I’m an 𝐀𝐈 / 𝐏𝐲𝐭𝐡𝐨𝐧 and 𝐁𝐚𝐜𝐤𝐞𝐧𝐝 / 𝐍𝐨𝐝𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫 passionate about turning ideas into intelligent, data-driven products. My work bridges backend engineering with modern AI technologies: from 𝐋𝐌 integrations to 𝐚𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 and 𝐝𝐚𝐭𝐚 𝐩𝐢𝐩𝐞𝐥𝐢𝐧𝐞𝐬.
With experience in both 𝐏𝐲𝐭𝐡𝐨𝐧 and 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 / 𝐓𝐲𝐩𝐞𝐒𝐜𝐫𝐢𝐩𝐭, I build scalable APIs, connect machine learning models, and design reliable data flows for web and AI applications.

𝐂𝐨𝐫𝐞 𝐒𝐤𝐢𝐥𝐥𝐬 & 𝐓𝐨𝐨𝐥𝐬
• AI & LLM Integration: OpenAI API, LangChain, Perplexity, Firecrawl, Parallel, Octagon
• Automation & Workflows: n8n, Python scripts, REST / GraphQL APIs
• Backend Development: Node.js, Express, Next.js, FastAPI
• Databases & Vector Search: PostgreSQL, MySQL, Pinecone, Redis
• Data Handling & Logic: TypeScript, JavaScript, OOP, SOLID principles
• Architecture: Scalable, testable, event-driven and API-centric systems

𝐖𝐡𝐚𝐭 𝐈 𝐁𝐮𝐢𝐥𝐝
• Multi-agent systems with 𝐑𝐀𝐆 + 𝐯𝐞𝐜𝐭𝐨𝐫 𝐝𝐚𝐭𝐚𝐛𝐚𝐬𝐞𝐬
• Smart automation and data-extraction pipelines
• Scalable backends for SaaS and AI-driven platforms
• Integrations with third-party APIs and cloud services

I really enjoy building systems that combine AI intelligence with solid backend engineering.
