Why I Belong at Twilio
Imagine all of the different people that might speak to a business, all of the different reasons they might do so, all of the different channels they might use, and all of the different experiences they need to have when they get in touch.
Now imagine building a future of communication that enables businesses to respond to all of those needs, in all of those different moments; to deliver experiences that aren’t just good enough, but are brand-enhancing and loyalty-inducing.
To do so, you need engineering skill and technical ability. But you also need imagination and empathy. You need people who can understand each of your customers and each of your customers’ customers and help every organisation find a way to deliver experiences that make a difference. You need people who can help other people imagine what’s possible, in order to help make it possible.
Well, that’s ...
Twilio SendGrid Day One: Building My Track Jacket App
From the beginning, Twilio and SendGrid have both enshrined customer experience in their core values. SendGrid strives to be Humble and exemplify a customer-first mindset. Twilio encourages employees to Wear the customer’s shoes.
We live those values everyday. There’s a hallowed tradition here at Twilio: every Twilion who builds and demos a Twilio powered app earns their red track jacket. Working on an application from a customer’s perspective helps us truly build empathy for our users.
Today, as Twilio and SendGrid celebrated coming together as one company, I had the opportunity to demo my track jacket app. Using building blocks from Twilio and SendGrid I built an SMS responder which also emails a GIF using Python and the microframework Flask.
Let’s look at how it works so you can build your own.
Prerequisites for my SMS and Email Responder
To reproduce my code you’ll first ...
Introducing Twilio Community Developer Michelle Glauser
Becoming a software engineer in 2012 not only introduced me to work that would always be interesting, it also tripled my income. That was really empowering.
My new career came with a cold dose of reality, however—there wasn’t really any kind of diversity represented in the technical teams I saw. As I thought about why that was, I wondered why no one had ever pointed out that I might be interested in software engineering. After all, I was the only girl I knew or member of my family who’d taught myself to navigate DOS as an 8-year-old and memorized all the WordPerfect commands. The first time I accessed the internet, I spent hours looking up topics that interested me at the time—mostly Tamagotchis. I picked up some Visual Basic 6 in the .Exe Filers computer club at school, snuck Juno dial-up onto the family computer, and ...
Diversity & Inclusion: A Sense of Belonging At Twilio
Twilio is changing how people feel about going to work and is well on its way to becoming a prime example of a workplace where people can do the best work of their careers, and where diverse talent is not only sought after, it’s embraced and nurtured.
The company has taken its workplace diversity and inclusion commitment a step further by setting some ambitious goals around recruiting, equitable pay and promotions, and cultivating a company-wide sense of belonging. In fact, when Twilio celebrates its 15th anniversary in 2023, it's aiming for every Twilion to feel that they belong.
Twilio believes that having a diverse workforce brings unique ideas to new prototypes. And when employees feel included, not only will exceptional talent come to the company, they’ll be happier and stay longer. “You can spend a lot of money on just recruiting and bringing people through the door; but ...
Introducing PHP Developer Marcus Battle
The house lights darkened. Drums began to play from backstage. Strings warmed up the orchestra pit. Suddenly there were the words I had secretly been waiting for. The ones that the average American still gets wrong twenty years later, but loves to unashamedly sing. "Nants ingonyama bagithi Baba." The introduction to the “Circle of Life” was ringing throughout the auditorium.
I found myself in a parade of 750 pounds of silicone rubber fashioned into Zulu costumes, 18-foot giraffes, flocks of birds in the mezzanine and 6-foot elephants walking through the aisles. The entire auditorium became the stage. The floor opened up to expose Pride Rock and Simba's dedication. My inner child awoke. I completely gave in to experiencing "The Lion King" on Broadway.
“Dad, don’t we eat the antelope?
Yes, Simba. But let me explain.
When we die, our bodies become the grass.
The antelopes eat the grass ...
Abstraction and Orchestration — How We Built the Twilio API for WhatsApp
Businesses want to be where their customers are and popular messaging apps are those places today. Facebook Messenger, WeChat, LINE, Viber and other popular messaging apps have already rolled out APIs that businesses can use today. But until very recently, there was one notable holdout—WhatsApp.
More than 1.5 billion people globally use WhatsApp everyday to talk to friends and family as well as for work and collaboration, and in August this year WhatsApp launched the highly anticipated WhatsApp Business API. Businesses have been clamoring for an officially supported way to communicate with WhatsApp users for years now. The excitement is more than justified.
WhatsApp is a unique messaging platform with end-to-end encryption between clients. Central servers ...
Cloud Orchestration, Lazarus and Interning at Twilio
There are a few technical interview strategies everyone knows: communicate your thoughts, give yourself time to think, and keep calm. Absent among these, of course, is coming up entirely blank for a question. So when in the interview for an engineering internship my manager asked, “What experience do you have with distributed systems?” I took a deep breath and, cringing a little, replied, “None, yet. But I’m smart and I learn fast, and I’m interested to learn by working in one.” This was true. I’d been curious about the subject for a while, and figuring it wouldn’t hurt to try, had worked up the courage to apply to a role for which I didn’t hit every “ideal qualification” checkbox. (Take that, tech gender gap!) And to my surprise and relief, I moved forward – all the way to San Francisco, to a spot on Twilio’s ...
Introducing Twilio Developer Evangelist Layla Porter
I had drifted through a broad variety of careers from Retail to Marketing, Professional Rider to Personal Trainer but never quite found the right fit for me. Yet the moment I decided to change career from Pilates teacher to software engineer I knew it was the right decision.
A little bit of context
My father passed away suddenly in 2013 and I was faced with the realisation that life is too short to traverse without purpose.
This caused my whole outlook on life to change, I became more daring and confident whilst becoming more analytical about my own situations.
At the time of my dad’s passing I’d been running a successful Pilates studio from a shed in a friend’s back garden. It could accommodate just four people in each class so with my new-found bravery I seized an opportunity to use my savings and open commercial premises ...
8 Ways Personal Information Is Like Uranium
Want to Be A More Privacy-Aware Developer for Data Privacy Day? Think of Personal Information like Uranium
Sunday, January 28th is Data Privacy Day. And, I know the best way for Twilio to celebrate the day would be with a post on best practices for handling nuclear reactor fuel. Kidding. In all seriousness, much of Data Privacy Day is focused on building awareness among consumers about how they can protect their privacy on the internet – a noble cause. But what about a little awareness-building for you, the developers – the doers that build that internet?
Now, I’m no nuclear physicist, but I am Twilio’s Associate General Counsel and head up our privacy program. So, let me plead my case that if you want to become a more privacy-aware developer (and who doesn’t?!), one way to get into the right frame of mind is to think of handling personal ...
Chaos Engineering at Twilio with Ratequeue HA
Twilio engineers are constantly working on improving our core services to meet or exceed 5 nines of availability. A system’s capacity for self-healing when a fault occurs is a key measure of achieving high availability. Recently, Twilio used Chaos Engineering to close the gap and eliminate the need for human intervention for common faults involving our core queueing-and-rate-limiting system, Ratequeue.
Twilio empowers customers to make 100’s of concurrent API requests. However, your messages may be unexpectedly rate-limited, such as carrier regulations (US long codes), contractual limitations (US short codes), or technological (e.g. capacity). As a safeguard, Twilio automatically queues outbound messages for delivery. Each Twilio phone number gets a separate queue and messages are dequeued at rate depending on the contract.
Ratequeue is an internally-developed distributed queueing system designed for simultaneously rate-limiting dequeue rates for many ephemeral queues. Each sender ID (e.g. phone number ...
