About Me

I've had the privilege of working for companies in insurance, mortgage, travel,finance, advertising, and most recently, for a software startup. This diverse experience has given me the opportunity to build my problem-solving and analytical skills in various environments, become an effective team player, and gain knowledge of multiple development approaches, technologies, and frameworks.

Software engineering isn't just my job or expertise - it's a way of life that combines passion, creativity, and continuous improvement through learning new things. It's not just what I do, but who I am.

Work Experience

  1. May 2019 — Present

    SOWADEV is a software development startup specializing in web applications and mobile development, e-commerce, and cloud technology solutions for corporate clients. I developed e-commerce and retail solutions for multiple projects, and built the new modern corporate website that significantly increased performance and traffic.

    • Led the effort to design and prototype the frontend for IWWI e-commerce platform within a cross-functional team of developers, designers, and the product owner while actively contributing to day-to-day development of the front-end components and project libraries (Next.js, JS, Tailwind CSS, Figma).
    • Overhauled the codebase (JS utilities, components and style libraries, custom web hooks) for IWWI, MAXIMA, and Eco Spirits projects to improve code modularity, reusability, and promote separation of concerns.
    • Collaborated with the MAXIMA retail chain 's back-end team on optimizing the communication between front-end and the new REST API handling supply chain transactions. This addressed the problem with data sync delays, added real-time delivery updates, and reduced the response time for the most critical requests 5-6X.
    • Migrated MAXIMA intranet services for supply chain data uploads and reporting to the serverless platform (Google Cloud Functions), achieving 99.9% uptime and significantly improved scalability.
    • Designed and built the SOWADEV agency's current website using Jamstack and CSS animations that represented a major UX upgrade from the original version, improved the page loading time by 4.5X, reduced the total size of loaded assets by 6X. Updated the back-end with a Google Cloud function using Nodemailer for handling contact forms, emailing, and Firestore logging. Optimized site performance and SEO features to align with Google Search Console best practices.
    • Assisted the PM in implementing Scrum/Agile practices and procedures, which resulted in creation of efficient, fast-paced development environment and shortened the project development cycle by 20%.
