  6. Ramp

    • Principal Software Engineer (IC7/Director)
      Jul 2023 - Oct 2024 · 1 yr 4 mos

      During my first month at Ramp— I brought bidirectional communications to the company’s communication platform. I built a system for engineers to target “chat” (slack and teams to start) with full interactivity. Buttons, forms, threads, replies etc. Allowing other feature teams (such as procurement) to deliver important notifications such as approvals to the place where the approvers are (chat). Afterwards I build up a vendor grade saas style solution to solve for “Compliance”. It turns multi-vendor, multi-region compliance needs such as KYC/KYB into a simple system with a unified interface. It had one goal in mind— reduce the friction (save time and money) of onboarding business’s to features that require compliance. It unified data collection so that multiple workflows can safely and securely interact with encrypted data from multiple sources. Turning an annoyance into a solved problem that did not require ongoing headcount or maintenance. It was designed as an “off the shelf” self-service product in the same way that Twillio solves for SMS and Stripe solves for card payments. Instead feature teams own the compliance of their products— as they should since they are the ones working with the vendors. We just orchestrate the storage, collection and approval of such things. Next, I helped another engineer launch a platform (due to the bus test), and I sanded down the sharp edges so that it would be an easier platform for our internal users. After that, I designed and started building a replacement to some of the oldest code at Ramp— handling credit card transactions. I also have volunteers for on-call duty— and mentored engineers across the org. Role: Python backend IC

  7. Pawp, Inc · Full-time

    • Director, Software Engineering
      Sep 2021 - Jun 2023 · 1 yr 10 mos

      At Pawp, I built systems for the CTO that would start as one sentence. “Our users should be able to book paid calls with a marketplace of pet professionals”. I would then architect, construct and deliver that system in the fastest timeline possible. I built: * referral system— i was asked to build this twice— but i only built it once as i made the side-effect of the referral fully pluggable. * an awesome scheduling system that involved a pythonic way of dealing with booking slots. A range of datetimes, and a booking interval, would create an object of “Slots”. This object functioned as an iterable list in python, so you could just loop over slots without the surface area for making time related mistakes in any business logic. If fully encapsulated datetime math so that it was solved in one place. (It also did more, but that was my favorite). * a prototype card issuing, authorization and transaction platform (serverless). * other small features * i also surgically performed a difficult migration in graphene/graphql tooling without requiring touching existing code. Role: Python backend IC. Was involved with sourcing, recruiting and hiring backend engineers

  8. Curex

    • CTO
      Jan 2020 - Aug 2021 · 1 yr 8 mos

      Built up a D2C healthcare product from scratch. Hired managed and led the engineering organization after building the initial GTM v0 launch. Performed all the expected CTO responsibilities around non-engineering technology as well. (But thats less exciting to talk about). Role: Backend (Python), frontend (TypeScript w/VueJS), infra (AWS), devops, IT, people management and leadership.

  9. Capital One

    • Director, Software Engineering / Distinguished Engineer ( @ Paribus/WikiBuy/Jewel )
      Oct 2016 - Jan 2020 · 3 yrs 4 mosNew York City Metropolitan Area

      2016-2018: After Paribus was acquired, I had some downtime due to successful delivery of projects pre-acquisition. So I started up the mailbox project— which was supposed to have a newly hired team assigned to it. Before a single candidate was reviewed, I had a fully working prototype, and not long after it was running production workloads in tandem with our previous system. Mailbox was fully serverless and had zero downtime or incidents. I had such confidence in the system that I offered myself to be fully on-call: 24/7/365. I highlighted the “bus test” as the only vulnerability of the project after it went through a full process of security and other review processes. I hired and managed one engineer to remediate the “bus test” weakness— but spared them of on-call duty and remained fully on-call until I transitioned to a new role in the company. The mailbox project saved the company 7-8 figures annually— after all costs including my salary. 2018-2020: I offered to help Capital One with their acquisition of WikiBuy. I had been on the other side of acquisition— and Capital One as a whole was aligned with reducing that friction for further acquisitions… There wound up not being a lot of work to be done for that specific role, so I created other initiatives to help with the ongoing digital transformation as the company. This included creating and conducting an engineering-only onboarding session— so that new hires would be able to report to their managers without any friction of working in a regulated environment with proxies. This included orientation on using everything from GitHub to CI/CD to AWS. The experiment was a success but I left in early 2020 after the migration I had been assigned to ended. I recommended myself as a lay-off because the team was overstaffed. Role: Python Backend IC, Brief people management (due to building sustainable systems that did not require headcount)

  10. Paribus Co.

    • Director, Software Engineering
      Jun 2016 - Jan 2020 · 3 yrs 8 mosNew York City Metropolitan Area

      Automating and spreading my money saving addiction. (see: Capital One) During my time before the acquisition I was asked to pick one of three problems the company wanted to solve. They asked me to become an expert in that problem within 6 months, after which I would be able to hire a team. I solved the first two fully with thoughtful architecture and design within two months. After we got acquired— a built a working prototype to “solve” the third problem within a month. The solutions i delivered were simple, elegant and resilient. They had zero downtime- and for the third— were fully multi-region. Role: Python Backend IC. I delivered solutions that did not require headcount or pager rotations. As a result— I offered to be on call 24/7/365.
