About Me

I like to hang out at the bleeding edge of open source and big data.

Day to day, I'm the founder/CEO of fineo.io.

In my freetime I'm also an Ironman triathlete, yogi, foodie and amateur board game maker.

  • 05 Jun 2017 » Hard isn't Valuable: Looking back on Fineo

    I’ve decided its time to wrap up Fineo. I took a shot for a while (nearly two years!), but I’m way past my original time deadline to get traction and well out of (allocated) money. I’ve spent the last few weeks writing up some of the interesting architecture/design work I did, so at leas...(read more)

  • 22 May 2017 » Building Up Fineo's Continuous Integration with Jenkins

    Getting a robust continuous-integration (CI) suite was an early priority at Fineo. By spending some upfront time getting good infrastructure in place we could move dramatically faster down the road; with a distributed, micro/nano-service based architecture, in-depth testing across the stack is a ...(read more)

  • 18 May 2017 » Interlude: Self-Improving Architecture and Design

    A short break from the Fineo architecture. Recently get for the thinking about self-improving systems. Specifically, I liked the idea of a self-improving system where the actors in and around the system are incentivized to continually improve the system. This makes sense in context of a ...(read more)

  • 17 May 2017 » Handling Errors in Fineo

    Passing pipeline processing errors back to the user was not originally built into the Fineo platform (a big oversight). However, we managed to add support for it over only a couple of weeks. Moreover, we were able to make it feel basically seamless with the existing platform. (read more)

  • 15 May 2017 » Supporting Schema Evolution and Addition in Fineo

    Fineo’s architecture is designed to help people go faster, while having to do less by leveraging our NextSQL system. At the surface, it’s not that much different from the the Lambda Architecture - a realtime serving layer and an offline batch processi...(read more)

  • 12 May 2017 » Scaling Out Fineo

    A deeper look into how Fineo manages its seamless scalability across the multi-layer architecture. By enabling each layer to scale independently and leaning on existing, fully-managed services we can enable wildly scalable infrastructure without notably increasing operations effort (and often dec...(read more)

  • 10 May 2017 » Using DynamoDB for Time Series Data

    Time is the major component of IoT data storage. You have to be able to quickly traverse time when doing any useful operation on IoT data (in essence, IoT data is just a bunch of events over time). (read more)

  • 08 May 2017 » Multi-tenant SQL Security In-Depth

    Multi-tenancy is an abstraction for a big, hard group of problems that touches on security, scalability, resource consumption and quality of service. Generally attempting to back-fit multi-tenancy is, at best, hacky and less than satisfying; at worst, its a recipe for disaster. (read more)

  • 05 May 2017 » Translating SQL queries for schema on NoSQL

    Fineo uses a novel semi-schemaful approach to unlock the potential of NoSQL data stores, while simultaneously enabling ‘metalytics’ queries by providing an engine that seamlessly supports everything from nearline, operational queries (e.g. low latency, small scale) to deep, ad-hoc analytics. Prim...(read more)

  • 02 May 2017 » Implementing Dynamic Schema At Scale

    Rehash of the Dynamic Schema at Scale for how we implemented reading semi-schematized data from a NoSQL. I touch on the query translation and processing of updating schema. (read more)

  • 01 May 2017 » Scaling up for an IoT World

    With Fineo’s Beta availability (link), I thought it would be interesting to look at how Fineo actually supports IoT-scale ingest and eliminates the need for traditional pipelines and the mainta...(read more)

  • 27 Apr 2017 » An investment thesis

    What’s new and interesting? What’s worth focusing on? Its worth taking a step back and looking at the larger picture. It helps make sure you are doing the right thing, for the right reasons. Doing that every day means nothing gets done, but too infrequently means getting lost in the weeds and, pe...(read more)

    For years, hobbyist having been hacking their homes to create smarter parts that respond to their every whim. Smart homes were thrust even further into the public concience with the first Iron Man (2008) movie. Suddenly, everyone wanted self tinting, weather informing windows or a home assistant ...(read more)

  • 09 Mar 2016 » Dynamic, Lazy Schema at Scale

    Schema management is some of the most painful database work and anything you can do to make it easier can dramatically reduce an enterprises’ iteration interval. At Fineo we are focused on delivering a scalable, enterprise grade time-series platform. While we do lot...(read more)

    I’d like to talk a bit about the AWS-focused ingest pipeline that we developed at Fineo. Not too ironically, its very similar to the pipeline that Netflix discussed by in a recent ...(read more)

  • 26 Oct 2015 » Choosing Hadoop Deployment tooling

    Picking the right tools for deployment can be tricky and have long-lasting effects on your organization. Over at Fineo we have the luxury of doing everything from scratch. This means no concern with legacy tools, monitoring, or just cruft. Instead, we have the op...(read more)

  • 17 Aug 2015 » Using Maven Shade to Run Multiple Versions in a JVM

    Sometimes, you will want to run multiple versions of the same library in the same JVM. Maybe you are writing a framework to run arbitrary user code or maybe you are just integrating with legacy code; either way, you will need a way to run both versions of some library in the same JVM - enter the ...(read more)

    Secondary indexing for HBase is a difficult problem, but remains perennially popular. Various implementations exist, but all fall short either in features or latency. [Phoenix](http://www.github.com/forcedotcom/phoenix) is soon gaining support for what we consider "HBase Consistent" Secondary ind...(read more)
