Background & Vision

Where Software Precision Meets Engineering Execution

A multidisciplinary mindset dedicated to architecting clean code, automated workflows, and tangible real-world systems.

Enterprise Automation & Pipelines

Experienced in creating end-to-end automation pipelines that solve tangible business bottlenecks. During my internship at Sapi Technologies, I engineered automated ingest bots handling WhatsApp messages, PDF purchase orders, NLP fuzzy customer matching, and direct synchronization with production SQL Server ERPs.

HVAC & Mechanical Airflow Design

My hands-on experience at New Results Heating & Cooling gave me deep mechanical engineering intuition. Designing complete air duct layouts for newly constructed homes required calculating CFM airflow, static pressure balance, duct friction rates, and spatial routing within architectural floor plans.

Full-Stack & Systems Architecture

From web platforms like ATX Teens Need Jobs built with modern responsive frontends and Supabase databases, to mobile synchronization apps (EVO App) and CustomTkinter desktop applications, I design intuitive user experiences backed by reliable database schemas.

Software Engineering Intern

Sapi Technologies LLC

Internship Austin, TX

Architected and deployed SAPI_WATCHER, an automated multi-service order processing pipeline that streamlined inbound order ingestion from communication channels into enterprise ERP systems.

โšก
Automated Message & PDF Parsing: Engineered a Node.js listener and Python Flask backend that ingests incoming customer WhatsApp orders, parses attached PDF purchase invoices via PyMuPDF, and stages verified orders into PostgreSQL.
๐Ÿ”
Fuzzy NLP Matching: Implemented intelligent customer and item matching algorithms that accurately mapped unstructured chat messages and colloquial item names to master enterprise product catalogs.
๐Ÿ–ฅ๏ธ
Desktop Admin Dashboard: Developed a CustomTkinter GUI featuring QR code authentication, live streaming logs, order queue management, interactive editing modals, and human-in-the-loop review.
๐Ÿ—„๏ธ
Remote Production SQL Sync: Configured ODBC pipelines to remote MS SQL Server, auto-populating customer profiles, tiered pricing schedules, and pushing confirmed orders directly to the active ERP.

New Results Heating and Cooling

Engineering Texas

Designed complete residential air distribution and ventilation systems for new custom home developments, ensuring optimal thermal comfort, quiet operation, and strict compliance with energy efficiency codes.

๐Ÿ“
Airflow & CFM Calculations: Calculated room-by-room heating and cooling CFM requirements and external static pressure (ESP) using ACCA Manual D and Manual J design methodologies.
๐Ÿ 
Blueprint & Spatial Routing: Analyzed architectural framing plans to design trunk-and-branch duct systems, carefully avoiding structural headers, load-bearing joists, and plumbing risers.
โš–๏ธ
System Balancing & Static Pressure: Optimized plenum transitions, damper placements, and return air pathways to prevent pressure drops and maximize HVAC heat-pump efficiency.
๐Ÿค
Cross-Trade Collaboration: Partnered directly with general contractors, architects, and field installation crews to verify dimensional tolerances prior to drywall installation.
