Hello there! I'm Vladyslav Waving Hand

Telegram GitHub Location: Germany Focus: Backend & AI

๐Ÿ’ซ Executive Summary & Engineering Philosophy

I am a Backend Engineer and AI Systems Developer with a passion for building robust, scalable architectures and autonomous agent ecosystems. My engineering focus lies at the intersection of high-concurrency backend services, LLM & vector search integrations, and resilient automation tools.

Whether designing a multi-agent social network simulator powered by vector databases, developing TLS-fingerprint-resistant automation engines, or authoring zero-cost OpenAI-compatible proxy wrappers in Go, I prioritize clean architecture, local-first data privacy, and production-ready reliability.

๐Ÿ”ฅ Core Engineering Pillars

  • ๐Ÿค– AI & Autonomous Multi-Agent Systems: Experienced in integrating LLMs (Google Gemini, OpenAI, DeepInfra, Ollama) with persistent semantic memory using Qdrant Vector Database and LangChain.
  • โšก High-Performance Backend & REST APIs: Architecting asynchronous services and microservices using Python (FastAPI, Django, Aiogram 3.x), Go, and Java.
  • ๐Ÿ›ก๏ธ API Resilience & Reverse-Engineering: Developing reliable scrapers and automation tools with TLS fingerprint resistance (curl-cffi), proxy rotation pools, and background task orchestration (APScheduler, Redis).
  • ๐Ÿณ Local-First DevOps & Containerization: End-to-end containerization using Docker & Docker Compose, database optimization (MySQL, PostgreSQL, Redis, Room), and clean multi-stage deployments.

๐Ÿš€ Flagship Open-Source Architecture Showcase

Below are comprehensive technical overviews of my core open-source projects. Each system is architected from scratch with custom algorithms, modern frameworks, and production-grade reliability.


๐ŸŒŠ BlackWave โ€” AI-Powered Social Network Simulator

A next-generation, local-first AI social network simulator where a single human user interacts with hundreds or millions of autonomous AI bots boasting long-term semantic memory and distinct personalities.

System Architecture Key Highlights & Value Proposition
โ€ข Social Network Backend: Built with Django & MySQL, handling user auth, interactive feeds, dynamic content moderation, and a comprehensive Admin Panel.
โ€ข AI & Memory Engine: Built with FastAPI & Qdrant Vector Database, orchestrating context-aware bot memory and personality traits.
โ€ข Multi-LLM Integration: Supports OpenAI, Google Gemini, Ollama, OpenRouter, and self-hosted models for hyper-realistic bot reactions.
โ€ข Autonomous Bot Ecosystem: Bots simulate real social dynamicsโ€”including fans, haters, neutral commenters, and humorous critics.
โ€ข Persistent Semantic Memory: Bots remember past posts and evolve their sentiment toward the user over time using vector embeddings.
โ€ข Audience Growth & Analytics: Simulates organic follower expansion, viral reach, and realistic engagement curves.
โ€ข 100% Private & Local-First: Complete containerization via Docker Compose ensuring total data control.

๐Ÿ” Keigen โ€” Intelligent Kleinanzeigen AI Search & Automation Bot

An enterprise-grade Telegram bot & automated search engine for Kleinanzeigen (Germany's largest classifieds platform), featuring GenAI query optimization, semantic intent evaluation, and real-time alerts.

Core Feature Technical Implementation & Capabilities
๐Ÿง  AI Query Expansion Uses Google GenAI (Gemini) & LangChain to automatically expand a single user prompt into optimized German keyword variations and synonyms to uncover hidden or non-standard listings.
๐Ÿ›ก๏ธ TLS Fingerprint Resistance Implemented with curl-cffi to precisely emulate native Android client traffic, seamlessly communicating with Kleinanzeigen mobile endpoints without triggering anti-bot blocks.
โฐ Smart Concurrent Parsers Background asynchronous scheduler (APScheduler 3.x + Redis) running recurring monitors with custom price boundaries, PLZ postal code radius filtering, and AI semantic intent filtering.
๐ŸŒ i18n Multi-Language Support Full internationalization supporting English (en), German (de), Russian (ru), Ukrainian (ukr), and Turkish (tur) with persistent user profiles.

โšก deepinfra-wrapper โ€” Self-Hosted OpenAI-Compatible Go Proxy

A lightweight, high-concurrency Go proxy server providing unlimited, self-hosted access to DeepInfra LLM models via standard OpenAI-compatible API endpoints.

  • Drop-in OpenAI Compatibility: Exposes fully compliant /v1/chat/completions and /v1/models REST endpoints with real-time SSE streaming support.
  • Auto-Rotating Proxy Engine: Automatically manages and refreshes a pool of public proxies to maintain high uptime and prevent request rate-limits.
  • Interactive API Documentation: Embedded Swagger UI for instant browser-based model testing and inspection.
  • Zero-Config Docker Deployment: Lightweight compiled binary containerized via GitHub Container Registry (ghcr.io).

๐Ÿ“ก Telezy โ€” Multi-Source Telegram Message Forwarder & AI Filter

A powerful automated message pipeline that forwards, modifies, and filters Telegram messages between chats using your personal accountโ€”no bot channel permissions required.

  • Advanced Content Processing: Whitelist/blacklist keyword rules, regex pattern replacements, link extraction, and media size/type filtering.
  • AI-Powered Summarization & Translation: Integrates LLM APIs (OpenAI/Claude) to automatically translate foreign streams, tag content, and generate scheduled 24-hour group digests.
  • Universal Multi-Platform Dispatch: Leverages Apprise to push processed notifications to Webhooks, Discord, Slack, Email, and SMS.

๐Ÿ“ฑ Todoshka โ€” High-Performance Android Task Manager

A sleek, responsive Android productivity application engineered with native Java, Room Persistence Library, and Google's Material Components.

  • Clean Architecture: Built on Android MVVM design patterns with high-performance local SQLite persistence via Room.
  • Rich Task Organization: Supports priority tags (Low/Medium/High), dynamic category management, instant full-text filtering, and personalized user profiles.
