Most businesses do not need more software. They need n8n, Make, and AI agents that connect their existing tools, data, and processes together. I help companies eliminate manual work, automate operations, and deploy RAG-powered, agentic AI systems built in Python that save time, reduce costs, and let teams scale without adding headcount. Over the past 12+ years, I have delivered 160+ projects across SaaS, Healthcare, Real Estate, eCommerce, Hospitality, Finance, and Service-based businesses. 🏆 Top Rated Plus ⭐ 100% Job Success Score ⭐ 99% 5-Star Reviews 🚀 160+ Projects Delivered 𝗪𝗛𝗔𝗧 𝗜 𝗗𝗢 AI Agents & Agentic Workflows - OpenAI, Claude, Gemini - Multi-agent systems - Claude Code implementation - MCP integrations - Autonomous business workflows - Research, support, and operations agents 𝐑𝐀𝐆 & 𝐊𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 - Vector databases - Document processing pipelines - Internal knowledge assistants -AI-powered search systems - Company knowledge bases - Long-term memory architectures 𝐖𝐨𝐫𝐤𝐟𝐥𝐨𝐰 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 - n8n - Make - Zapier - Lindy.ai -Lovable - Supabase I build automation systems with proper error handling, retry logic, monitoring, logging, and documentation so they continue working long after deployment.

My approach is simple: -First understand the business process. -Then identify the bottlenecks. -Then automate the right parts. -Not the other way around. If you have a repetitive process, disconnected systems, or an AI idea you want turned into a working solution, send me a message with a brief overview of your workflow. I will tell you what can be automated, what cannot, how long it will take, and the best way to build it.

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'm a hands-on Software Architect & AI-Enabled Systems Engineer with 20+ years of experience building scalable web platforms, SaaS products, mobile apps, and enterprise systems. Today many businesses can generate UI or prototype code using AI tools, but turning those ideas into secure, scalable, production-ready systems is where experienced engineering matters. That’s where I help. I work with startups, agencies, and growing companies to: • Architect scalable SaaS platforms • Integrate AI capabilities into existing systems • Refactor and stabilize AI-generated codebases • Design high-performance APIs and backend systems • Automate business workflows through smart integrations • Deploy reliable cloud infrastructure I’ve spent two decades building mission-critical software for leading organizations including: Postmedia, Hamilton Health Sciences, OrthoEvidence, Fleet Complete, GiftCash, Quote It Inc., and Prometheus Group (USA). These systems support real users, real revenue, and real operational workloads.
