I'm a Full-Stack Engineer specializing in React, Next.js, React Native, Node.js, and PostgreSQL, with experience building and shipping production web and mobile applications for startups across the USA, UK, and Israel. Over the past 2+ years, I've worked on SaaS platforms, mobile apps, e-commerce systems, AI-powered products, and content automation tools.

Over the past 5+ years, I’ve worked with startups and growing teams to turn ideas into fast, reliable, and production-ready applications. Some clients come in with a rough concept, others with a broken app either way, the goal is the same: clean code, smooth performance, and something that actually works in the real world.

Hello 👋 — I'm Rob. **I ask a lot of questions.** Not because I'm unsure — because assumptions kill projects. And not just on day one. Assumptions get invalidated constantly as a product evolves, so I keep asking. Tight feedback loops beat big upfront answers every time. I build web apps that ship. My default is SvelteKit (faster for 99% of projects), but I've shipped plenty of Next.js/React and will happily work in your existing stack without trying to convert you. **Here's how I'm different:** Most devs defend one framework. I focus on delivering low friction, high user satisfaction outcomes underpinned by data. I use LLMs to move fast, but I override them constantly because most AI is trained on average developer output. You get AI speed + human judgment. **What working with me looks like:** - I ask questions throughout the project, not just at the start. New information changes things. I'd rather adjust constantly than build the wrong thing perfectly. - Daily Loom videos or written updates — no disappearing acts - Tight feedback loops — we validate before we build too far - "Break stuff fast" (metaphorically) to find what users actually love - No perfectionism. Just working software your users want to use. **My goal for your project:** Simple, Lovable, Complete (SLC). Not perfect. Just done and loved. **Best fit for:** - MVPs that need to launch yesterday - Internal tools no one wants to maintain - Existing apps that feel over-engineered and slow - Greenfield projects where you want someone who picks the right tool, not their favorite **Core stack (primary → secondary):** - Frontend: SvelteKit (default), Next.js/React (when needed) - Backend: Node.js, Express, Fastify - Databases: Postgres, MongoDB, MySQL - Styling: Tailwind, Bootstrap - Real-time: SocketIO, REST, GraphQL - AI tools: v0, Replit, Lovable — I use them all, but I drive, they don't drive me **Also experienced with:** Astro, Remix, Feathers, SanityIO, Contentful, Shopify, WordPress, C#, Java, Linux **Past results:** Helped deliver ~$1M/year in services for my division. Killer client feedback available on my profile. Let's talk about what you're building. I'll probably have questions — and that's a good thing.

Full-stack SaaS developer specializing in Next.js, React, TypeScript, Supabase and Stripe. I build production-grade, multi-tenant SaaS platforms and web applications - from an empty repo to deployed and in use. I've shipped multiple production multi-tenant SaaS platforms and full-stack web apps, all with 100% Job Success on Upwork. The hard part of multi-tenant SaaS is usually not the features. It's making sure tenant A can never see tenant B's data, even by accident. I enforce that at the database level with Supabase Row-Level Security - not with app code you have to trust to get right every time. If you have an idea but no working app yet, I take it from empty repo to shipped: auth, Stripe billing, role-based access, and an admin panel to run it all. If you already have something half-built or AI-generated (Lovable / Cursor / v0) that needs fixing or scaling, I do that too. WHAT I BUILD - Full-stack SaaS platforms & MVPs - Next.js (App Router), React, TypeScript - Multi-tenant SaaS - isolated tenant workspaces, per-tenant data isolation with Row-Level Security (RLS) - B2B SaaS - self-service onboarding, role-based access control (RBAC), Stripe subscription billing - Admin dashboards & internal tools - user management, verification workflows, data tables - Custom CRM systems - lead management, pipelines, client portals - API & AI integrations - REST APIs, webhooks, OpenAI / LLM features - Data dashboards - real-time analytics, charts, automated reporting HOW I ARCHITECT MULTI-TENANT SAAS Most clients need the same thing: one codebase serving many clients, with strict data separation. Here's how I build it: - Per-tenant data isolation at the database level with Supabase Row-Level Security (RLS) - FORCE RLS and column-level access, so isolation never depends on app code being perfect - Layered role-based access control (RBAC) - platform, organization, and project permission levels - Object-level authorization on every endpoint - each request is checked against IDOR / broken access control (BOLA), so no user can reach another tenant's data by guessing an ID - Stripe subscription billing - plans, upgrades, usage limits per tenant - Self-service tenant onboarding - clients sign up and get a working workspace on day one - MFA/TOTP with step-up auth, secure session management and revocation - Immutable audit logs, hashed tokens/secrets, rate limiting and security headers - audit-ready, SOC2-aligned controls - Admin panel to manage tenants, users, verification queues and analytics from one dashboard RECENT WORK 1. Padel club platform - Multi-tenant SaaS for padel clubs - members, matches, rankings and sponsor banners, each club in its own isolated workspace. Supabase Row-Level Security for strict per-tenant isolation, self-service onboarding, one codebase serving many clubs. 2. Field operations B2B SaaS - Multi-tenant platform for field documents, dynamic forms and QA workflows. Layered RBAC with 13 roles across 3 permission levels, RLS-backed tenant isolation, MFA at the middleware layer. Custom formula engine, versioned form templates, server-side PDF generation, Stripe subscription billing, secure external document sharing. 100+ DB migrations, 105+ tests. 3. Real-time marketplace platform - Real-time SaaS marketplace with a full admin suite: user management, verification workflows, analytics, messaging and support tickets. Custom SQL functions for sub-second data aggregation and live updates across all connected clients. 4. B2B ordering MVP - Mobile-first ordering platform connecting restaurants and suppliers, with separate accounts for each side and an admin dashboard for suppliers, products and orders. Scoped as a lean MVP to validate the business model before scaling. MY STACK Next.js (App Router), React, TypeScript, Node.js, Python. Supabase and PostgreSQL for database and auth. Stripe for payments. Deployed on Vercel and Cloudflare for edge performance. I use Claude Code to ship faster without cutting corners. HOW I WORK 1. Discovery - I map your workflow, define MVP scope and agree on deliverables before any code. 2. Build - clean code, daily updates, working builds from day one. 3. Deploy - production-ready from launch, full ownership of the repo from the first commit. WHY CLIENTS HIRE ME - Security-first: every change is reviewed and pentested for IDOR, broken access control and RLS bypass before it ships - not bolted on after a breach. - 100% Job Success and Top Rated - I care whether the product is solid, not just whether it demoed well. - Full ownership from first commit to deployment. No handoffs, no lock-in. - A real product with auth, payments and admin wired up. Not a demo. - Clean, documented code you can extend, not a quick hack you rewrite in 6 months. Got a multi-tenant SaaS idea, a full-stack web app or an internal tool to build? Send a short description and I'll reply within 2 hours with a scope and timeline - or let's jump on a call. Let's get the ball rolling!
