# Caleb Leung > Software Engineer at IntellPro Location: New York City Metropolitan Area, United States Profile: https://flows.cv/calebleung Hi there! I am a first-generation recent graduate with a Mathematics bachelor's degree and a minor in Economics. As a software engineer, I am committed to the field of computer science and continually striving to enhance my skills. My work ethic, sense of responsibility, and determination were all cultivated during my childhood. From the age of six, I gathered recyclable materials by the Shing Mun River in Hong Kong SAR every weekend. My hobbies include chess, working out, playing basketball and American football, and studying math, physics, and computer science-related topics. Also, I love anime and my favorite anime is Evangelion. I'm always looking to connect with engineers working on large-scale distributed systems — if you've made interesting design decisions at scale, I'd love to learn from you! caleb-leung-kwan-ho.github.io/github-website/ Let's connect :) ## Work Experience ### Software Engineer @ IntellPro Jan 2024 – Present | New York, NY • Architected a high-throughput RAG pipeline to ingest and process SEC filings (10-K), implementing a custom parser that normalizes heterogeneous HTML/PDF content into structured formats. • Reduced cloud infrastructure costs by 100% ($10K/month) by engineering a custom OCR solution to replace AWS Textract, maintaining accuracy while improving processing speed and reliability. • Designed a custom chunking library tailored for financial documents, optimizing token usage and preserving tabular data integrity significantly better than off-the-shelf solutions like LangChain. • Implemented a hybrid search algorithm combining semantic (SentenceTransformers) and fuzzy matching (RapidFuzz) to align section headers across disparate documents, improving retrieval accuracy. • Built a document classification model achieving 98.5% accuracy by optimizing embedding strategies and scoring functions for financial data categorization. • Established a comprehensive CI testing suite using Pytest, covering the full data ingestion lifecycle and accelerating the release cycle by 20%. ### Software Engineer @ Coco’s Industries LLC Jan 2024 – Jan 2024 • Led the end-to-end development of a new Warehouse Management System (WMS) using FastAPI, delivering the project a full fiscal quarter ahead of schedule. • Designed and deployed scalable RESTful APIs to synchronize inventory data in real-time between the storefront and warehouse systems, ensuring 99.9% data consistency. • Engineered asynchronous background tasks using AWS Lambda and ECS Fargate to handle high-volume inventory sorting operations, decoupling business logic from the main application thread. ### Software Engineer @ LivestockCity Jan 2022 – Jan 2023 | New York, NY • Refactored legacy Django codebase to resolve critical model inconsistencies, significantly improving application stability and PDF rendering performance. • Developed a dynamic PDF generation engine, automating manual form creation workflows and reducing administrative overhead. • Optimized user communication protocols by implementing a robust email notification system integrated with core application logic. ## Education ### Bachelor of Science - BS in Applied Mathematics Baruch College ## Contact & Social - LinkedIn: https://linkedin.com/in/caleb-leung-a67b74168 - Website: https://caleb-leung-kwan-ho.github.io/github-website/ - GitHub: https://github.com/Caleb-Leung-Kwan-Ho - Website: https://gatech-csm.symplicity.com/profiles/caleb_leung --- Source: https://flows.cv/calebleung JSON Resume: https://flows.cv/calebleung/resume.json Last updated: 2026-04-01
