Christo A.

I build modern, stable, API-connected FileMaker systems for companies who need more than just a developer. I am a Senior FileMaker Architect and Systems Integration Engineer with more than 15 years of experience designing high-performance FileMaker solutions, building API-driven workflows, deploying FileMaker Server on Linux and Docker, and integrating automation using Python, FastAPI, OCR, and AI. If you need your system to be faster, smarter, automated, scalable, or integrated with the outside world, I can help you achieve that. WHAT I DO Complete FileMaker System Architecture and Builds I design and build full FileMaker systems from the ground up, including modern UI and UX, structured layouts, properly planned schema (anchor buoy methodology), fast scripting, workflow automation, and documentation for smooth handover and long-term maintainability. API Integrations This is one of my strongest areas. I connect FileMaker to services such as DocuSign, Xero, payment gateways, CRM and ERP platforms, Microsoft Graph, email systems, accounting systems, custom web platforms, and OCR or AI-based services. I handle authentication, OAuth 2.0, token refresh systems, webhooks, secure communication, and large-scale two-way syncing. Python and FastAPI Services for FileMaker I build external services when FileMaker needs extra power. These include OCR pipelines for scanned documents, PDF and text extraction processes, AI semantic search, REST APIs that FileMaker communicates with, background automation workers, scheduling systems, and secure endpoints for portals and mobile apps. If FileMaker cannot do it internally, I design the external engine that handles it. FileMaker Server Deployments (Linux, Docker, Cloud, or On-Prem) I configure FileMaker Server environments that are fast, secure, stable, and fully backed up. I have deployed FileMaker Server on Ubuntu Linux, Docker-based systems, Windows Server, hybrid WebDirect systems, and multi-machine environments. I also build custom CLI management tools to simplify system administration and improve reliability. System Modernisation, Fixing, and Optimization Even well-designed systems slow down or become unstable over time. I specialise in improving existing solutions, including performance tuning, relationship graph cleanup, fixing broken scripts, repairing data workflows, rebuilding fragile modules, replacing old PHP or Lasso integrations with modern APIs, hardening security, and extending system lifespan through proper redesign. Sometimes a system needs a light improvement, sometimes it needs a targeted rebuild, and when a full rewrite is the best long-term choice, I will say so honestly. AI AND LLM INTEGRATION I integrate AI and LLM technologies into FileMaker and Python systems to automate processes, extract structured data, and enhance decision making. I build FastAPI based services that act as intelligent extensions to FileMaker, allowing the system to perform tasks that are not possible natively. This includes OCR for scanned documents, text extraction from PDFs, automated classification, data cleanup, and semantic search to help users find information more efficiently. I also create LLM powered endpoints that FileMaker or external applications can call. These endpoints can summarize content, generate structured JSON, classify records, interpret natural language queries, or provide intelligent responses based on your data. I design these services with security, performance, and reliability in mind, using Python, FastAPI, and modern AI models. My focus is on practical AI that solves real business problems, improves accuracy, and reduces manual work. Whether you need automated document processing, AI assisted workflows, an LLM powered API, or a hybrid FileMaker and Python engine, I can build a solution that fits your environment and integrates seamlessly with your existing systems. WHY CLIENTS HIRE ME I communicate clearly and professionally. I deliver stable, scalable architecture rather than quick patches. I understand FileMaker as well as the infrastructure around it. I build systems that last and that teams can maintain. I integrate AI, OCR, and automation when it adds real value. I can design, build, fix, optimize, or expand any FileMaker system. I help companies modernize and future-proof their entire workflow. I do not approach projects as a junior developer. I approach them as someone who builds business-critical systems that companies depend on every day.
