About Me
I've had the privilege of working for companies in insurance, mortgage, travel, finance, advertising, and most recently, for a small software agency. My primary focus has always been on practical business impact.
I value a deep, foundational understanding of how things work under the hood. While mastery of React, Next.js, and related libraries is essential, experienced frontend engineers should also understand how the browser processes code, how the CSSOM and DOM trees interact, what triggers a reflow, when and how the painting and compositing phases occur in the browser rendering process, and how to optimize each step.
I leverage that knowledge to minimize reflows and layout shifts, design modular component hierarchies that avoid unnecessary rendering, and use performance-profiling tools to identify and eliminate bottlenecks. The result is a seamless user experience and a codebase that remains stable and maintainable as it scales.

- Led a cross-functional team of developers, designers, and UX experts to design, prototype, and deliver proof of concept for IWWI B2B platform front-end and service dashboards – while actively contributing to day-to-day programming and architectural tasks (Next.js, React, Tailwind CSS, Figma).
- Implemented modular architecture for reusable components, custom hooks, and utility libraries for MAXIMA, IWWI, and Eco Spirits projects, accelerating development time and improving code maintainability and accessibility.
- Developed the new SOWADEV website, quadrupling load speed and cutting asset size by six times.
- Assisted the Project Manager in implementing Agile Scrum practices and procedures, boosting team productivity and reducing the project development cycle by 20%.

I have completely redesigned the site and built it from scratch using Jamstack (JavaScript, HTML, and CSS). It features responsive mobile-first design approach, with animations and transitions.
I analyzed and optimized the website for performance, accessibility, and SEO using Lighthouse tool and Google Search Console.
Deployed to GCP Firebase plaform, the site uses Cloud Functions (Node.js/Express.js) to handle API requests, collect data from frontend, and log them to Cloud Firestore.

Scrum Smart Project introduced a SaaS application that enabled Scrum Masters to evaluate organizations' and development teams' agile adoption, plan the transition, and identify the areas for improvement.
I was responsible for developing major parts of the application frontend including assessment and contact forms, reports, and dashboards (all built in React), the app state management (Redux), email and OAuth authentication, and a library for handling data communication with backend (axios).
In addition, I have built a fully functional single-page application (SPA) demo app, which was utilized by the Marketing team in their presentations. This app features a streamlined design, leveraging React hooks, React context for state management, and Tailwind CSS for styling.

Living near the Kennedy Space Center, I can sometimes watch launches from the beach. This was a fun weekend project: an app that tracks the schedule of the upcoming missions from Cape Canaveral, complete with mission information and a countdown to the next launch.
The app is built using React/Vite and hosted on Vercel. The data is provided by NASASpaceflight LLC in HTML format; I have built an API proxy service (Node.js/Express.js) that fetches the HTML, parces it using JSDOM, and serves it in JSON format. The client app formats and renders the data, calculates and updates the next mission countdown.
