Full-cycle IoT product development from schematic to production.\n\n**Connect** — Cloud integrations, Home Assistant, Node-RED automation, AI layers where they genuinely add value (not as a buzzword).\n\n**Secure** — Firmware analysis, IoT infrastructure pentesting, AI security audits. I find vulnerabilities before someone else does.\n\n---\n\n## 🏆 Commercial Work\n\n### 🌿 Lephrone H01 — Smart Aroma Diffuser (US Client)\nIoT product built from scratch: ESP32-S3 firmware, Flutter mobile app, cloud backend with OTA updates. Full technical documentation including threat modeling and security architecture.\n\n`ESP32-S3` `ESP-IDF` `FreeRTOS` `Flutter` `FastAPI` `MQTT` `AWS IoT`\n\n### 🔐 Backend Pentest Reports (×2 commercial projects)\nFull-cycle security assessments for real production systems. 10+ documents of structured findings — vulnerabilities, severity ratings, remediation plans. Critical API and infrastructure issues identified and closed before exploitation.\n\n`Burp Suite` `nmap` `Wireshark` `OWASP` `REST API security`\n\n### 🧠 Enterprise RAG System (Logistics)\nKnowledge base bot for auto repair shop: vector search over 1C database and unstructured docs. 3x faster issue resolution for technicians.\n\n`Python` `ChromaDB` `LangChain` `FastAPI` `Telegram Bot API`\n\n---\n\n## 🛠 Tech Stack\n\n**Embedded \u0026 Hardware**\nESP32 · ESP-IDF · FreeRTOS · MicroPython · KiCad · Ghidra\n\n**Backend \u0026 Infrastructure**\nPython · FastAPI · MQTT (Mosquitto) · Docker · PostgreSQL · Redis · Ubuntu Server\n\n**Mobile**\nFlutter · Dart\n\n**Security**\nBurp Suite · Wireshark · nmap · Ghidra · Firmware analysis · OWASP IoT Top 10 · Prompt injection · AI red-teaming\n\n**Automation \u0026 Monitoring**\nHome Assistant · Node-RED · InfluxDB · Grafana · Tuya IoT\n\n**AI \u0026 LLM**\nOpenAI · Claude · LangChain · RAG · Vector search · LLM-accelerated development\n\n---\n\n## 💡 My Methodology\n\nI use LLMs as acceleration — not as replacement for thinking. For firmware, security research, and system architecture, there's no shortcut: the work requires genuine reasoning. LLMs handle the scaffolding; I handle the decisions that matter.\n\nThis is why I moved into IoT security specifically: it's one of the few domains where you can't fake competence. Either the system holds or it doesn't.\n\n---\n\n## 📝 Writing \u0026 Research\n\nI publish on connected systems, security, and the technology transition we're living through:\n\n- **Habr** — Technical deep-dives in Russian (photo archive classification system, LLM-driven development methodology, IoT architecture)\n- **CyberCore (Telegram)** — `@CoreEuler` — Philosophical and technical takes on how the world is becoming computational\n\nI believe the gap between people who understand connected systems and people who live inside them is the defining security vulnerability of this decade. I write to close that gap.\n\n---\n\n## 📊 By the Numbers\n\n- 🔌 1 commercial IoT product shipped (US client, full cycle)\n- 🔐 2 commercial pentest engagements with full documentation\n- 📄 10+ security assessment documents written\n- ⚡ LLM-accelerated development: prototypes in days, not weeks\n- 💼 Average project value: $800–3000\n\n---\n\n## 🎯 Current Focus\n\nBuilding expertise at the intersection of:\n- **IoT Security** — firmware analysis, protocol security, infrastructure hardening\n- **AI Security** — LLM integration audits, prompt injection, red-teaming AI-powered products\n- **Connected Systems Architecture** — designing systems that are both functional and defensible from day one\n\n---\n\n## 🤝 Open to\n\n- IoT product development (firmware → backend → app)\n- Security audits of connected systems and IoT infrastructure\n- AI integration security reviews\n- Technical writing and research collaboration\n\n---\n\n## 🌱 Background\n\nSelf-taught developer. Former logistics analyst. Built my own LLM-accelerated development methodology before \"vibe coding\" became a term — documented it on GitHub and Habr. Transitioned from AI/automation freelancing into connected systems and security because that's where the work still requires thinking.\n\nBased in Russia. Working with global clients.\n\n**Philosophy:** The world is accelerating faster than people can adapt. The gap between those who understand connected systems and those who don't is growing — and that gap is dangerous. I build things that work, find where they break, and write about what I learn.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcore-euler%2Fokoloboga","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcore-euler%2Fokoloboga","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcore-euler%2Fokoloboga/lists"}
