Эдуард is ready for their next project!

I build independent engineering projects, prototypes, and MVPs at the intersection of AI automation, backend systems, and product architecture.
I turn complex ideas into clear modules, roles, states, API contracts, and user flows. My work covers:
• AI orchestration: LLM integrations, agents, task pipelines, state machines, and context management
• Backend and integrations: FastAPI, REST APIs, OpenAPI/Swagger, webhooks, SQLite, Telegram systems, and data pipelines
• Product systems: operational dashboards, role-based flows, service catalogs, and UX/UI architecture
• Technical infrastructure: Android/ADB workflows, local runtimes, PowerShell automation, and reproducible launchers
• Web security: application mapping, REST/GraphQL discovery, and safe vulnerability validation
Core stack: Python, FastAPI, asyncio, Telethon, httpx, Node.js, OpenAI API, REST/OpenAPI, SQLite, Android SDK, JDK 17, ADB, and PowerShell 5.1.
I work from architecture through implementation, with maintainable interfaces, documented decisions, and practical delivery.
