👋 Hi, I'm Parth. 🏆 Expert-Vetted (Top 1% on Upwork) | ⭐ 100% Job Success | 💰 $200K+ Earned | ⏱️ 8,600+ Hours I build production software end to end. React and TypeScript on the front, Node and PostgreSQL behind it, and AI where it actually makes the product better. Most of my work is SaaS: multi-tenant platforms, dashboards, internal tools, and the APIs that power them. 8+ years shipping software teams use every day, with engagements that run two to four thousand hours, because clients keep me around. ━━━━━━━━━━━━━━━━━━━━ ⚙️ Backend Node and Express APIs with authentication, role-based access, third-party integrations, file uploads, and background jobs. PostgreSQL schemas designed properly, Prisma models and migrations, query optimisation, indexing, and transactions. 🤖 AI & Automation OpenAI and Claude integrations in production for chat, content generation, and workflow automation. RAG pipelines with LangChain and vector databases for document search and Q&A. AI agents that talk to external tools and APIs. And AI-assisted development (Cursor, Claude) in my daily workflow, with my own judgment on everything before it ships. 🎨 Frontend This is where I go deepest. React, Next.js, Angular, TypeScript, Tailwind. Design systems, component libraries, data-heavy dashboards, Figma to pixel-accurate production UI, and performance work. 💳 Payments & ☁️ Infrastructure Stripe in production: one-time payments, subscriptions, webhooks, customer management. AWS deployments I run myself (EC2, S3, RDS, CloudFront), plus SSL, environments, and monitoring. ━━━━━━━━━━━━━━━━━━━━ 💬 What clients say ⭐⭐⭐⭐⭐ "Amazing front end developer, thorough, and great communication skills." ⭐⭐⭐⭐⭐ "He not only delivered exceptional development work but also played a key role in architecting our entire application." ⭐⭐⭐⭐⭐ "It's very hard to find high quality developers, and we were very pleased with the work Parth did for us." ━━━━━━━━━━━━━━━━━━━━ ✅ Why clients stay ✔️ I take ownership instead of waiting for instructions ✔️ I communicate clearly and keep projects moving ✔️ I write clean, maintainable code the next developer won't curse at ✔️ I flag problems early instead of hiding them ✔️ I work like part of your team, not a freelancer passing through Most of my work comes from long-term clients and repeat collaborations. I think that says more than any list of technologies. ━━━━━━━━━━━━━━━━━━━━ 🛠️ My Stack 🎨 Frontend — React • Next.js • Angular • TypeScript • JavaScript • Tailwind • Material UI • Redux ⚙️ Backend — Node.js • Express • NestJS • REST APIs • GraphQL • WebSockets • JWT • OAuth 🗄️ Database — PostgreSQL • Prisma • MongoDB • Redis • Supabase 🤖 AI — OpenAI • Claude • LangChain • RAG • Vector DBs • AI Agents • Prompt Engineering ☁️ Cloud & DevOps — AWS (EC2, S3, RDS, Lambda, CloudFront) • Docker • Vercel • GitHub Actions • CI/CD 🔗 Integrations — Stripe • Twilio • Firebase • Auth0 • Clerk • Slack • and other third-party APIs ━━━━━━━━━━━━━━━━━━━━ 🚀 Building something and want a developer who can own the whole thing, front to back? Send me a message, I'd love to hear what you're working on.

🥇 Expert-Vetted (Top 1% on Upwork) | 14+ years shipping production web & mobile products - with AI built in where it adds value, not bolted on for show. I'm a full-stack & mobile developer and fractional CTO. I take ideas from concept to shipped, scaled products: the web app, the mobile app, the infrastructure, and the AI features that make them smart. My pedigree is enterprise - I started my career at SAP in Silicon Valley, the world's #1 enterprise software company, leading ML enablement and development across EMEA - but my home is hands-on building for startups and SMBs who need something real, fast. ⭐ On Upwork: 100% Job Success, 5-star rating, and long-term relationships spanning global corporations to solo founders. 🚀 A few recent builds: 🎓 IT Career Switch ➝ Custom LMS + 500 hours of AI-assisted course content in 8 weeks. Now their long-term innovation partner. 🍽️ The Munch Map ➝ Designed, built & scaled an AI-powered food-review SaaS app - 1m+ views in week one, hundreds of thousands of events weekly. 🎬 FilmWaffle ➝ Rebuilt & scaled an AI-powered film-discovery platform to 5m views/month, migrated with zero downtime. 📍 B2B venue finding platform ➝ Production venue-discovery platform (Django, React, Celery, PostgreSQL) with AI-powered semantic search. 🏢 Kandor ➝ Founding/fractional CTO on a full-stack web and mobile product, from architecture and AI through CI/CD to production. 🧪 Biosense ➝ AI-powered full-stack web app cutting manual root-cause analysis for biotech teams by up to 90%. 🗣️ Audico ➝ Architected & scaled a 40+ language generative-AI voice platform from concept to European commercialisation, as CTO. 📈 Prezien · 📚 Qirnas · ⚡ and more across SaaS, healthcare, edtech and travel. 🛠️ What I actually do: Full product builds and feature work - React, React Native, Expo, Flutter, Django / Node / Rust / FastAPI, PostgreSQL, Cloud (AWS, GCP, Azure, DigitalOcean etc...) & Kubernetes - with AI woven in where it adds value: semantic search, recommendation systems, knowledge graphs, smart automation, LLM-powered workflows, voice & generative features and more... Whether you're rapidly building an MVP, adding an AI feature to an existing app, or scaling to production, I bring a proven 14-year framework to get it shipped. 🚫 What I'm not the fit for: standalone model training, data labelling, analytics dashboards, or prompt-only engagements. I build intelligent products - not AI in isolation. ❓ WHAT MAKES ME DIFFERENT? 💡 Creativity ➝ Often overlooked in tech. I have a keen eye for design and love shaping tangible products and services. What we build will be bespoke to your exact needs. 🗣️ Communication ➝ Clients' #1 piece of feedback - and why they keep coming back. Most projects stall on misalignment, not code; a great developer who leaves you in the dark is still a liability. With 14+ years translating complex work for stakeholders at every level (a "Gifted Public Speaker" at SAP, Head of ML Enablement across EMEA, 200+ consultants trained), you'll always know where things stand and why. 🤝 Trust ➝ I run my own businesses, so I know how hard trust is to earn. I'm friendly, open and straight with you from day one, and I'm here for long-term relationships. I'd love to hear what you're working on - reach out and let's build something. You can count on an honest, timely, advisory reply every time 👍🏽

I'm an experienced developer who's created hours of award-winning tech-base live shows as part of Foxdog Studios. Nothing sharpens your skills like have 100s of people use your software while you stand in front of them on stage :). I've created, use, and live off a distributed multi-user web-based game engine and editor with live video/audio streaming, AR, body tracking, realtime VFX, scripting, etc. Written in TypeScript, Python and C++.
