The whole system.
The details that matter.

Connect on LinkedIn

I build, modernize, and maintain complex enterprise applications, connecting frontend architecture with backend services and the people who use them.

My work spans real-time collaboration, authentication and permissions, data processing, automated testing, and production support. I lead technical decisions, review code, mentor developers, and stay involved from architecture through delivery.

Frontend architecture
Vue, Nuxt, TypeScript, Pinia, TanStack Query, Nuxt UI, React, Next.js
Backend & real-time systems
NestJS, Node.js, REST APIs, WebSockets, JWT, RBAC
Data & asynchronous processing
PostgreSQL, SQL Server, Redis, Prisma, TypeORM, BullMQ
Mobile engineering
Flutter, facial recognition integration, geolocation
Quality & delivery
Playwright, Jest, Vitest, GitHub Actions, Docker, CI/CD, code reviews
Development practice
System design, UX workflows, Gitflow, specification-driven development
INDEPENDENT ENGINEERING / IN DEVELOPMENT

Forge Finance

A personal finance platform connecting a Nuxt web application and a Flutter mobile client to a modular NestJS backend in a shared monorepo.

I build event-processing pipelines for transaction capture, parsing, reconciliation, and enrichment using PostgreSQL, TypeORM, Redis, and BullMQ. The implementation includes duplicate prevention, worker retries, failed-event reprocessing, JWT authentication with token revocation, and backend unit tests.

    Senior Developer

    Lead technical delivery across enterprise collaboration, asset operations, and document automation, with ownership of business-critical modules from architecture to production support.

    • Guide a seven-developer team through technical decisions, code reviews, mentoring, implementation planning, and shared development conventions.
    • Led a React/Next.js to Vue/Nuxt migration while maintaining operational continuity and data integrity. Improve rendering, caching, pagination, and API communication.
    • Develop backend services and integrations, and establish automated quality checks. Design UX workflows for 800+ internal and external users alongside code reviews, Playwright E2E testing, and GitHub Actions quality gates.
    Real-time collaboration
    Build task-management interfaces with Kanban, calendar, and list views in Vue, Nuxt, and TypeScript. Use TanStack Query and WebSockets for live updates, cache synchronization, reconnection, and notifications.
    Enterprise asset operations
    Develop data-heavy interfaces for inventory, inspections, service workflows, and operational reporting. Structure reusable components, advanced filters, cursor-based pagination, organization context, and permission-aware navigation.
    Document & report automation
    Develop NestJS services combining pdfmake, Chart.js, and Puppeteer-driven visual rendering. Separate document composition from browser capture, control rendering concurrency, and optimize report images.
