in the United States

You need software that solves a real problem, built right the first time, by someone who understands your business and not just your stack. I’m Josh a US native full-stack engineer based out of Erie, Pennsylvania with 17+ years of experience building production systems for companies like Netflix, Universal Studios, Udacity, JPMorgan Chase, AmEx (Reserve/Resy), Namely, and startups backed by major tech founders. I specialize in taking ideas from zero → live product in days or weeks, not months. That means: Full-stack MVPs ready for real users Payment systems, auth, dashboards, and admin tools AI features (agents, RAG, MCP Servers, inference, video processing, chat, automation, workflows) where they actually add value not hype Clean, scalable architecture so you don’t have to rebuild later If you need someone who can think like a founder and execute like a senior product engineer, I’m your guy. 🚀 WHAT I BUILD I help founders and teams ship: SaaS MVPs (Next.js, Node, React, Postgres) AI-powered products (chatbots, RAG based search, MCP Server, inference, video processing, agents, and intelligent workflows that improve product output) Internal tools & dashboards - help CSMs or other stakeholders better use your data Marketplace & subscription platforms API-driven backends & integrations Payment systems (Stripe, billing, subscriptions) Mobile apps (React Native / Expo) If it needs to launch and make money I can build it. 💼 EXPERIENCE THAT ACTUALLY MATTERS I’ve built systems used at scale, including: Chase - UI component systems for enterprise banking products PINCHme - helped scale to 1M+ users handling flash traffic events Resy / Amex (Reserve) - reservation systems with distributed backend architecture The Daily Beast - custom editorial and publishing tools Namely - HR/payroll platforms in regulated environments ChampPlan - Insurance/Benefit/Payroll platform with data dashboards Udacity - AI-driven education systems and product experimentation I’ve worked across startups, enterprise, and high-traffic consumer platforms, so I know how to build things that don’t break when real users show up. ⚙️ TECH STACK Frontend: Next.js, React, Tailwind, React Native Backend: Node.js, NestJS, Rails, REST & GraphQL APIs Database: Postgres, MongoDB, Redis Infra: AWS, Vercel, CI/CD pipelines, Docker AI: OpenAI, Claude, LLM integrations, RAG systems, automation workflows Payments: Stripe, subscriptions, billing systems Integrations: APIs, webhooks, third-party systems ⚙️ HOW I WORK I scope like a product engineer, not a freelancer I focus on what makes your product actually usable and monetizable I ship in tight iterations so you always have something working quickly I design for scale from day one, not rebuilds later Most clients come to me with an idea. They leave with a live product. 🫶 WHY CLIENTS HIRE ME 16+ years building production systems Strong product + engineering thinking (not just code execution) Fast turnaround on MVPs (7–14 days typical for early builds) Clear communication and proactive updates Focus on revenue-ready outputs, not just features Experience across startups + enterprise environments 📩 LET’S BUILD IT If you’re serious about launching your product, send me a message with your idea. I’ll reply with: A loom video A quick technical approach Suggested MVP scope Timeline + rough cost estimate No fluff. Just clarity on how to get it built. 🔧 EXPERTISE React JS Next JS Angular JS Solid JS Vue JS TypeScript React Native (IOS/Android) Node JS Development Microservices / Service Oriented Architecture Nest JS Express JS Mobile App Development Python FastAPI Django Ruby on Rails Go C# Shopify Development E-commerce Development Magento Development Website Development User Flows + UI & UX ThreeJS GSAP VR Development MR Development MySQL MongoDB MariaDB PostgreSQL Amazon Dynamo DB Amazon Aurora Supabase Convex Redis Memcached Nginx HAProxy Elasticache Docker Kubernetes Jenkins Google App Engine Amazon Elastic Container Service Amazon IAM Amazon Elastic Beanstalk Amazon Lambda Amazon EC2 Amazon Fargate Amazon EBS Amazon AWS CLI Elasticsearch Google Analytics Datafast Datadog New Relic Amplitude Posthog A/B Testing 🧠 DOMAIN EXPERIENCE SAAS B2B B2C Shopify apps E-commerce software Restaurant management software Booking service software Food delivery software Social network software News network software CRM software HR software Insurance software Data Dashboards Service marketplace Digital and physical product selling software Event ticket software Dating apps Mixed Reality experiences (AR/MR) Education or E-Learning software Fintech software Real estate software Asset valuation software Crowdfunding software Ad tracking software Whitelabel software Video processing software AI analysis software RAG search or ingestion software and I'm probably missing some others 😅
