Oleksii M.

I’m a software engineer and founder with deep experience in mobile, backend, DevOps, AI, and embedded systems. I build products from scratch, optimize performance, and explore cutting-edge technologies while keeping delivery practical and reliable. 💼 Business & Leadership As the owner of a development studio and co-founder of startups, I gained solid experience in setting up product development from scratch. I understand business processes and know how to design workflows that ensure successful delivery. 📱 Mobile Development Started iOS development in 2011. Built 20+ apps and 8 open-source libraries with C/C++/ObjC/Swift. In 2018, expanded into Android (4 apps in Kotlin). Since 2021, focused on Flutter: 6 apps and 6 open-source libraries, mainly in blockchain and cryptography. Also worked with Flutter FFI, Android NDK, ARM64 assembly, and Metal for performance-critical integrations. I have experience with Flutter FFI, Android NDK, ARM64 low-level optimization, and Metal, which allows me to integrate performance-critical native code when high efficiency is required. 🖥️ Backend & DevOps Began backend in 2013 with Python (Flask, MongoDB, RabbitMQ). Since 2018, focused on Golang: 9 projects (monoliths & microservices) and 10+ open-source libraries. Deployment usually with Docker (Terraform, Compose, Kubernetes, SaaS). Also experimented with Elixir (WS servers), Rust (high-performance services), Node.js (Socket.IO), and Python (ML model deployment). Pragmatic in tool choice, aiming for reliability and performance. 🤖 Artificial Intelligence Started AI in 2019 by training an audio-processing network in TensorFlow, working on dataset building, bias, and overfitting. Wrote a cross-platform C library for on-device inference and lightweight training, which deepened understanding of gradient descent and NN math. Since 2024, actively using OpenAI and other LLM APIs in real-world projects. 📡 IoT In 2020, ported Azure IoT SDK to watchOS. In 2024, explored IoT projects: a BLE-controlled smart socket and a custom ESP32 drone with flight controller, IMU drivers, and ESP-NOW. Gained ESP32 and embedded programming experience. ⛓️ Blockchain Since 2025 dive into web3 infrastructure within TON, Aptos. Writing custom smart contracts on TON, understanding TVM, debugging smart contracts. Using high load wallet to write TONs of Txs on TON :) 📚 Academic & Exploration Studied OS internals and hardware design, including building a single-cycle CPU in Verilog, which clarified OS and VM concepts. Explored cryptography (post-quantum), quantum computing, and Web3 VMs. Currently exploring hardware for secure data encryption (message encrypter / cold wallet), combining crypto, OS, and hardware knowledge. This background improves debugging, performance analysis, and system design. This broad technical foundation helps me debug complex systems, analyze performance bottlenecks, and design robust architectures that scale.
