Full-Stack Software Engineer

I took the application from technical discovery through production support, working across the client, AWS, online banking, and core banking systems.

Authentication and financial data had to move between our application, an external online banking platform, internal APIs, and the core banking system.

I used Cognito as the authentication and authorization boundary for the systems connected to the application.

I led the production launches and managed the authentication workflow between the online banking platform and the embedded application.

The product ran in an iframe, and third-party cookie restrictions broke session creation in some browsers, particularly on Apple devices using WebKit.

I reproduced the failures across browsers, traced them to the cookie dependency, and worked with the vendor to change how sessions were created. I also advised the vendor on authentication for its server-rendered application.

I built the application and moved the team from separate manual reports to one shared workflow.

Employees worked across time zones, countries, and roles. Project managers, accounting, billing, and leadership each needed a different level of reporting detail.

Rather than reproduce each department's manual process, I worked with stakeholders and employees to define one centralized weekly workflow.

I worked on a three-person team and built the search, category filters, vendor and market registration forms, and OpenStreetMap integration. I also handled the Vercel and Neon deployments.

Information about street markets was fragmented across informal sources. The application needed to organize locations, schedules, categories, markets, and vendors without making discovery feel like a database search.

We used a relational PostgreSQL model for the market data and combined filters with an OpenStreetMap interface so people could search by how they actually choose a market: place, day, or category.
