Work Experience

I have eclectic interests which have led me to work in various industries in varying roles. I have been a project manager, a software developer, an engineering consultant, a technical salesman, and also dabbled in marketing. My resume already lists the various positions; on this page I will elaborate on some of them (in no particular order). 

Amazon Web Services

Amazon Web Services (AWS) is a subsidiary of Amazon which provides on-demand cloud computing services. Various companies run part or all of their systems on the AWS cloud. For instance, Netflix uses AWS for most of its computing and storage needs, which includes databases, analytics, recommendation engines, and video transcoding. To  provide these cloud services Amazon builds and maintains massive data centers in multiple regions around the world. I worked in the org that builds and operates the datacenters and was a project manager in charge of R&D projects for developing and testing new technologies to improve the operations.

One of the goals of my projects was to make the datacenters more efficient. Datacenters consume a significant amount of power for cooling and my projects revolved around deploying sensors, observing trends, and building smarter control systems to optimize cooling. Another goal was to make the company less reliant on external vendors who use locked-down proprietary operating systems that make it harder to innovation internally. To this end we designed and programmed electrical devices (such as PLCs) and sensors for internal use and built test environments to experiment with them.

The teams I managed were spread across the United States and consisted of professionals in various fields including controls engineers, software developers, systems developers, data scientists, and machine learning specialists, and my primary task was to ensure the projects stayed on track and sound technical decisions were being made. I was also responsible for all administrative and regulatory tasks related to the projects, such as working with the finance department to allocate funding, interfacing with environmental teams to ensure we meet regulations, working with legal counsel to make sure we have the right licenses, negotiating with vendors to supply parts, coordinating efforts with the security teams to build safe products from ground up, interacting with compliance teams to get the necessary certifications, and so on.

Dassault Systèmes Simulia Corp.

Dassault Systèmes is a French company that makes computer-aided design (CAD) software and product lifecycle management (PLM) software. I worked for the Simulia brand of the company, which develops the Abaqus finite-element analysis software and the Isight workflow optimization software. 

I initially started at Simulia as an business development intern in their academics department, where I helped with marketing and selling the product to academic institutions and academic researchers. I worked with prospective academic customers to demonstrate the capabilities Abaqus in relation to their research projects, and help new academic customers adopt of the software. As an example, I helped a biomedical researcher bring a 3D scan of a spinal vertebra into Abaqus as an STL file.

I also created case studies with existing academic customers for marketing purposes. A particularly interesting one was a case study I did on the recovery and conservation of the H.L. Hunley, a Civil War era submarine that was the first combat submarine to sink a warship, after which it too sank off the coast of Charleston, South Carolina. I conducted a webinar with Dr. Vincent Blouin whose students were using Abaqus to simulate the stresses on the hull due to the slings which were used to hoist the submarine out of the water and also to hold it in place as part of the display.

I created and maintained a database of worldwide Biotech and Bioengineering conferences which the company might consider attending or sponsoring, to educate biotech professionals that finite-element simulations are a good technique to gain insight into biological structures. I also provided imagery and technical input to help the graphics designers develop posters and fliers for these conferences. 

When the company launched their online learning community in 2010, I created a video training series for the Abaqus and Isight products. The tutorials were intended for engineers, researchers and students with little or no prior Abaqus experience, to bring them up to speed within a short amount of time. The series can be found here (requires login). 

After graduating in 2012, I joined the company full-time as a technical consultant and sales specialist. In this role I worked with Simulia clients in various ways:

  • I collaborated with them on consulting projects where I performed simulations or optimization studies for them, or wrote custom software tools to address their specific design challenges
  • I provided technical support to help them better use the product and overcome any simulation challenges
  • I instructed multi-day training courses on simulation concepts, optimization, and Python programming
  • I partnered with our sales representatives to showcase the benefits of using our technologies to potential clients

Altogether I worked with around 80 different engineering companies across a ranging of industries, including big names like General Motors, Goodyear, Apple, Nasa, and SpaceX, as well as smaller engineering firms and local manufacturers.
