At Personal Capital creating better financial lives through technology and people.
I have just joined the front end team and I’m loving it. The way we live in a startup pace, moving agile and collaborating every cycle surrounded by amazing people makes it perfect for professional development.
We have a great tech/skills stack and I wanted to share it with everybody especially those who are thinking in joining our team.
We believe in the power of technology to change the financial industry, making it more accessible, affordable, and honest. And we believe in the power of people to change the nature of investment advice, making it more transparent, objective, and personal.
Living in a world that is constantly talking about saving money and figuring out complex investment decisions, our front end engineers face a huge challenge: to make things as simple as one click.
To make that possible, we process lots of data. We utilize user information to generate what we call a progressive profile. Every user has a progressive profile which is generated from their individual inputs.
By doing this we can recommend plans, proposals and functionalities so our users can get the most out of our platform. This is how our award-winning platform allows 1.2 million users to track and invest their assets.
Ensuring that our technology operates on multiple devices is a must, not only a web platform, but within easy-to-use apps. Our users want access to their finances at home and on the go and that is what we deliver.
The Front-End Stack
This article will be cover our web platform tech stack, the one that we use day to day to make things as easy as one click/tap.
On development and build time we use Node.js, which we mix with some browser-sync flavor to proxy all non-static requests to a development server in the Amazon Cloud, Node and browser-sync serve the static resources to keep it simple. The team specifically chose not to use any build system like Gulp or Grunt to avoid having extra external dependencies.
Since the front-end layer is simple, NPM manages all the tasks.
Single Page Application
Our back-end services are written in Java, and we consume them using Backbone and Angular. This allows us to reuse tons of pre-implemented open source plug-ins and create reusable components that can be implemented across all of Personal Capital application’s domain.
Most of our platform is written using handlebars templates. This gives us the unique ability to use lots of pre-build helpers and accelerating the prototyping and development process.
We are migrating from Bootstrap to Inuit, refactoring code and creating our own styling framework based in OOCSS/BEM. By doing this we can ensure coding style consistency across our styles sheets, generating maintainable beautiful code that is reusable and easy to understand.
This is especially important since the company is growing rapidly, and by doing this we help our new engineers to jump in the train faster and deliver value sooner.
If you use our platform, you have seen a lot of beautiful visual components to our design. We use graphics whenever possible to make complex data easier to understand.
Our graphics manage complex datasets. They are dynamic so you can interact with them and get from the most generic information to the more specific transactional details.
To achieve this, we used Raphael. But as it is no longer being maintained, we are transitioning to D3 library, which is much more flexible and powerful, giving us the tools to generate almost any kind of graphics that we can think of.
Mocha, along with Chai (expect/should – BDD style) worked out well for us with a effective yet readable tests. I cannot emphasize the importance of readable tests enough. Now the feature set can be seen across the organization, comparing the expected outcome with the outcome. We’lI have to do a write up sharing more of our excitement.
The use of Mocha and Karma helped us on the path to continuous delivery and immediate regression reports. Tests are executed periodically by our continuous integration server, which monitors the health, watches for the codebase consistency and gives us the code coverage information. This is really important to ensure that we’re delivering a first class service/product.
Automation and CI
We use Jenkins as the orchestrator to build, test and deploy all of our environments. Our DevOps team wrote the tasks that run automatically or on-demand with one click.
Jenkins triggers Karma to run our Mocha test and Selenium to run-regression. Those tests are run in different browsers, the ones with head and without it (AKA headless browsers).
BTW, Karma watches our files and runs tests in development time too, eliminating the necessity of doing so before pushing code and giving us immediate feedback on what we are coding.
We also have integration with Husky that prevents our dev team from pushing code up to the origin/remote if there are failing unit tests.
We use Git and we love it. The workflow is pretty similar to git-flow. We just extend it, adding a few extra branches like a sandbox one, where we make al kinds of experiments.
