I build databases and custom Enterprise Resource Planning systems using Airtable, Zapier, On2Air actions and other API-friendly apps. I initially built an ERP system for my precision machine shop in central Florida and now offer these services to other companies. Airtable can store information in a spreadsheet that's visually appealing and easy-to-use, but it's also powerful enough to act as a relational database that businesses can use for customer-relationship management (CRM), task management, project planning and tracking inventory. Product Data Management (PDM) is the architecture of the data storage system. Typically in small-to-medium-sized companies, data structure is 'create a series of customer-job-part/product folders', and put the customer data there. This data structure is rarely planned for growth, and all the processes rely on humans following some homegrown process of manually creating nested folders. These processes are ripe for typing errors, people not aware or not caring about following protocol, and simply nothing that truly tracks the location of the data being stored. PDM, in a nutshell then, is the organization, storage, and retrieval of any data that might be tied to a manufacturing process. Airtable is ideal for not only storing data but managing workflow. I can create a database for you/your company and help automate routine tasks. My Process 1) Business Analysis & Data Modeling - Airtable is a database and database design requires some expertise. A 2-step process is completed. ▪ Business Analysis - Understand and analyze your company’s processes and workflow. ▪ Data Modeling - Convert business concepts into a data structure. ▪ Deliverable - Entity Relationship Diagram (ERD) will give you a visual representation of your data model. 2) Airtable Base Setup & Automation - A new Airtable base is created from scratch, this is completely customizable and designed to fit your needs. ▪ Setup - A new Airtable base is set up – including the setup of the tables, views, formulas, and blocks. ▪ Automation - KPIs are set up along with dynamic and automatically populated indicators. ▪ Deliverable - Airtable base customized for your specific needs. 3) Test & Feedback - A thorough iteration of tests, review, feedback, and modifications are performed until the system fits your workflow perfectly. ▪ Testing - I will have you perform tests on the Airtable base developed with sample data that is provided to you. ▪ Feedback - Feedback is collected, and adjustments are completed to improve the functionality and user experience. ▪ Deliverable - Airtable base updated and improved based on your feedback. 4) Integration & Training - I will collaborate to explain the integration and assist with the training for your new Airtable base. ▪ Integration - Airtable is connected to other API-friendly apps using Zapier. ▪ Training - An initial training workshop is scheduled to demonstrate the functionalities of the Airtable base. Another follow-up session will be conducted after you have had the opportunity to use your Airtable base ▪ Deliverable - Fully integrated Airtable base, plus training.

I first discovered my passion for programming when I was 12yrs old after getting a book to learn C++ in 21 days. I'm grateful to have gotten such a start as the lessons I learned then both in programming and object oriented design have stayed with me through my entire journey. Eventually I moved on to learn other languages like Visual Basic, Liberty Basic, Python, PHP, JavaScript, Lua, Java, etc., etc. I programmed primarily as a hobbyist for about 16 years working on projects that interested me that I could learn from until I finally broke into the industry professionally in 2016. I started as a web developer and was quickly moved up to a SR Engineer as my experience clearly shined through. I had the privilege of getting to learn and work on a large team of developers that followed a strict dev ops process to ensure that we worked together to deliver on excellence. Since 2016 I have specialized in NodeJS applications. Mostly on a MEVN stack (Mongo, Express, VueJS, Node) using NuxtJS for the front-end and MoleculerJS Microservices for the backend. I am well versed with this stack and every part of the development process that it entails. I can help you plan, build and deliver your next business application or project all the way from gathering requirements to actually implementing the solution. I work quickly and efficiently and deliver quality solutions that stand the test of time. My longest running software in production so far actually had an 8 year run (it was a simple JavaScript UI for expediting note taking and troubleshooting for Medtronic Diabetes pump support specialists, they just retired it last year for something that fully integrates with SAP). I consider myself an especially great asset to startups and small-medium sized organizations due to my wide range of experience and my ability to perform in various roles surrounding software engineering. Not only can I help you develop an amazing business solution, but I can help your team implement and follow a proper dev ops process and teach them to achieve success.

