Professional Experience

Apiphani Remote | 2025 to Present

Lead Software Engineer

After a year of contract work with Apiphani through TradeOff, I joined the team full-time to keep building the platform I helped get off the ground. Today my focus is a desktop application that lets IT teams manage and troubleshoot their servers with the help of AI, along with the monitoring and API layers that feed it.

AI-Driven Server Management App: I build a cross-platform desktop application in Electron with a TypeScript/React frontend and a Go backend. It gives operators one place to connect to their servers, run commands, and work alongside an AI assistant that can dig into problems, explain what it finds, and help resolve them. Much of my work goes into making that experience feel fast and dependable, so engineers can trust it on real production systems.
Server Monitoring Service: I developed a lightweight Go service that runs on customer servers, similar in spirit to tools like Dynatrace. It securely executes bash scripts, analyzes system files, and collects system and application data, giving the desktop app an accurate, up-to-date picture of each environment, including complex SAP landscapes. The same data powers the platform's automated, auditable compliance reporting.
Platform APIs: I design and maintain the Go and TypeScript APIs behind the desktop app, growing the GraphQL services from the original compliance platform into a backend that connects the client, the monitoring service, and the AI features into one coherent product.

Senior Full-Stack Software Engineer

As a senior consultant and engineer, I partner with a diverse portfolio of clients to solve their most pressing technical challenges. I lead the end-to-end project lifecycle—from architectural design and strategic roadmapping to hands-on development and deployment—delivering bespoke, high-impact software solutions that drive business growth and operational efficiency.

Enterprise Server Compliance & Automation Platform: For a major SaaS client, I architected and built the first version of a full-stack automation platform to solve a critical operational bottleneck: manual server compliance checks on enterprise servers, including SAP environments. I engineered GraphQL APIs in Node.js/TypeScript to ingest and process the compliance data, along with a real-time monitoring dashboard. This solution eliminated hundreds of hours of manual IT work monthly and provided 100% accurate, auditable compliance reporting.
Strategic Payment System Migration: I led a high-stakes migration of a legacy payment system from Stripe to Chargebee for a client in the legal travel sector. I orchestrated the entire technical transition for their Django-based platform, ensuring zero-downtime and preserving data integrity for all recurring subscriptions. The project involved re-architecting payment processing workflows and managing complex data mapping, ultimately preventing revenue disruption and providing the client with a more scalable subscription management platform.

Senior Full-Stack Software Engineer | 2021 to 2024

Full-Stack Software Engineer | 2018 to 2021

As a Full-Stack Software Engineer, I was responsible for developing and deploying cutting-edge solutions that drove merchant growth and expanded the company's global reach. My key contributions were focused on two major initiatives:

Merchant Re-engagement SDK: I was a core developer on a new privacy-centric Shopping SDK designed to combat customer drop-off. I engineered backend systems in Node.js that allowed merchants to re-engage specific user segments (e.g., cart abandoners, inactive customers) with targeted promotional offers. A primary architectural achievement was creating a system that delivered these offers without exposing the user's personal identity to the merchant, maintaining trust and compliance. This SDK provided a critical new marketing channel for thousands of merchants on the platform.
Braintree Global Payment Expansion: I played an integral role in Braintree's strategic expansion into emerging markets. I developed and implemented complex, scalable integrations with local Payment Service Providers (PSPs) across South America, Africa, and the Middle East. This involved architecting solutions to handle diverse third-party APIs, currencies, and regulatory requirements, ultimately unlocking new revenue streams and enabling payment processing in previously unsupported countries for the first time.
