The MongoDB Summer ‘18 Intern Series: From Hackathon to Haskell
Mihai Andrei is going into his senior year at Rutgers University, the alma mater of MongoDB CEO Dev Ittycheria. While Dev received his BS in Electrical Engineering, Mihai is studying Computer Science and minoring in Mathematics. Mihai is also extremely involved in HackRU, a 24 hour student run hackathon at Rutgers. Andrea Dooley : Hackathons are very popular amongst CS students. What roles have you played for Rutgers HackRU? Mihai Andrei : If you are an organizer you’re not able to participate in the event, but this coming year I will be one of two Executive Directors, essentially overseeing the entire thing. In the past I have played the part of Director of Finance for the event, so I know this will be a particularly challenging role, but nonetheless an exciting one. AD : You’ve been involved with HackRU for quite a while. Is that where you first learned about MongoDB? MA : I actually learned about MongoDB during a student demo at a tech talk on campus. The first time I ever used MongoDB was at a previous internship for a data warehouse application we were developing. I was looking online for internship opportunities in the software industry and came across an opening for the MongoDB internship program. AD : What made you interested in interning at MongoDB? MA : My previous experience interning has mostly been with financial institutions, so this time around I wanted to take a different route to a company with more emphasis on tech and tech culture. I was able to get a good sense of the culture during the recruiting process, so I was really excited when I got the offer. AD : Did you know our CEO was a Rutgers alum? MA : I learned that Dev attended Rutgers a bit later on, but I think it’s really cool that someone from my university became the CEO of such an awesome company. AD : What MongoDB Eng team are you on, and what projects were you responsible for this summer? MA : I’m on the query team working on the MQL model, which is a model implementation of the query language built from scratch, serving as a reference. The reason for creating it from scratch is to identify flaws and iron out changes for future implementations, and the model can be a point of reference for how we create future versions of the query language. There are some flaws in the current version of the language that need sorting out for future iterations. AD : What were some of the flaws present in the query language? MA : An example of a flaw in the query language is the difference between find and aggregation projection. They are ambiguous and one will allow you do things the other doesn’t. For example, in aggregation you are able to use nested documents to specify how to project your output. That is not possible in find, but in find you have special operators to customize an output for arrays such as $elemMatch that you can’t use in aggregation projection. The ultimate goal is to unify the semantics. AD : Did you have any previous experience working to improve a programming language, or did you find there was a learning curve? MA : I took a programming languages class last year so I was able to learn about what goes into creating a programming language. I spent my first few weeks at MongoDB learning Haskell. I had to sit down with other team members to go through the code base and get ramped up. It’s been very rewarding from an educational and experience standpoint. AD : What would you say is one key takeaway from your experience at MongoDB this summer? MA : Beyond learning a new programming language and what goes into writing the MongoDB query language, what I wanted to get out of my summer internship was to learn how to develop software more collaboratively. MongoDB has a code review process, so you’re given a ticket but just completing the ticket is not enough. You have to run it by other members of the team to ensure it meets expectations. There’s been really great quality control feedback from the team. AD : How has the level of feedback helped to benefit you as an engineer early in your career? MA : Every week I sit down with my mentor for a thirty minute one on one to discuss how things are going. The continuous feedback has been very helpful because it helped me to improve the quality of the comments I left in my code. It was easy for me to understand what I did and how I did it, but I learned that you need to be very thorough in order for other people to understand as well. AD : What would you say to someone considering an internship opportunity at MongoDB? MA : I would absolutely recommend it. It’s a great environment to intern in, and I have really been able to grow my skills. The work is very challenging, but very rewarding, and I understand exactly how my project is going to impact the work my mentor and other members of the query team will continue doing after I leave.