Enterprise AI Agent & RAG Architect. I help enterprise organizations eliminate LLM hallucinations, slash operational overhead, and scale intelligent document automation.I engineer custom, production-grade RAG pipelines and Intelligent AI OCR architectures that deliver deterministic data workflows with a verified 96.8% field-level accuracy across 10,000+ complex corporate pages. If you are dealing with standard vector-search chatbots that hallucinate, lose context, or fail to read dense data tables, or if your legacy OCR tools are outputting broken, chaotic text from blurry scans, faxes, and invoices, I build the automated bridge to clean, database-ready structured data. Unlike generalist script-writers who blindly dump data into basic vector stores, I design enterprise-ready, layout-aware, cost-optimized pipelines engineered specifically for highly confidential, unstructured, multi-column, and multi-page corporate assets. CORE WORKFLOWS & SEARCH-OPTIMIZED ARCHITECTURES: 1. Agentic production RAG Pipelines & Enterprise Knowledge Bases • Advanced Hybrid Search Indexing: Fusing dense semantic vector embeddings (Pinecone, Qdrant, ChromaDB) with sparse keyword retrieval (BM25) to guarantee specific alphanumeric codes, legal sections, and invoice serial numbers are never missed during a query. • Two-Stage Context Reranking: Implementing Cross-Encoder Rerankers (Cohere Rerank, FlashRank) to filter retrieved document nodes down to the absolute best context chunks, slashing downstream LLM token costs by up to 40% while accelerating system execution speed. • Layout-Aware Hierarchical Chunking: Parsing structured document layouts natively to maintain strict parent-child context windows, preventing sentences or complex financial data tables from being blindly split in half during vector indexing. 2. Intelligent AI OCR & Multi-Modal Document Intelligence • Vision-Based Pre-Processing: Utilizing OpenCV, PaddleOCR, and LayoutLMv3 to automatically de-skew, binarize, and map out the multi-column reading order of messy scanned PDFs, faxes, or smartphone images before running extraction. • Multi-Modal LLM & Vision Data Extraction: Routing raw text tokens and visual patches through state-of-the-art vision-language models (GPT-4o, Claude 3.5 Sonnet, or local open-source models like Llama-3.2-Vision and Qwen2.5-VL) to automatically repair transcription typos and misaligned characters by understanding the surrounding industry context. 3. Schema Enforcement & Human-in-the-Loop (HITL) Guardrails • Strict Schema Enforcement: Employing programmatic validation frameworks like Instructor and Pydantic to mathematically force LLM outputs into 100% compliant, database-ready JSON, CSV, or SQL structures at the native API level. • Algorithmic Triage: Tracking model confidence log-probabilities. High-confidence data saves instantly to production databases, while low-confidence edge cases route seamlessly to custom Streamlit dashboards for rapid human validation. PROVEN ENTERPRISE CASE STUDIES & SUCCESS METRICS: • Enterprise Document Intelligence: Multimodal AI OCR, Pydantic Extraction & Hybrid RAG Pipeline Designed and engineered an end-to-end production pipeline to automate the processing of dense, unstructured corporate assets (including scanned PDFs, financial statements, and high-volume faxes). Used LayoutLMv3 to preserve structural hierarchies and the Instructor library paired with strict Pydantic schemas to achieve an elite 96.8% verified field-level extraction accuracy across 10,000+ pages. • AI OCR Automation for High-Volume Faxes: Engineered a highly resilient extraction and contextual text-cleaning pipeline running flawlessly for complex, handwritten and blurry business records. • Markdown Data Extraction Specialist: Built a hyper-accurate pipeline converting complex document styles into structured markdown format for seamless vector indexing and RAG ingestion • Enterprise Document Parsing: Consulted on and deployed custom backend AI microservices to clean, parse, and automate unstructured multi-page document flows. MODERN PRODUCTION TECH STACK: • LLMs & Vision-Language Models: GPT-4o, Claude 3.5 Sonnet, Llama-3.2-Vision, Qwen2.5-VL, DeepSeek-VL2 • Frameworks & Validation: Instructor (Pydantic), LangChain, LlamaIndex, vLLM, Ollama, LangGraph • OCR & Computer Vision: Tesseract OCR, EasyOCR, PaddleOCR, OpenCV, LayoutLMv3, Marker, Text Extraction, Structured Outputs (JSON Enforcement) • Infrastructure & Vector DBs: Python, AI Chatbot Development, VectorDBs (Pinecone, Chroma, Qdrant), PostgreSQL, Docker, Data Scraping, Web Scraping, PDF to Excel Ready to eliminate hallucinations, protect your data privacy, and automate your critical document workflows with deterministic accuracy?
