1) Implemented various data structures using C++.
2) Implemented various cryptographic primitives and algorithms using C++ and Golang.
3) Developed desktop applications using Qt, QML, and C++.
4) Created and tested smart contracts in Solidity and JavaScript.
5) Conducted unit testing in C++, Golang, and Python.
6) Developed a decentralized application using Solidity, Vue, and Quasar.
7) Created interactive chats using client-server architecture with proxy servers based on C++ and JavaScript.
8) Modified Bitcoin Core source code as a fork in C++ to introduce innovative methods for ensuring private data anchoring to time based on ECDSA and Schnorr digital signatures.
9) Developed a decentralized voting system based on the Aleo blockchain.
10) Built applications using React, Python (FastAPI), and Docker.
11) Implemented various Computer Vision and Natural Language Processing tasks using classical and deep machine learning algorithms with Python, scikit-learn, and TensorFlow.
Current role.
I have four months of commercial development experience as an Intern C++ Developer at Apriorit and six months as an Intern Blockchain Developer at Distributed Lab. Currently, I am not employed commercially. Recently, I participated in a team-based charity project aimed at creating a comprehensive platform for animal shelters.
In the recent charity project, I was responsible for:
1) Front-End (React).
2) Back-End (Python and FastAPI).
3) DevOps (Docker, Nginx, and Bash).
4) Platform security (password hashing with SHA-256 and "salt", personal data encryption with AES, JWT for API protection, CORS, frontend redirection, etc.)
5) Hosting and domain setup (Namecheap, Heroku, and DigitalOcean).
6) Integration of AI into the application (dog and cat image recognition using a transformer neural network from Hugging Face).
I aspire to evolve as a Machine Learning Engineer.
2) Developed a custom smart contract for decentralized voting and deployed it on the Ethereum network.
3) Implemented an innovative method for ensuring private data anchoring to time in Bitcoin by embedding data into ECDSA and Schnorr digital signatures. The project was realized as a modified fork.
4) Developed a decentralized voting system based on zero-knowledge proofs and the Aleo blockchain. Utilized React, Python, FastAPI, Docker, and the Leo language for creating the Aleo program.
5) Effectively applied convolutional neural networks in natural language processing tasks.
For me, the principle of "company for people" is paramount, rather than "people for the company". I believe in fostering a friendly and open atmosphere within the company, where individuals feel comfortable approaching others for advice or assistance without hesitation. Collaboration and support are key to success, ensuring that no one feels isolated.
