Your AI prototype works in a notebook. Making it survive production (async queues, retry logic, latency budgets, real users), - that's where I come in. Backend: - Production-ready APIs (FastAPI, Django, Flask) - Database design and performance tuning (PostgreSQL, Supabase) - Secure authentication, roles, and permissions - Refactoring unstable or experimental AI-heavy codebase - Dockerized deployments and cloud readiness AI and LLM systems - LLM-powered automation - Custom AI agents and assistants (LangChain) - Optimizing AI pipelines for latency, reliability, and cost - Hardening AI features for production use Automation and AI Workflows - AI-driven workflow orchestration (human-in-the-loop, fallback logic) - End-to-end automation using n8n, Zapier, Make - Connecting AI systems to internal services and third-party APIs My tech stack: Claude Code (yes, I use it a lot to save time and be productive!), Python, FastAPI, Django, Flask, PostgreSQL, Supabase, Docker, Git, LangChain, Kubernetes, GCP, Azure. My recent production projects: • AI Support Ticket Processing System Built an end-to-end backend for an AI system that automates ticket routing and resolution. Focused on latency optimization and building reliable fallback mechanisms so the LLM doesn't hallucinate critical client data. (Tech: FastAPI, LLMs, PostgreSQL) • Back-end developer at a Czech fintech company (Fair Play). Developed and shipped critical features in a high-stakes environment on GCP/Kubernetes. Improved test coverage from 60% to 92%, reduced deployment failures by 80%, and optimized services to handle peak loads with zero downtime. Result: Faster feature releases and enhanced system reliability in a compliance-heavy industry. • Part-time Python back-end developer in a foreign company Glasswall Solutions. Worked on unit tests, bug fixes and project features. We were using Azure as our cloud service provider. Dealt with Paramiko Python library. • Custom CRM development at Hyperbach company This is an internal CRM / HRM platform. It includes 3rd-party API integrations, REST API development, and DB management. It is being written from scratch in Python, Flask, Alembic, PostgreSQL, Docker, Vue.js. Delivered a robust internal tool that automated HR processes, saving the team 20+ hours/week in manual work and scaling to support 500+ users seamlessly. • Custom FastAPI backend for SaaS business I designed and implemented a production-grade FastAPI backend for a mid-size internal SaaS tool used by a distributed team. The project required a clean, scalable architecture capable of supporting multiple user roles, growing feature sets, and third-party integrations. The backend was built using an asynchronous, modular structure, allowing the system to handle high loads and remain maintainable as new features are added over time. If you have an AI prototype that needs to become a real product or you need a solid backend built from scratch, let's talk.

I am a Senior Python Engineer with 4+ years of experience designing, developing, and scaling high-performance backend systems, APIs, and data pipelines for startups and enterprise clients.

What I Deliver Robust backend systems built with Django, Flask, and FastAPI High-performance REST & async APIs with secure authentication Scalable data pipelines (ETL/ELT) and automation solutions Cloud-ready deployments on AWS with best practices Clean, well-documented, and testable code Technical Expertise Backend: Django, FastAPI, Flask, REST APIs, Async Processing Data Engineering: Web scraping, ETL pipelines, data validation, automation Databases: PostgreSQL, MySQL, MongoDB, Redis Cloud & DevOps: AWS (EC2, S3, RDS, Lambda), Docker, CI/CD Scraping & Automation: Scrapy, Selenium, BeautifulSoup Tools: Git, Linux, Celery, Message Queues Why Clients Choose Me Senior-level ownership and accountability Clear communication and realistic delivery timelines Strong focus on scalability, security, and performance Long-term mindset—not just task completion If you need a dependable engineer who understands both code and business impact, I’d be happy to discuss your project.

I build production-ready AI and Python backend systems for SaaS, healthcare, fintech, and data-heavy products, including LLM applications, RAG pipelines, FastAPI backends, AI copilots, voice AI workflows, and secure API integrations. I am a Python AI Backend Engineer with 13,000+ Upwork hours, $300K+ earned, 100% Job Success, and Top Rated Plus status. My work is focused on building AI systems that are not just impressive in a demo, but stable, secure, and useful in real production environments. My core work includes: - LLM applications using OpenAI, Claude, Gemini, LangChain, LangGraph, and LlamaIndex - RAG systems using vector databases like Pinecone, pgvector, Qdrant, or Weaviate - Python backend development with FastAPI, Django, Flask, PostgreSQL, and AWS - AI copilots, chatbots, internal assistants, and workflow automation tools - Voice AI systems using Whisper, Twilio, speech-to-text, and real-time backend workflows - Healthcare AI workflows, clinical assistants, medical data handling, EMR/EHR-related integrations - FinTech & data-heavy SaaS platforms involving analytics, reporting, automation, and secure APIs - Authentication, RBAC, logging, background jobs, API architecture, and scalable cloud deployment A lot of AI projects fail because the backend, data flow, permissions, evaluation logic, and integrations are not designed properly. I focus on those parts early so the system can grow without needing to be rebuilt later. I am a good fit if you need someone who can: 1) Turn an AI idea into a practical technical architecture 2) Build a secure Python/FastAPI backend for your AI or SaaS product 3) Design RAG pipelines around real business, medical, or financial data 4) Integrate AI into an existing healthcare, fintech, or SaaS platform 5) Improve an unstable AI prototype and make it production-ready 6) Work directly with your team and communicate clearly without overcomplicating things If you’re building an AI product and want it done properly, I’d be happy to review your requirements and suggest the best technical direction.
