Fullstack engineer owning the redesign and evolution of a multi-cloud security SaaS platform, spanning database architecture, backend systems, and distributed microservices.

• Redesigned the database architecture, eliminating duplication and ambiguous JSON structures by introducing normalized relational models, including a normalized base/specialized credentials schema and full historical scan tracking

• Led a full-system refactor across backend (Node.js/TypeScript), frontend (Next.js), and Go microservices, eliminating loosely typed logic and duplicated code while enforcing clear service boundaries and scalable structure.

• Maintained and developed an asynchronous, event-driven scan pipeline using Go microservices and RabbitMQ, orchestrating multi-stage cloud security scans, resource mapping, and report generation.

• Implemented secure Stripe billing integration with webhook-driven synchronization, idempotent event handling, and normalized data models for products, prices, and subscriptions.

• Strengthened system reliability and developer experience by adding comprehensive documentation (architecture, workflows, messaging) and high-coverage Go testing (unit, integration, & E2E testing).

Developed a Next.js-based e-book reader app, improving workflows and the user experience. Utilized ReactJS, Tailwind, TypeScript, Next.js, and Capacitor for cross-platform compatibility.

• Developed the key app features, including multi-mode e-book reading, and a text highlight annotation system.

• Implemented a swipe navigation feature for seamless page transitions and a page previews slideshow for enhanced user experience.

• Adopted Component-Driven Development with Storybook, refactoring UI components for isolated testing, and accelerating UI/UX iterations.

• Containerized the backend, dashboard, and app with Docker, streamlining the development environment by introducing a Docker-based workflow with hot-reloading, reducing developer onboarding time and complexity of running the projects to a single command.

• Built a CI/CD pipeline for automated testing and deployment to AWS S3 and CloudFront, managing Storybook deployments, domains, SSL certificates, and enforcing code quality with git hooks to ensure error-free commits.

• Integrated Capacitor for cross-platform mobile compatibility, enabling the app to be deployed across both web, android, and iOS platforms.

Worked on a full-stack system for rendering and processing PDF books and articles, using MongoDB, Express, Angular, NodeJS and TypeScript.

• Tackled a complex and unmaintainable codebase, refactoring it to enhance maintainability, readability, and overall code quality, simplifying future development.

• Enhanced the project dashboard by implementing substantial features, including image-processing capabilities like watermark removal, and advanced data processing with drag-and-drop UI elements.

• Extended backend functionalities, creating aggregation pipelines, improving the database schema and integrating with Google Sheets API, Google Cloud Storage, and AWS.

• Segmented and hosted the backend server separately on AWS to improve the system architecture and established an automation pipeline (CI/CD) to build and deploy the project to AWS automatically.

Led the development of the full-stack recruitment system, which includes the registration website, dashboard website, and backend API & database, using React, NodeJS, Express, MongoDB, TypeScript & more.

• Replaced the need for 80% of the external services needed for the recruitment processes, such as Google Forms & Google Sheets, by implementing participant's state tracking & automatic email sending.

• Removed all needs for paperwork in recruitment processes by developing interview notes & rating features.

• Implemented security measures such as authentication, authorization, and logging for actions to trace any action done on the system, as well as rate-limiting

• Ensured usage of latest technologies, best practices & code quality, through the usage of TypeScript, reviewing pull requests, adding swagger to the API, etc.

Contributed 30+ PRs improving performance, UI, and features

Developed 6+ reusable UI components from Figma designs
