Senior Full-Stack Product Engineer

I joined dRPC, a blockchain RPC infrastructure company, as its first engineering hire and built the initial customer web application. I designed the PostgreSQL data model, built APIs with tRPC, developed ClickHouse integration layers, and delivered the React/Next.js interface for the production product.

I led the multi-tenancy rebuild, including invitations, tenant-scoped roles and permissions, reusable authorization middleware, and a zero-downtime migration of existing users. I also delivered enterprise invoicing with server-side PDFs and email delivery; integrated Paddle subscriptions, card payments, crypto top-ups, and x402 agent-payment handling.

I built customer and foundation analytics using more than 20 ClickHouse query modules, covering latency, uptime, block lag, and regional coverage. I resolved analytics memory issues, introduced server-side caching, designed a public key-management REST API and OpenAPI specification, and implemented wallet, email/password, and Google authentication with brute-force protection, audit logging, and regression tests.

I developed full-stack features for CureCloud and Immune Atlas, medical research platforms used for clinical research and data collection. My work used React and Python to create complex survey and form experiences.

I contributed to database design decisions and built the frontend for a medical cohort builder for the ASH Research Collaborative. I also introduced Playwright regression testing into the development workflow.

I worked on marketing tools and a full-stack content management system for Alfa-Bank. My work included frontend development and Node.js-based application functionality.

I contributed to CMS features backed by MongoDB and supported web experiences for marketing use cases.

I developed client web applications using React and TypeScript. I worked on user-facing product functionality and frontend integrations.

My work included integrations and visualizations using Jumio, Braintree, and Highcharts.

I developed analytics-focused web applications using React and TypeScript. I contributed to frontend engineering and product delivery within a large software services organization.

I also served as a mentor for a React course, helping other developers develop practical frontend skills.

I developed a web application for a Dutch startup. My frontend work used Backbone.js and Marionette.

I contributed to building and maintaining interactive browser-based product features for the startup's web application.

I created HTML5 templates and customer websites as a junior frontend developer. This role established my foundation in web interface implementation and client-focused delivery.

I worked on responsive web pages and supported the development of websites for customers.
