Sagas with Step Functions

Video. In distributed systems, business transactions spanning multiple services require a mechanism to ensure data consistency across services. The Saga pattern is a pattern for managing failures, where each action has a compensating action for rollback. In this talk, learn how you can use AWS Step Functions to create state machines for your Lambda functions and apply the saga pattern to serverless.

Building Scalable Applications with the Serverless Framework and AWS Lambda

Get the Book. Video. Serverless is a hot topic in the software architecture world. A serverless architecture approach replaces long-running virtual machines with ephemeral compute power that comes into existence on request and disappears immediately after use. Pay for the hamburger, not the cow!

React Made Easy and Simple with Next.js

It’s not a secret that creating client-side JavaScript is pretty difficult these days. Next.js is a minimalistic framework for server-rendered React applications with zero setup and simple deployment!

Writing and Publishing Elixir Libraries

In this talk, we’ll walk through the process of writing and publishing an Elixir library from scratch. Along the way, we’ll discover a handful of Elixir features such as: Mix, Documentation, Doctests, Typespecs, and Hex.

Event-Driven APIs with Webhooks

Arrr! The concept of a Webhook is simple. Webhooks are a way to receive valuable information when it happens, rather than continually polling for that data and receiving nothing valuable most of the time. In this talk, discover the wonderful world of webhooks, real-life applications, and best practices.

Beyond JSON: Alternative Data Serialization Formats

Today, JSON (Javascript Object Notation) is the de-facto serialization format for exchanging data between HTTP-connected services. Several features of JSON makes it a useful general purpose format: it’s human readable, easy to learn, and the ubiquity of Javascript. In this talk, let’s look beyond JSON. We’ll learn about three different serialization formats (MessagePack, Protocol Buffers, and Apache Avro); and discover a range of benefits unique to each.

GraphQL in an Age of REST

Video. GraphQL is an application layer query language from Facebook. With GraphQL, you can define your backend as a well-defined graph-based schema. Then client applications can query your dataset as they are needed. GraphQL’s power comes from a simple idea — instead of defining the structure of responses on the server, the flexibility is given to the client. In this talk, discover a new approach to build and expose Web APIs. Will GraphQL do to REST what REST did to SOAP?

Entity Component Systems in Elixir

Entity-Component-System (ECS) is a distributed and compositional architectural design pattern that is mostly used in game development. Elixir is a dynamic, functional language built on top of the Erlang VM designed for building scalable and maintainable applications. In this talk, discover how we can use both ECS and Elixir in a novel approach to structure our programs beyond the traditional OO/inheritance paradigm.

2014

A Gentle Introduction to Web Map APIs

Lead and taught a technical workshop on Web Map APIs and how to build map-intensive applications such as Airbnb and Foursquare using OpenStreetMap, Mapbox, and Leaflet. Also covers “slippy” maps, tileservers, and geocoding.