Once we run “git push”, the linters and code style
At Personal Capital, everyone is a team player. We volunteer to get tasks assigned based on our expertise. We use scrum across all of the engineering teams and our sprints last one
We align our engineering efforts with our company’s mission: Better financial lives, through technology and people.
Just like our financial advisors abide by the fiduciary standard (meaning financial advice they give must be in the best interest of our clients), we develop products and services that serve the best interests of our users and clients.
We create new business opportunities by tackling complex financial problems facing millions of American families.
Every day we create a more connected and data-driven financial ecosystem for our users.
We take pride in our intuitive user experiences and a high quality of service that delights our users.
We filter out the noise to surface the most important information via data visualizations that show how financial actions create a storyline our users can follow to understand their current and future net worth.
We empower our users with personalized financial planning tools.
We believe the best solutions come from empowered cross-functional teams of engineering, product, marketing and advisory, and we believe in the spirit of collaboration.
We believe an important way to deliver financial advice is through data visualization and intuitive user interfaces.
We believe everything we do should be measurable,transparent and accessible to all.
We value open and streamlined communication from documentation in code, automated tests and captured product discussion; we speak our minds openly and freely.
We believe quality is everyone’s concern, and together we work hard to create a product that will improve people’s lives.
We embed best security practices in everything we do, at every level of our organization.
We value accountability, with the goal of fostering leadership and focus.
We work smarter, not harder: we use data to create and refine our business rules to get better results and use automation to scale them.
We promote our processes and best practices by automating them.
We let our code speak for itself through documentation, unit tests and test cases.
At Personal Capital, we’re all about changing the face of financial technology, and we are always looking for great talents to join our team. And you will join a team that works together to motivate, inspire, and change an industry.
This blog post would be better suited if I wrote it in the beginning of the summer but whoops. I’ve been working full-time at Personal Capital for over two months now. Last summer I interned here and in this post I’d like to share to all current and future interns some tips to maximize their internship experience.
1- This is your time to shine. Show them what you got!
Congrats! You made it past the interviews, offered an internship, and now spending the next couple of months working for them. This is an audition for both sides. They’re trying to further evaluate your skills and how you interact with others. From your perspective you want to see if this is a company that you see yourself working for after college.
2- Always be eager to learn and ask how to improve.
You’re probably the youngest person in the company. You’re surrounded by people with years of experience who have been through a lot. You can learn so much from them! Also soliciting feedback on the work you’re doing is very helpful in developing you, the professional.
3- Seek out help if you need it.
If you’re stuck on something or just don’t understand the task/problem at hand be sure to ask questions. There’s no such thing as asking too many questions. You might spend a lot of time on something that was not needed or wrong. I’m sure your supervisor would rather take a little time in the beginning to ensure you don’t spend unnecessary time down the road.
4- Dabble in different things.
This is your opportunity to try out something you don’t really know about. Some companies will differ in how much you can explore outside what you’re brought into do, so your mileage may vary on this one. Every company has many projects happening or want to happen, and this is your chance to see if it’s what your passionate about.
5- Go out to lunch.
You’re surrounded by many fascinating people, all with different backgrounds and journeys they took to get where they are today. Unfortunately in the office we’re just so focused on the task at hand that we really don’t get to know the people we work with. Grabbing lunch is an excellent opportunity to really get to know about them. Be it one-on-one or a group; I know I really enjoyed “Lunch Crew” when I was an intern.
6- If you’re interested in returning, let them know!
Lastly if you are interested in working there in the future, communicate that towards the end of your internship. After having a great time last summer I spoke with our Ehsan, our VP of Engineering, and was fortunate to be offered a full-time position after graduating. I’m not alone. According to the National Association of Colleges and Employers (NACE) 2015 survey, employers converted 51.7 percent of their interns into full-time hires. You can be a part of the majority!
That’s it! I hope you enjoyed this post and find it useful!!
