I build AI that ships to production
Engineer with a business-first mindset. With degrees in Supply Chain, Business Analytics, and AI, I don't just write code — I understand the operations, data flows, and revenue models behind what I build. From RAG pipelines to full SaaS platforms, every system I ship is designed to create measurable value.
What I Do
Services
AI Applications
Production AI systems — RAG pipelines, intelligent agents, document understanding, and LLM-powered features that solve real business problems.
Full-Stack Products
End-to-end SaaS platforms — from database design to deployment. Multi-tenant systems, real-time features, and scalable architecture.
Data & ML Pipelines
Large-scale data processing — ETL workflows, geospatial pipelines, automated ingestion from satellite imagery to API aggregation.
Selected Work
Projects that shipped
Production systems handling real users, real data, and real business requirements.
CodeDocs
Open Source CLI ToolAuto-generate complete documentation for any Python codebase using AI
Scans a Python project via AST parsing and generates full markdown documentation — architecture overview, API docs, database schema, setup guides, and per-module docs. Understands code logic, not just docstrings.
Vetly
Full SaaS ApplicationComplete pet health management platform for owners and veterinarians
Pet owners manage profiles, book appointments, track medications, and get AI-powered health summaries. Vets get patient management, scheduling, approvals, and analytics dashboards. Local LLMs (Llama-3) keep patient data 100% private with zero per-token costs. Deployed on Hetzner VPS with Grafana + Prometheus monitoring API latency, database performance, and uptime.
Future Cats
Enterprise AI ApplicationAI-powered document intelligence with dual-stream knowledge retrieval
Upload documents and ask questions in natural language. Dual AI responses — one grounded in documents with citations via Pinecone, one from GPT-4 for general knowledge. Includes collaborative whiteboard and usage tracking.
EcoDev AI Pipeline
Production Data PipelineAutomated environmental data ingestion from 7+ sources for AI model training
Collects and processes environmental data from Copernicus Sentinel-2, Google Earth Engine, weather stations, and APIs into PostGIS. Handles raster processing, coordinate transformations, and multi-resolution indices at scale.
EcoDev Lab App
Enterprise ToolField data collection platform for ecological surveillance operations
Web application for lab technicians to collect and manage ecological field data — supports multiple trap types, species classification, environmental readings, and geospatial mapping across regions.
Sports-Holics
Sports News PlatformGreek sports media platform with real-time news, scores, and journalist profiles
Full-stack sports news site covering football, basketball, and Formula 1. Strapi 5 headless CMS powers content management for articles, breaking news tickers, team pages, and journalist profiles. Dynamic routing, SEO-optimized pages, and a standalone promotional landing page.
Personal Infrastructure
Self-Hosted Home LabTrueNAS server running containerized services with full observability
Built and maintain a self-hosted TrueNAS server running multiple Dockerized services for personal storage, backups, and development environments. Instrumented the entire stack with Grafana + Prometheus dashboards tracking system health, disk I/O, container metrics, and storage capacity. Replaced multiple paid cloud services with locally hosted alternatives.
