I help companies turn complex technical problems into reliable, production-ready systems — whether that's a backend built from scratch, an AI agent that automates a manual workflow, or infrastructure that scales without breaking. My background spans backend engineering, data pipelines, cloud architecture, and enterprise warehouse systems, so I can usually see the full picture of what a project needs — not just the code. 💻 Software Development - Production APIs and services in Java, Python, and Go using Spring Boot, Django, Flask, and FastAPI. Multiple projects go live with my help in architecture backend - Enterprise-grade platform development: at Fortna, I built and customized Warehouse Execution Systems (WES) and Warehouse Control Systems (WCS), handling order orchestration, inventory management, and real-time integration with conveyors, sortation, and robotics in automated fulfillment centers - WES/WCS technical support — troubleshooting production issues, tuning order flow logic, resolving integration faults between software and material-handling equipment, and providing ongoing operational support for live warehouse systems 🤖 AI Agents & Automation - Designing agent workflows that handle real business tasks: data extraction, document processing, customer support, internal tooling, reporting - Building with Claude, Cursor, Codex, and LangChain-style orchestration to ship faster and cut manual work - Wiring AI agents into your existing stack — databases, APIs, dashboards — so automation fits your workflow instead of sitting on top of it 🗄 Databases & Data Engineering - Schema design and optimization across MySQL, MongoDB, Neo4j, and Redis - ETL pipelines and data warehouses, on-prem or cloud - Web scraping and data processing with Selenium, BeautifulSoup, Scrapy, Playwright, orchestrated via Airflow or Dagster ☁️ Cloud & DevOps - AWS and GCP deployment and management - Infrastructure as code with Terraform - Kubernetes for scalability - Monitoring with Prometheus and Grafana 🔐 Security & Digital Signatures - Digital signature workflows: PDF signing, PKI, CSC API - Tooling experience with iText, PDFBox, pyHanko, DSS Framework - Cryptography and HSM integration for compliance-driven projects

I build AI automation that actually ships and keeps running — n8n & Make workflows, AI agents, and RAG chatbots — on top of 10+ years of Python automation, web scraping, and data engineering. Top Rated Plus · 100% Job Success · 67 jobs · 4,000+ hours. Most freelancers can drag-and-drop a no-code flow. Almost none can get the data in. Pulling it from sites that don't want to give it up, cleaning it, and feeding it reliably into your systems — that's the hard half, and it's what I've done at scale for a decade. It's also why my automations don't break in week two. What I can build for you: ▸ Web scraping & browser automation — large-scale extraction from difficult sources with Python, Scrapy, Selenium, and Playwright: proxies, anti-bot handling, login flows, and browser agents that click, fill, and navigate like a person. The data layer most AI projects fall over on. ▸ AI automation & agents — n8n / Make workflows with AI steps that classify, extract, summarize, and decide; multi-step AI agents that use tools and take action (Claude, GPT, Gemini). ▸ RAG chatbots — assistants that answer from your own documents and data, with every answer grounded in a cited source (PostgreSQL/pgvector, embeddings, hybrid search). ▸ Data pipelines — ETL, enrichment, monitoring, and scheduled jobs that keep running unattended, with error handling and alerting built in. ▸ Integrations — HubSpot, GoHighLevel, Airtable, Google Workspace, Slack, Telegram/WhatsApp, REST APIs, and webhooks. Why the scraping background matters for AI work: an AI agent is only as good as what you feed it. Garbage input, confident nonsense out. I handle acquisition, cleaning, and delivery — so the AI layer on top has something real to reason about. How I work: ▸ Consult first, then automate — we fix the real bottleneck, not just the obvious one. ▸ Every build ships with source code, documentation, and error handling, so it survives the handoff. ▸ Clear, proactive communication on US-friendly hours; honest about scope and cost up front. 10+ years in software, a Master's in Cyber Security, and a track record clients describe as creative, thorough, and reliable. If a workflow is eating your team's hours — or you have an "AI setup" that sounds impressive but doesn't solve anything — message me with what's slowing you down, and I'll tell you exactly how I'd automate it.
