Creating and deploying Go Services at scale

Working as a back end engineer for an auction platform for excess inventory liquidation . It was very instructive in terms of modern distributed system architectures and cloud computing.

Projects - Integration with leading retailers

Environment / Technologies: Go, RabbitMQ, Docker, GCP

As part of overall strategy to convert our monolith into microservices, we used the strangler pattern and picked off a discrete chunk to turn into a microservice

Inventory data and order status interchange was critically important and also demanded speed and persistence (which RabbitMQ provided seamlessly)

Containerization helped with tremendously with deployment and scaling

After our initial deployment , we successfully deployed to more clients with little intervention

As part of a team of 3 software engineers, I developed manufacturing automation software deployed in the factory for Apple TV, Apple Watch and iPad.

Coordinated development with Apple Engineers (electrical, mechanical & software); defined and implemented new architectures and protocols for manufacturing

Worked on-site to drive implementation at factory locations in Asia

Successfully scaled the automation from one prototype to many thousands of workcells. Apple also deployed this automation solution for manufacturing several other Apple products

Designed and implemented automation solutions for varied city infrastructure; Implemented and maintained systems and procedures to ensure that the City of Wooster stays compliant with Ohio State mandates & policies

Project: Automation for Bulk Water Filling Station

Environment/ Technologies: C, MySQL on Linux, and C# on Windows

I designed and ployed a cost-effective (<$15K) automation solution for the bulk water filling station after the city had spent over $150K unsuccessfully attempting to automate the control systems

Prototyped and implemented a pump controller running Linux on a custom PCB to convert 4-20V to RS232C; wrote C code to communicate with, and control the pump

Implemented smart-card based authentication mechanism to provide authorization for customers & integration with billing - delighting customers since this eliminated manual authorization by city employees

Implemented C# based front-end UI invoicing systems using a MySQL connector to cut down billing process from 1 week to 15 minutes

Project: Mandatory Compliance (various)

Environment & Technologies: Linux, PHP MySQL, Windows, MS SQL Server

Implemented multiple systems & software solutions to ensure that the city complied with Ohio State mandatory policies

Interviewed stakeholders, gathered requirements and implemented LAMP-based web applications that used Microsoft Active Directory for authentication and authorization

Ported / migrated legacy applications to Windows / MS SQL server

Resulted in the city saving several million dollars in regulatory fees
