players aroundme, time domains)
  • Go micro service development to query mobile apps logs from the Couchbase.
  • Android app's Timber is storing log messages into the Couchbase Lite for offline storage, and synchronizing them with the server when possible.
  • Julia language in IoT scenarios - Smart Home, Smart City, Skynet (mentionedAndroid app exports photos dataset for image classification neural networkstraining here)
  • Android App to prepare pictures for Smart Homes Vision neural networkstraining and upload to the Google Drive (Kotlin, Coroutines, Flow, CameraX, MVP, Work Manager)
  • WebSockets server and client in Go language
  • Because of the speech recognition and synthesis had to start coding in Pythonagain.
  • Is it honestly so superior programming language? 
  • Mozilla DeepSpeech and TTS for go based IoT systems
  • Go language for micro services, IoT, and Servers (inside Kubernetes, ofcourse)
