About

Professional summary

I am a senior full-stack engineer with more than six years of experience building production web systems. My strongest areas are TypeScript, frontend architecture, and end-to-end delivery across regulated and user-facing products.

I build frontend applications with Angular, React, Next.js, Vue, and Blazor. I have led migrations from Vue 2 to Vue 3, introduced TypeScript into established codebases, and developed reusable component libraries used by multiple teams.

On the backend, I work with .NET, Node.js, Ruby on Rails, PostgreSQL, SQL, REST APIs, GraphQL, and WebSockets. I am comfortable owning systems from an empty repository through data modeling, authentication, API design, deployment, and production support.

I have recently served as the sole developer for greenfield healthcare administration and mortgage lending platforms. These projects included secure authentication, document-processing workflows, administrative dashboards, and LLM-powered document analysis.

I use AI-assisted development thoughtfully as part of my delivery process. I have redesigned LLM agent rules and workflows in a production team, reducing agent errors by approximately 40% and increasing delivery velocity by about 2.5 times.

I value reliable engineering practices, including automated testing, canary releases, production telemetry, secure OAuth and OIDC authentication, and clear asynchronous team workflows. I am open to remote opportunities across EU and US working hours.

Career history

Senior Software Engineer NextBridgeIT

I serve as the sole developer for a healthcare administration platform built from an empty repository. I own the .NET API, Angular administrative dashboard, data model, API design, authentication, and delivery process.

I also built a mortgage application platform end to end, including frontend and backend functionality, borrower document intake and processing, and LLM-powered document analysis. Additionally, I joined a four-person healthcare team and took ownership of a module across frontend and backend using .NET, C#, Angular, Blazor, Azure DevOps, and Claude-assisted workflows.

Software Engineer Grid Dynamics

I redesigned internal LLM agent rules and workflows, reducing error rates by approximately 40% and increasing team delivery velocity by about 2.5 times. I also led development of a scheduling and geolocation module for a national US apparel retailer that runs in production across its store network.

I delivered features through a Jenkins canary release pipeline, validating rollouts against New Relic telemetry before production promotion. My work included secure OAuth authentication with PKCE, development across Ember.js and Vue codebases, and production monitoring and diagnosis with New Relic.

Frontend Developer Cramick-IT

I worked as a frontend developer on user-facing product development. I contributed to building product functionality from an empty repository through pre-release.

My work focused on frontend implementation and establishing a foundation for the product experience.

Software Engineer Symphony

I contributed to frontend architecture for a React and Next.js application. I implemented microfrontends using Webpack Module Federation and helped design a hybrid HTTP and WebSocket communication model.

I implemented authentication using Okta and OpenID Connect and contributed to Node.js services in a microservices environment.

Frontend Developer / Product Manager Cramick-IT

I led a Vue 2 to Vue 3 migration across two codebases, including a larger application spanning approximately ten modules. I introduced TypeScript to both codebases and developed reusable Vue and Quasar component libraries used across teams.

I implemented real-time WebSocket features and took product ownership beyond implementation by shaping feature behavior. I also improved team operations by replacing standing meetings with asynchronous workflows and clearer ownership.