Australian Start-Up Ynomia Is Building an IoT Platform to Transform the Construction Industry and its Hostile Environments
The trillion dollar construction industry has not yet experienced the same revolution in technology you might have expected. Low levels of R&D and difficult working environments have led to a lack of innovation and fundamental improvements have been slow. But one Australian start-up is changing that by building an Internet of Things (IoT) platform to harness construction and jobsite data in real time. “Productivity in construction is down there with hunting and fishing as one of the least productive industries per capita in the entire world. It's a space that's ripe for people to come in and really help,” explains Rob Postill , CTO at Ynomia. Ynomia has already been closely involved with many prestigious construction projects, including the residential N06 development in London’s famous 2012 Olympic Village. It was also integral to the construction of the Victoria University Tower in Australia. Link to Podcast Episode Here “These projects involve massive outflow of money: think about glass facades on modern buildings, which can represent 20-30 percent of the overall project cost. They are largely produced in China and can take 12 weeks to get here,” says Postill. “Meanwhile, the plasterer, the plumber, the electrician are all waiting for those glass facades to be put on so it is safe for them to work. If you get it wrong, you can go in the deep red very quickly.” To tackle these longstanding challenges, Ynomia aims to address the lack of connectivity, transparency and data management on construction sites, which has traditionally resulted in the inefficient use of critical personnel, equipment and materials; compressed timelines; and unpredictable cash flows. To optimize productivity, Ynomia offers a simple end-to-end technology solution that creates a Connected Jobsite. Helping teams manage materials, tools, and people across the worksite in real time. IOT in a Hostile Environment The deployment of technology in construction is often fraught with risk. As a result, construction sites are still largely run on paper, such as blueprints, diagrams and models as well as the more traditional invoices and filing. At the same time, there is a constant need to track progress and monitor massive volumes of information across the entire supply chain. Engineers, builders, electricians, plumbers, and all the other associated professionals need to know what they need to do, where they need to be, and when they need to start. “The environment is hostile to technology like GPS, computers, and mobile phone reception because you have a lot of Faraday cages and lots of water and dust,” explains Postill. “You can't have somebody wandering around a construction site with a laptop; it'll get trashed pretty quickly." Enter MongoDB Atlas “On a site, you might be talking about materials, then if you add to that plant & equipment, or bins, or tools etc, you're rapidly getting into thousands and thousands of tags, talking all the time, every day,” said Postill. That means thousands of tags now send millions of readings on Ynomia building sites around the world. All these IoT data packets must be stored efficiently and accurately so Ynomia can reassemble the history of what has happened and track tagged inventory, personnel, and vehicles around the site. Many of the tag events are also safety critical so accuracy is a vital component and packets can't be missed. To address these needs Ynomia was looking for a database that was scalable, flexible, resilient and could easily handle a wide variety of fast-changing sensor data captured from multiple devices. The final component Postill was looking for in a database layer was freedom: a database that didn't lock them into a single cloud platform as they were still in the early stages of assessing cloud partners. The Commonwealth Scientific and Industrial Research Organisation , which Postill had worked with in the past, suggested MongoDB , a general purpose, document-based database built for modern applications. “The most important factor was that the database is event-driven, which I knew would be difficult in the traditional relational model. We deal with millions of tag readings a day, which is a massive wall of data,” said Postill. A Cloud Database Ynomia is using MongoDB Atlas , the global cloud database service, now hosted on Microsoft Azure. Atlas offers best-in-class automation and proven practices that combine availability, scalability, and compliance with the most demanding data security and privacy standards. “When we started we didn't know enough about the problem and we didn't want to be constrained," explained Postill. "MongoDB Atlas gives us a cloud environment that moves with us. It allows us to understand what is happening and make changes to the architecture as we go." Postill says this combination of flexibility and management tooling also allows his developers to focus on business value not undifferentiated code. One example Postill gave was cluster administration: "Cluster administration for a start-up like us is wasted work," he said. "We’re not solving the customer's problem. We're not moving anything on. We’re focusing on the wrong thing. For us to be able to just make that problem go away is huge. Why wouldn’t you?" Atlas also gives Ynomia the option to spin out new clusters seamlessly anywhere in the world. This allows customers to keep data local to their construction site, improving latency and helping solve for regional data regulations. Real Time Analytics The company has also deployed MongoDB Charts, which takes this live data and automatically provides a real time view. Charts is the fastest and easiest way to visualize event data directly from MongoDB in order to act instantly and decisively based on the real-time insights generated by event-driven architecture. It allows Ynomia to share dashboards so all the right people can see what they need to and can collaborate accordingly. “Charts enables us to quickly visualize information without having to build more expensive tools, both internally and externally, to examine our data,” comments Postill. “As a startup, we go through this journey of: what are we doing and how are we doing it? There's a lot of stuff we are finding out along the way on how we slice and re-slice our data using Charts.” A Platform for Future Growth Ynomia is targeting a huge market and is set for ambitious growth in the coming years. How the platform, and its underlying architecture, can continue to scale and evolve will be crucial to enabling that business growth. “We do anything we can to keep things simple,” concluded Postill. “We pick technology partners that save us from spending time we shouldn't spend so we can solve real problems. We pick technologies that roll with the punches and that's MongoDB.” When we started we didn't know enough about the problem and we didn't want to be constrained," explained Postill. "MongoDB Atlas gives us a cloud environment that moves with us. It allows us to understand what is happening and make changes to the architecture as we go. Rob Postill, CTO, Ynomia
