As a Staff Engineer at PandaDoc, I drove several impactful initiatives that significantly advanced the company’s technology and business capabilities:

• Localization Initiative: Led the end-to-end localization of PandaDoc’s application, localizing 200+ microservices. Conducted research, developed the strategy, selected tools and oversaw implementation. Acted as product manager, delivery manager, and team lead for three development teams, ensuring seamless execution. This project enabled PandaDoc’s expansion into European markets, unlocking new revenue opportunities and eliminating the need for external expertise, saving significant resources.

• Frontend Observability: Designed and implemented a centralized observability solution for over 60 frontend services, integrating RUM, logging, and metrics, and building Grafana dashboards to enhance monitoring and performance insights.

• Sentry Upgrade: Successfully upgraded Sentry across two major versions for all frontend applications, improving error tracking precision for micro-frontends and accelerating debugging processes.

• Backpack (Quality Management Tool): Led the development of the frontend and contributed to the backend of a tool designed to enforce engineering standards (RFM standard). Backpack improved the maintainability and discoverability of over 200 microservices. This initiative significantly enhanced product reliability and engineering efficiency at scale.

These efforts not only streamlined engineering processes but also delivered measurable business impact, showcasing my ability to drive large-scale technical initiatives and align them with strategic objectives.

As a Senior Frontend Engineer at PandaDoc, I played a pivotal role in advancing the quality, functionality, and scalability of the company’s frontend ecosystem.

One of my key contributions was leading the development of the "inline comments" feature for real-time collaboration on electronic documents—a critical functionality that significantly enhanced the product’s collaborative capabilities. Acting as the frontend architect and team lead across two frontend teams, I was responsible for defining the architecture, coordinating cross-team delivery, and ensuring the seamless implementation of the feature. This initiative not only expanded PandaDoc’s use cases but also attracted a broader audience by positioning real-time collaboration as a core functionality.

In addition, I played a pivotal role in migrating JavaScript services to TypeScript, which improved code maintainability, enhanced developer experience, and increased overall application stability. As part of this effort, I contributed to restructuring a large-scale service with over a million lines of code. This restructuring reduced technical debt, decreased system complexity, and significantly improved contribution times for the team, enabling faster and more efficient development.

Throughout my tenure, I drove improvements in code quality, optimized team workflows, and delivered features that elevated the user experience, directly contributing to PandaDoc’s growth and success.

During my time as a Fullstack Developer at Itransition, I contributed to three key projects, gaining experience in diverse domains and strengthening my technical and leadership skills:

1. Ev***io – Software for awards organizers to manage programs online. As a fullstack developer, I implemented new features based on specifications and solved various product tasks using Python (Flask, SQLAlchemy), JavaScript (jQuery, AngularJS), MySQL, AWS, and Scrum methodologies.

2. Eq***m – A financial modeling application where I helped create reusable components using modern frontend technologies such as ReactJS, GraphQL, Effector, and AG Grid, improving the efficiency and scalability of the application.

3. Tr***ry – Financial planning software where I took on multiple roles: lead team of two developers. My key achievements were:
• Migrated the entire codebase to TypeScript, ensuring maintainability and introducing comprehensive test coverage.
• Transitioned the architecture to a serverless setup using AWS Lambda, significantly improving performance and scalability and cutting costs.
• Optimized the backend engine’s performance, enhancing overall application responsiveness.
• Led the implementation of advanced frontend visualizations with React, Redux, D3.js, ChartJS, and Storybook.
• Designed and deployed infrastructure using AWS CDK, with a focus on DynamoDB, AWS Gateway, and AWS Amplify.

This period allowed me to deepen my technical expertise, take ownership of critical systems, and contribute to both technical excellence and product outcomes, preparing me for greater challenges in my career.

Started my career as a Freelance Developer, delivering tailored solutions to meet diverse client needs. I developed websites, created custom scripts in JavaScript and Python, and tackled a wide range of small-scale tasks for various projects.

This experience not only strengthened my technical skills but also helped me develop a product-oriented approach to development and a sense of strong ownership over the solutions I delivered. It laid the foundation for my ability to align technical execution with client and business goals, a mindset that has guided my growth as a software engineer.
