This project implemented an AWS IoT solution for 20,000+ on-field reader devices, enabling seamless over-the-air firmware updates for fleet-wide efficiency and reliability. It also enhanced monitoring and reporting by integrating AWS IoT lifecycle events, improving connection status accuracy, and integrating Memfault reporting logic for increased visibility on debug chunks.

Additionally, back-end services were migrated from a legacy in-house framework to a modern spring-boot framework, enhancing observability and maintainability.

I operated with a high degree of autonomy while collaborating with a product manager, a staff engineer, and a QA engineer. Together, we iterated on both functional and non-functional requirements and conducted biweekly demos to showcase my progress.

This is a digital-first corporate banking-as-a-service (BaaS) platform built from scratch. I built solutions that revolutionized the onboarding and account opening experience, which shortened these processes' time to minutes from the industry standard of months. This was achieved by supporting external clients (partners) and internal operations to perform self-service driven by API and UI.

The project aims to integrate Dwolla and Stripe payment processors to support, send and receive deposit and rent payments and multiparty payments via Express Checkout, respectively. This also includes accounts onboarding, management, and different payment scenarios. These functionalities empower user experience in building services and management.

I oversaw requirement refinement, design, implementation, and testing during SDLC and worked closely with corresponding parties, including the product manager, development team, security team, and QA.

A loan eligibility checking/slotting process orchestrated by Camunda 8 in the back end. I led the back-end development team in Springboot and Camunda and mentored and guided offshore dev resources from different vendors to extract core proprietary orchestration logic.

As part of the payments team, I was responsible for payment methods and providers' integrations such as card, Apple Pay, Alipay, WeChat Pay, and Google Pay. Apart from an integration perspective, achieving high availability, fault-tolerance, scalability, and providing observability to both the business and team were also my main deliverables.
