I have used JavaScript from the days of jQuery DOM manipulation to complex UI architectures on a big scale in FinTech, build with React/Redux/Webpack. I have also used JavaScript in a full stack - Node app with MongoDB and express server for the API purposes.

My first project was B2B Content writing and SEO analytics tool where I honed my skills with Flux state management and React components lifecycle. I learned about a lot of internals and conventions to help speed up development and page performance. That's where I fell in love with easy to use and very performant React concept and it's environment (Webpack, babel) and continued to use it ever since on other production ready and large scale applications (FinTech customer support tool etc.)

Since the early stage of my career I've been doing full stack to some extent, but in the last 3 years I've been involved in more difficult tasks on the backend side, building CRUD endpoints with test coverage (Unit and Integration) in Ruby, as well as being the team captain for Continuous Integration and Docker support and other integration and code delivery scripts. I was mainly interested in full cycle (DevOps) from building the app to delivering it to the server itself. On one of my many projects I did the full server setup with separate microservices (Backend API + Frontend Client UI) with fast development cycles and code delivery using Digital Ocean, Capistrano, Github and CircleCI.

I have started my frontend career with HTML & CSS where I was developing and styling web pages and web apps using best styling practices and architecture (SMACSS, BEM, Atomic). My main focus is always on: - writing clean and reusable code - optimising for performance - developing cross device adaptive/responsive layouts

An AI-powered accounts payable platform to help you understand what’s driving your vendor spend with analysis and insights powered by machine learning.

Here’s what I did to rev up the team and product:

  1. Added key features towards our product stability and value
    • Payment processing and international payments were added which kicked off a revenue stream.
    • Added a feature to compare vendor spending. This gave users a clearer picture of their invoices and vendor spend.
    • Introduced UI tests which reduced QA time and increased product stability.
    • I also advocated for a more granular approach to building components. This not only made us more efficient but also busted some “knowledge silos”.
  2. Boosted team communication
    • We put in place a weekly team catch-up to iron out our engineering standards.
    • We fine-tuned our code review process by jotting down some key principles.
    • I also helped to create a technical roadmap to guide our decisions and ensure scalability.
  3. Fine-tuned our approach to feature discovery and product ownership
    • We assigned a ‘go-to’ person for each feature, which let engineers pinpoint potential roadblocks early.
    • We started splitting the feature into ‘must-have’ and a ‘nice-to-have’ tasks which resulted in better business planning.

All these efforts paid off big time.
We secured Series A funding, kick-started our revenue stream, grew our customer base, and built a solid track record of delivering high-quality features and products.
