Worked on the Delinquency Team

• Main technologies: backend API on Python, front end web application on React, all hosted in Google Cloud

• Helped grow the number of loans Valon services from 50 to 50,000.

Built out greenfield products such as:

Mortgage Assistance

• enabled Valon to offer forbearance plans, repayment plans, payment deferrals, and loan modifications for borrowers who are experiencing difficulties paying their mortgage (over 250 plans plans so far)

• integrated with our proprietary payments ledger in order to automatically allocate payments to the plans and permanently modify the loan terms

• automated onboarding of previously existing plans from prior servicers to allow Valon to compliantly service these loans (onboarded ~400 plans with an expected load of 5,000 in 2023)

Collections

• integrated with Nice API (an automated dialer) to call delinquent borrowers dependent on a set of eligibility criteria, scaling the number of collections outreach from 300 to ~4k per month

• created a page in the internal console to consolidate relevant delinquency information for expedited customer support

Property Inspection

• integrated with a third party vendor to automatically determine when to order a property inspection and execute that order and ingest the results via SFTP

Other projects: Automatic Private Mortgage Insurance Cancellation, Bankruptcy, Foreclosure, Promise to Pays

Twilio Proxy

• Enabled Proxy to bring in revenue of >$1M/year by integrating with Twilio billing system

Billing Org: Transactions Team and Pricing Team

• Built scalable APIs to be able to handle hundreds of millions of requests a day (data validation, read/write from MySQL DB, logging, metrics, caching)

• Automated Calls Per Second billing for Twilio’s Voice product, reducing manual operation time by hundreds of total hours

• Implemented Quota API (a Scala + Akka HTTP API) to empower Twilio to bill in a completely different way: quota based instead of event based – allowed sellers to make million dollar deals with the Twilio Flex product

• Tools used: Python, MySQL, REST APIs, Spark, AWS, S3

I am a grutor (grader and tutor) for the introductory computer science courses at Harvey Mudd College: CS05 (Introduction to Computer Science), CS60 (Fundamentals of Computer Science), CS140 (Algorithms), and CS133 (Databases). I grade the students' homeworks each week and hold tutoring hours for students to come and ask questions.
