With over 100 projects completed on Upwork and experience dating back to the earliest days of the web, I build robust backend architecture that works the first time. I Make Systems Talk to Each Other — HubSpot, Jobber, WooCommerce, Mailchimp, Salesforce, FieldAware, Workyard, and more. If your CRM, website, or field-service tools aren't syncing the way they should, that's exactly the problem I solve. Recent Work: • HubSpot & Jobber Sync — a custom Python listener and PHP-based integration automating real-time client sync (Create/Update) and job lifecycle automation via high-performance webhooks, built when Zapier and native integrations weren't cutting it. • Custom WordPress Booking Plugin — full Jobber GraphQL API integration for a service-industry client, including a self-service cancel/reschedule flow, taken from early development through staging acceptance. • Field Service Software Integration — built in Airtable with TypeScript automations, connecting two different field-service management platforms (FieldAware and Workyard) so job and crew data flow between them automatically • Large-Scale Data Pipeline — a Python/PHP deduplication and normalization pipeline for a veteran employment nonprofit, processing 113 files and roughly 79,600 records. • Commercial Product Development — authored and released a WooCommerce/Authorize.net payment gateway plugin (CIM vaulting, auth-only checkout with manual capture, subscription billing, debug logging) with LemonSqueezy license management, plus a Python Gmail API bulk mailer tool. Core Expertise: • Python & FastAPI — modern, asynchronous, strictly typed APIs • API Integration & ETL — REST, GraphQL, and legacy SOAP services • PHP & Backend Systems — custom architecture, Laravel, and database optimization • Data Architecture — custom SQL design and complex JSON transformations Why Work With Me: You are hiring a Subject Matter Expert, not a junior developer. I do not outsource, I do not subcontract, and I do not require hand-holding. I translate business requirements into production-ready code that is documented and resilient.

I build production-ready AI agents that bridge the gap between "cool prototypes" and actual business ROI. As a Computer Science student at UCF with a background in high-stakes algorithmic logic, I don’t just write prompts—I build scalable, autonomous systems. I specialize in multi-agent workflows and intelligent data processors that save businesses 10–40+ hours per week by automating complex manual tasks. What I Deliver: * Custom Multi-Agent Workflows: Designing "swarms" that handle lead qualification, CRM automation, and document parsing using LangChain and CrewAI. * MCP-Powered Integration: Implementing the Model Context Protocol (MCP) to give your agents secure, reliable access to your local files, APIs, and databases. * Data Intelligence: Advanced web scraping, structured extraction from PDFs/CSVs, and predictive modeling for actionable insights. * Financial & Quantitative Logic: Expert in algorithmic trading bots and strategy optimization (Pine Script, MT4/5, Genetic Algorithms) for high-performance financial workflows. Why Work With Me? * Engineering Mindset: A strong CS foundation means I focus on error handling, security, and performance—not just "chatting" with an LLM. * Outcome-First Approach: I provide clear milestones and fixed-price scoping so you know exactly when your system goes live. Let’s discuss your workflow pain points. I’m happy to audit your current process and propose a scoped solution that actually moves the needle.
