# Pratik Sampat > Senior Software Engineer | Ruby on Rails · ML Platforms · Document AI Location: Greater Chicago Area, United States Profile: https://flows.cv/pratiksampat I’m a tinkerer at heart no doubt. I'm energized by startups and curious, messy problems. I love learning new tools, shipping prototypes, mentoring teammates, and building platforms that make AI/ML actually useful in the real world. I do the pragmatic plumbing: from preparing data and document pipelines to the auth, infra, and ops that teams need to run AI reliably at scale. My thing is turning experiments into repeatable systems that reduce risk and speed product teams forward. I get a kick out of rapid POCs that expose tradeoffs and help teams decide whether to scale. My prototypes have ranged from AI-driven document classifiers to platform experiments that speed migrations and improve developer productivity. I’m happiest when I’m shipping, learning, and helping others ship too. Let’s chat! ## Work Experience ### Senior Software Engineer @ Ontra Jan 2024 – Present Led cross-cutting platform work to improve authentication, document infrastructure, and developer & operational tooling. This ultimately enabled driving higher reliability, faster document processing, and scalable ML-enabled document workflows across Ontra products. • Centralized document stores and migrations across Ontra to provide consistent, searchable corpora for ML experiments and production models. • Built several POCs (Filepicker, permissions, soft deleting documents) to validate safe access patterns and improve repository hygiene. • Built a "Document Organizer with AI" POC - a document classifier that enabled rapid, human-in-the-loop organization of implementation artifacts. I used OpenAI/ChatGPT, prompt engineer, PDF parsing and automated packaging for classification of documents. See "Projects" for more detail. • Designed and delivered ML-ready document infrastructure: an ingestion & document pipeline (Textract → consolidated JSON → JSONL) to make documents consumable by downstream ML (classification, extraction, LLMs). • Improved platform reliability and performance (SQL and infra optimizations, Terraform work) so ML jobs and document APIs run predictably at scale. • Shipped auth/session platform improvements (Universal Login and SLO design) and operational runbooks so cross-app ML pipelines run under consistent security and session semantics. ### Software Engineer @ Ontra Jan 2022 – Present Delivered product foundation work to scale authentication, billing, and support, while building the primitives ML teams later used. • Implemented Universal Login (Auth0/Okta/SSO), Single Logout components and rollout plans, ensuring secure cross-app authentication for product and API access. • Built BillingPlatform integrations and migration tooling used by product teams; authored runbooks and scripts to ease operational maintenance. • Led addition of self-serve support features and improved CI/test stability to reduce support toil and accelerate safe rollouts of ML-facing features. • Authored developer tooling and docs to make local testing and model data preparation faster and more reliable. ### Software Engineer @ Grubhub Jan 2019 – Jan 2022 | Greater Chicago Area ### Software Engineer @ Vail Systems Jan 2018 – Jan 2019 | Greater Chicago Area • Utilize latest Ruby on Rails and JavaScript technologies to build new features on the RACC (Routing and Call Control) platform. • Write unit and integration tests with Cucumber, Capybara and RSpec to contribute to automated testing efforts. • Build single page applications (SPAs) using React and Angular • Work on a team of developers to coordinate the development of new features and maintain existing infrastructure. ### Technical Account Manager @ Vail Systems Jan 2016 – Jan 2017 | Greater Chicago Area • Created two Google Chrome Extensions to boost internal employee productivity by using browser APIs to navigate, redirect and perform every day actions in the browser. • Directly assisted Fortune 500 clients with porting of toll-free and local numbers, customer training/on-boarding, and routing phone traffic using RACC. • Designed four week on-boarding employee training program to introduce basic telephony concepts in an effective and structured manner. ### Program Coordinator - Knapp Entrepreneurship Center @ Illinois Institute of Technology Jan 2014 – Jan 2016 • Aid students, faculty, staff and alumni of IIT to launch ventures and provide additional resources to ensure a successful startup • Planned and organized events hosted by the Knapp Entrepreneurship Center • Frequently utilize Google Apps Script to automate client statistical data, registration responses, generating monthly PDF reports, and creating bi-weekly newsletters. • Published and sent monthly newsletter to communicate with clients ### Front End Web Developer @ Sage Education Jan 2011 – Jan 2012 | Bangkok, Thailand • Boosted company’s SEO rankings by improving digital presence and recruiting new customers. • Created and maintained mobile responsive Wordpress website (www.sageeducationth.com) to highlight new test preparation programs. • Organizing email campaigns, referral programs, and assisting with digital marketing ## Education ### Bachelor of Science (B.S.) in Engineering Management, Computer Engineering Illinois Institute of Technology Jan 2014 – Jan 2016 ### Full Stack Web Development BloomTech Jan 2017 – Jan 2017 ### Associate of Science (A.S.) in Computer Engineering Monroe Community College Jan 2012 – Jan 2014 ## Contact & Social - LinkedIn: https://linkedin.com/in/pratiksampat - Website: https://pratiksampat.com - GitHub: https://github.com/pratik0809 --- Source: https://flows.cv/pratiksampat JSON Resume: https://flows.cv/pratiksampat/resume.json Last updated: 2026-03-22
