Richie’s strongest areas are Python, Linux systems administration, infrastructure and platform engineering, PostgreSQL, OpenZFS, AI/LLM workflows, and automation. At Nornsight, he built ingestion pipelines for more than 250 million records and 100,000 documents, deployed BERTopic analysis across more than 250 million social-media posts, and fine-tuned and served 4B and 8B LLMs on self-hosted NVIDIA GPUs. Previously, at Wells Fargo, Richie developed Python backend automation and secure REST APIs that reduced operational risk and improved team efficiency, while helping raise test coverage to 100% for lines and branches and maintaining 95%+. His infrastructure experience includes cutting provisioning from two hours to two minutes, delivering a 60x deployment-speed improvement through automation, and supporting reliable production systems across 100+ deployments. Earlier, at Stevens Institute of Technology, Richie administered Linux systems, deployed LDAP for more than 100 users, managed OpenZFS/NFS storage, and supported network penetration testing. ## Services - vllm - Data Science - Artificial Intelligence \(AI\) - Data Engineering - Small Language Models \(SLMs\) - Large Language Models \(LLM\) - Continuous Integration and Continuous Delivery \(CI/CD\) - GitHub - Technical Requirements - Systems Design - Computer Science - Integration Testing - Code Review - Microsoft Azure - Cloud Computing - Powershell - Debugging - Git - Test Automation - Software Design - Engineering - Software Infrastructure - Pydantic - PostgreSQL - Jira - Flask - SQLAlchemy - Pivotal Cloud Foundry \(PCF\) - Rust \(Programming Language\) - Switchboard ## Highlights - Owns all engineering and infrastructure for Nornsight’s self-hosted ML and data platform, from hardware and operating systems through pipelines, model serving, deployment, and frontend delivery. - Built PostgreSQL ingestion pipelines for more than 250 million records and 100,000 documents using weekly partitioning, SQLAlchemy/Alembic, and COPY-based bulk loading. - Deployed BERTopic across more than 250 million social-media posts to extract and track topics for downstream analysis. - Fine-tuned 4B and 8B LLMs with Unsloth using QLoRA and served them with vLLM on self-hosted NVIDIA GPUs. - Built a two-pass LLM summarization pipeline. - Built a platform web frontend with HTMX on a FastAPI backend. - Tuned OpenZFS for write-heavy ML workloads by isolating the write-ahead log to Intel Optane and configuring recordsize and compression per dataset. - Created Python automation at Wells Fargo for Jira-ticket and Grafana-dashboard management reporting. - Built a REST API at Wells Fargo to replace waits for batch jobs. - Architected and built a secure, immutable remediation-evidence API using PostgreSQL, SQLAlchemy, and blob storage. - Helped onboard four Wells Fargo employees, including one principal engineer. - Introduced the Ruff linter to improve coding standards at Wells Fargo. - Raised a Wells Fargo codebase to 100% line and branch coverage and maintained coverage above 95%. - Created a shared SQLAlchemy library, implemented Pydantic data validation, and created Splunk batch-job alerts at Wells Fargo. - Delivered infrastructure automation for MQ appliances using Ansible and infrastructure-as-code practices. - Reduced provisioning time from two hours to two minutes, delivering a 60x deployment-speed improvement. - Built reliable production systems that scaled across more than 100 deployments. - Built custom Python and Paramiko interfaces for non-standard SSH automation and legacy interfaces. - Administered three Linux servers and 24 Linux client systems at Stevens Institute of Technology. - Deployed LDAP authentication at Stevens Institute of Technology for more than 100 users. - Managed centralized OpenZFS and NFS storage at Stevens Institute of Technology. - Installed and managed CoppeliaSim, OMNeT++, and Xilinx Vivado at Stevens Institute of Technology. - Collaborated with a Capture the Flag team on network penetration testing at Stevens Institute of Technology. - Worked with a team to process 300,000 federal-election ballots at the Ocean County Election Board while following non-partisan laws and federal standards. - Holds Microsoft Certified: Azure Fundamentals and CompTIA A+ certifications. ## Experience - **Senior Software Engineer at Nornsight** (2026-01-01–present) — Own all engineering and infrastructure for a self-hosted ML and data platform, from hardware and OS through data pipelines, model serving, and deployment. Built PostgreSQL ingestion pipelines for 250M+ records and 100K+ documents with weekly table partitioning \(SQLAlchemy/Alembic\) and COPY-based bulk loading. Deployed a BERTopic topic model and ran it across 250M+ social media posts to extract and track topics for downstream analysis. Fine-tuned 4B and 8B LLMs with Unsloth \(QLoRA\) and serve them with vLLM on self-hosted NVIDIA GPUs built a two-pass summarization pipeline. Built the platform's web frontend with HTMX on a FastAPI backend. Tuned OpenZFS for write-heavy ML workloads: isolated WAL to Intel Optane and set recordsize and compression per dataset. - **Software Engineer at Wells Fargo** (2022-11-01–2026-01-01) — I work primarily in python to create backend business automation that reduces risk and improve team efficiency. I did this by creating automation to manage jira tickets and grafana dashboards for management reporting. I then improved this by creating a rest api so we would no longer have to wait for batch jobs to run. I then architected and created a rest api to securely and immutable collect evidence of remediation. This was done by creating a rest api that stored evidence metadata in a postgres database using sqlalchemy and the evidence files in blob storage. other accomplishments include: - I have helped onboard 4 new employees 1 of with is a principal engineer. - I Improved our coding standards by introducing the team to the RUFF linter. - I got our code base to 100% coverage \(lines and branches\) and now maintain 95%+. - I created a shared library for our sqlalchemy code. - I created splunk alerts to monitor our batch jobs. - I set up Pydantic to validate data. - **System Administrator at Stevens Institute of Technology** (2021-09-01–2022-11-01) — Instructing students in the proficient administration and troubleshooting of Linux systems.
