Tech founders and CTOs hire me, a results-driven AI Engineer and Backend Developer , when they need to transition an unpredictable AI prototype into a secure, scalable, production-grade system. Most AI projects stall because developers build fragile prompt wrappers that break under real-world traffic. As a senior AI Engineer, I specialize in building robust Python backends, autonomous multi-agent architectures, and deterministic software engines designed to run reliably at scale. My AI systems are engineered for production, not demos. Over the past eight years, I have engineered and deployed technical systems that translate directly into business value. As a Backend Developer and AI Engineer, I designed a cross-industry MVP in 2021 for the healthcare, real estate, and fintech sectors that successfully scaled into a commercial B2B SaaS platform currently generating over $7M in recurring ROI per annum, proof that strong Python-driven architecture and disciplined AI engineering deliver real outcomes. 𝗪𝗵𝗮𝘁 𝗬𝗼𝘂 𝗚𝗲𝘁 𝗪𝗵𝗲𝗻 𝗪𝗲 𝗪𝗼𝗿𝗸 𝗧𝗼𝗴𝗲𝘁𝗵𝗲𝗿 • Production AI & RAG Pipelines: As a dedicated AI Engineer, I implement advanced Retrieval-Augmented Generation (RAG) pipelines using custom chunking strategies, token optimization, prompt caching, and hybrid semantic search via OpenAI and Claude APIs. Every RAG system I build is optimized for accuracy, speed, and cost efficiency. • Autonomous Multi-Agent Systems: Multi-step orchestration workflows built with LangChain, AutoGen, and MCP (Model Context Protocol) to handle continuous background monitoring and complex data execution, core capabilities every modern Backend Developer specializing in AI must master. • High-Performance Backend Architecture: Fast, asynchronous REST APIs engineered with Python and FastAPI, keeping your probabilistic AI outputs strictly separated from exact financial or relational database logic. Clean Python architecture is non-negotiable at scale. • Enterprise Infrastructure & MLOps: Containerized deployments using Docker, automated Infrastructure-as-Code (IaC) via Terraform, and continuous integration pipelines with GitHub Actions across AWS and Azure AI Foundry, built to support enterprise SaaS operations end to end. • Full SaaS Core Frameworks: Secure relational database modeling (PostgreSQL, Supabase, SQL Server), OAuth/JWT authentication (Clerk, NextAuth), and multi-tenant subscription mechanics using Stripe, the complete SaaS stack, fully production-hardened. 𝗪𝗵𝘆 𝗜 𝗔𝗺 𝘁𝗵𝗲 𝗥𝗶𝗴𝗵𝘁 𝗙𝗶𝘁 𝗳𝗼𝗿 𝗬𝗼𝘂𝗿 𝗣𝗿𝗼𝗷𝗲𝗰𝘁 • Trench-Tested Technical Ownership: Having spent over eight years working between business clients and core development teams as both AI Engineer and Backend Developer, I don't need hand-holding. I design the database schemas, analyze response latencies, and minimize api token burn rates out of the box. • Security & Compliance Frameworks: I understand how to handle AI data pipelines under strict operational guardrails, including HIPAA compliance and PHI data protection for healthcare SaaS software, and SOC2 readiness for fintech operations. • Clean, Enterprise-Ready Deliverables: Every Python-engineered system I deploy features comprehensive automated testing (Unit/E2E), explicit error trapping, and structured operational runbooks so your internal engineering team can scale it smoothly. • Full-Stack Fluency: While my core domain is AI backend engineering, optimization, and MLOps, my proficiency as a Backend Developer with React and Next.js ensures absolute alignment across your front-end asset publishing and user journey layouts , critical for polished SaaS products. Whether your platform requires deep document intelligence with RAG and OCR pipelines, local open-source model serving via vLLM and llama.cpp, or deep third-party integrations with travel GDS, WhatsApp Business, or Meta/Google Ads APIs, as your trusted Backend Developer and senior AI Engineer, I build it to last in Python.
