Junior Full Stack Web Developer recently graduated from New Vision Foundation bootcamp.

I’m a junior full stack developer with a strong focus on Ruby on Rails and front-end design. My journey into software development started with a personal desire to create tools that simplify people’s lives — from project management apps to full client websites. What began as curiosity quickly became a passion, and today I’m building full-stack web applications with real-world API integrations, OAuth authentication, PostgreSQL databases, Docker, and clean, mobile-responsive front-end design. Recently, I completed an apprenticeship where I worked on a nonprofit SaaS platform alongside a professional engineering team. There, I deepened my experience with Rails 7, complex database migrations, OAuth token management, Docker containers, and production deployment processes. I also contributed to front-end UI improvements using Bootstrap, Tailwind, and Figma wireframes to enhance usability. I take pride in my ability to bridge the gap between back-end logic and polished front-end design. My previous background in customer-facing roles taught me how to listen carefully to user needs, communicate clearly, and collaborate smoothly on a team. I'm especially passionate about building intuitive, well-organized, user-friendly applications that feel good to use — and that scale with the needs of real people. I love the balance of structure and creativity that Rails offers, and I'm excited to continue building meaningful tools that make people's lives easier. Whether it’s integrating APIs, refining complex forms, or making sure a UI flows naturally, I enjoy solving problems and learning fast. If you're looking for a junior developer who’s reliable, coachable, eager to contribute, and can deliver polished features from database to browser — I’d love to connect!

Senior/Lead Eng/Co-Founder: Deep rails experience that comes with empathy, humor, and a bit of chaos

Seasoned code wrangler with over a decade in Ruby on Rails and a past life as a social worker and policy researcher. I've got a knack for translating geek speak for humans and wrangling stakeholder needs into delighted users and maintainable code. Looking to land in a place where code meets impact. Full stack developer that has spent over a decade in the Ruby/Rails ecosystem. I lean ops to backend, but I can get in there and wrangle JS components and CSS if need be. I often wear at least a little bit of a product manager hat, have been a team lead on large projects, and I even try to remember to write documentation and technical briefs. I'm longwinded in slack, shy in person, didactic and friendly in code reviews, and occasionally down a rabbithole. Loves: Wrangling weird bugs and annoying APIs, refactoring, clear code (for the humans) and good tests (for the robots), figuring out the best places to deliver maximum impact and shipping quickly, teaching myself new things, compassionate communication and collaboration with multiple stockholders, making weird things happen in the CI pipeline Special superpowers: T-shaped generalist that still geeks out on learning new things, sniffing out something that isn't a problem yet but definitely will be (and I don't mean premature optimization), care a lot about readable code. Worked as a social worker for a decade, there's more soft skills than people might think in getting software out the door. Not so loves: JS in general, jerks, arrogance, watching junior developers not get the support they need and thinking it is their fault, refreshing staging for an hour wondering why my debugger isn't getting hit. -- Have worked in startups at all stages of their life cycle as both an introverted grumpy solo developer and team leader, helped make product decisions, mentored other developers, deleted prod a few times, etc. I chafe a bit at schedules, but occasionally I'll figure out a big that would have been a big problem in the future at 3am and just fix it. Love fixing those things. I can meeting during normal human hours though. -- Open to short and long term contracts and FTE for the right fit. Prefer chill flat organizations where everyone likes and respects each other and just gets stuff done. I've shipped features faster at those organizations than any that were focused on relentless hustle. -- Tell me why you believe in your tech and I'll tell you about one of my weird side projects like a Led Zeppelin button or a confessional that floats in the air. -- Have PhD level statistics classes buried in my brain somewhere, know my way around python and some data analysis, have built ETL pipelines - if it has to be done, I'll try to figure out a way to get it done. And the longer you hang around this world, you realize the most important programming language is being able to talk to people in kind and useful ways. -- Senior enough to know that sometimes it's the code you don't write that solves the problem ;) Junior enough to still get excited every time I make LEDs blink with magic words.

Hi! I'm Liz 👋🏼 I'm about as full-stack 🥞 as they come. I started as a QA and automation engineer and now I'm a senior full-stack engineer focusing on Rails and React. Early on as a QA I worked on projects from writing SQL scripts to check data, to automation engineering, to React Native applications, and even helping implement Kafka instances and a team transition to Kubernetes. Then I moved on to development, mostly focusing on Rails / React stacks. I also am very comfortable working in Python. Now I've been a full stack developer for a few years, always carrying my QA mindset with me. I love exploring the ins and outs of a problem, and figuring out where I can pick it apart and expose weaknesses. I'm really great at building relationships with stakeholders, establishing trust and cooperation so that we can all move forward with a project in a very pragmatic way. Pairing with coworkers is always very enjoyable for me. I like the collaboration, but I really value the mentorship the most. Teaching juniors git has become a mainstay for me, as well as coaching them to maintain a calm mindset while debugging, encouraging them to move through issues in a systematic way. And of course I always fit in robust testing, showing folks how to create test suites and pipeline automation that will improve their workflow. Let's talk about how I can contribute to your team and stack 🙌🏻

As a developer, my journey started with a curiosity for problem-solving and quickly turned into a passion for crafting elegant, maintainable code. My self-taught roots pushed me to dive deep into both the Ruby and JavaScript ecosystems, which has shaped me into a versatile engineer capable of handling both backend and frontend challenges. This adaptability has allowed me to thrive in complex, dynamic environments, often taking ownership of mission-critical projects that require innovative solutions and leadership. One of my proudest milestones was during my time at Salesloft, where I worked on a project to implement a bulk reschedule action for tasks in a dashboard used by sellers. The dashboard required real-time updates to ensure a smooth user experience, and the system had to handle thousands of tasks efficiently. To solve this, I created a Rails API that processed task IDs in batches using Sidekiq. Each task was passed to a service responsible for updating due dates, while Kafka was used to send updates back to the frontend. I built a component in the frontend that subscribed to Kafka events, ensuring that only the affected tasks were updated, thus minimizing API requests and enhancing performance. This approach preserved the user experience while significantly improving efficiency and scalability. What truly drives me is the opportunity to create software that has a real impact, whether it's streamlining processes, building tools that empower users, or mentoring others to reach their potential. I believe my strength lies in my ability to see the big picture, anticipate challenges, and proactively design solutions that are both scalable and maintainable. I don’t just focus on delivering code, I focus on delivering value. My combination of deep technical expertise, strong communication skills, and passion for problem solving means I can help bridge the gap between development teams and business goals, ensuring that technical solutions align with strategic objectives. I thrive in environments that value collaboration, learning, and innovation, and I’m always ready to tackle the next big challenge with creativity and enthusiasm.
