Description

I help product teams ship reliable, performant web applications without the overhead of a full hire. My core stack is Node.jsGolang and Vue.js/TypeScript, with 7 years of building fintech platforms, real-time products, and high-traffic sites from backend services through to polished frontends. Experience in both enterprise and startup environments.

What I typically deliver:

microservice architecture and API design in Go or Node.js
Vue.js/React frontend builds with component libraries and testing infrastructure
CI/CD pipelines with Docker and Kubernetes
PostgreSQL performance optimization.

I handle the full delivery cycle: backend services and APIs, frontend interfaces, infrastructure, and monitoring.

Best fit for embedded engineering roles in product teams, greenfield service builds, frontend-heavy projects needing backend awareness, and performance or reliability work on existing systems.

I work best on projects where I own a feature end-to-end, from database schema to UI, collaborating directly with product and design to move metrics that matter. Whether you need a senior engineer embedded in your team for a few months or a focused build of a new service or frontend, I can start within days and deliver production-ready work.

NexusSystems
Full-Stack Engineer
February 2022 - December 2025 (3 years and 10 months)
Built and maintained full-stack applications in an 8-person team, working on
a fintech platform with 50K+ active users. Backend was a Golang microservice
architecture and frontend was Vue.js (Vue 3 + Composition API, TypeScript).
Partnered with product and senior engineers on key architectural decisions.
- Optimized Golang microservices, reducing P95 latency for critical API
endpoints from ~800ms to ~500ms via connection pooling and eliminat-
ing N+1 queries
- Introduced Vite and Storybook for shared Vue components, cutting frontend build time from 4 minutes to 45 seconds and simplifying UI reuse
- Built a testing infrastructure using the Go testing framework and Cypress,
reaching 85% coverage across critical flows (authentication, payments,
user dashboard)
- Helped migrate the payments module from a monolith to Golang and Docker microservices, enabling the team to deploy payments independently of the main product
- Set up a CI/CD pipeline with GitHub Actions, Docker and Kubernetes,
including automated rollbacks and staged deployments to staging and
production, and automated infrastructure provisioning with Terraform
plus Prometheus/Grafana monitoring to track latency and error rates
across services
- Optimized PostgreSQL queries for the main dashboard (indexes, rewrit-
ten JOINs), reducing page load time from 3.2s to 1.8s
- Built and maintained supporting Python services in Django and FastAPI for internal reporting and admin tools (user/account management, trans-
action exports, and audit views), exposing REST APIs that integrated with the Golang microservice stack and PostgreSQL
- Mentored two junior developers through code reviews and pair program-
ming, helping them understand microservice architecture and the Vue Composition API and grow into independent contributors
GO PostgreSQL VueJS Docker Terraform
ConnectHub
Engineer
March 2021 - January 2022 (10 months)
Co-founded ConnectHub as the technical co-founder and led the engineering
side of a real-time social messaging platform (group chats and media content).
In a 4-person team, owned Node.js services, Vue.js frontend, and produc-
tion operations, working closely with the product owner to scope and deliver features.
- Designed and built a full-stack application from scratch on Node.js and Vue.js/TypeScript, scaling it from MVP to thousands of concurrent users
with real-time messaging
- Implemented RESTful APIs and WebSocket servers for real-time features
(chats, notifications, live reactions), increasing average session time from
8 to 20 minutes
- Ran load testing and tuned autoscaling and rate-limiting configura-
tion, keeping critical real-time features at 99.9% availability during peak launches
- Developed backend services on Node.js with Nest.js and Socket.io, han-
dling 30K+ messages per day with sub-200ms response times
- Designed a multi-database architecture with MongoDB for real-time data and PostgreSQL for relational data, optimizing data flows between ser-
vices
- Built shared state layers with Pinia and Vuex plus Redis/Kafka pipelines
to keep real-time features consistent across clients
- Implemented CI/CD with Docker and AWS (EC2, S3, CloudFront) and set
up monitoring and alerting with Prometheus, Grafana and Sentry for key
metrics (errors, latency, delivery rate), delivering reliable deployments
and more than halving average incident response time
- Migrated the frontend from Vue 2 to Vue 3 with the Composition API
while keeping backend compatibility, allowing the team to expand the
codebase significantly
NestJs External API integration IT Architecture Amazon Web Services Nuxt.js
Velocity WebStudios
Front-end Engineer
January 2019 - February 2021 (2 years and 1 month)
Developed client web applications with a focus on responsive interfaces and
backend integration, delivering 12+ production sites and apps for e‐commerce,
SaaS, real estate, streaming, marketplace, and marketing clients.
-Built responsive sites and applications using Vue.js 2 and SCSS, ensuring
cross-browser support and a mobile-first layout for desktop, tablet, and mobile breakpoints
- Improved the frontend toolchain with webpack optimizations and Storybook-driven component workflows, cutting build times by 30%
and standardizing a shared UI component library reused across multiple
client projects
- Implemented REST API integrations for dynamic content management
and authentication systems, working closely with backend developers to
define and maintain explicit API contracts
- Worked with MySQL to build data-driven web applications, including CRUD interfaces and dashboards for managing products, content, and
customer data
- Added Cypress and Jest regression suites and automated Lighthouse
checks, reducing post-release UI defects by 24%, pushing performance/ac
cessibility scores above 90 on core pages, and contributing to a 10–15%
conversion lift on key signup and marketing pages
- Contributed interactive components in React on several projects, extend
ing the stack beyond the company's primary Vue.js focus for clients whose
stacks standardized on React
VueJS CSS3 Cypress SASS Front-End development
