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!

I help startups and product teams fix unstable mobile apps, improve performance, and scale production systems, including apps with AI features, without breaking existing functionality. Clients usually come to me when their app is already live but facing issues that impact users, stability, or revenue. Common problems I solve: • Frequent crashes, ANRs, and unpredictable app behavior • Slow performance, memory leaks, and poor responsiveness • Payment failures or unreliable API integrations • AI features (chat, recommendations, automation) not working reliably • New features breaking existing functionality • Legacy code that is difficult and risky to modify Results I’ve delivered: • Reduced app crash rates by up to 40% by identifying and fixing root causes • Improved app performance and load times by optimizing memory usage and API handling • Stabilized production apps used by thousands of active users • Resolved critical API, payment, and backend integration issues • Integrated and improved AI-based features within mobile apps What I work on: • Native iOS & Android applications in production • Flutter (cross-platform) mobile apps • AI-powered features (chat, recommendations, automation workflows) • Payment gateway integrations and complex API workflows • Debugging crashes, ANRs, memory issues, and performance bottlenecks • Code refactoring, architecture improvements, and long-term maintainability • App Store & Play Store submissions, updates, and compliance How I work: • I solve root problems, not temporary fixes • I prioritize stability before adding new features • I write clean, maintainable, and scalable code • I leverage modern AI tools to speed up development, debugging, and testing while maintaining high code quality • I communicate clearly and take ownership of delivery • I ensure new changes do not break existing functionality CTA: If your app is facing crashes, performance issues, or unreliable features, send me a quick message with the details. I’ll review your app and suggest the fastest, safest way to fix and improve it.

I work across the entire stack and take ownership of infrastructure too. ⚡️ 𝗪𝗵𝗮𝘁 𝗜 𝗰𝗮𝗻 𝗱𝗼 𝗳𝗼𝗿 𝘆𝗼𝘂: + Build or extend back-end APIs (NestJS, Express, Django/DRF) + Develop full-stack web applications (React, Next.js + Node.js/Django) + Set up and manage server infrastructure (Docker, VPS, Nginx, CI/CD) + Integrate third-party services and payment systems + Improve and refactor existing codebases 𝗖𝗼𝗺𝗽𝗲𝘁𝗲𝗻𝗰𝗶𝗲𝘀: ⚒️ Back-End: NestJS, Express.js, Django/DRF, Node.js, TypeScript, GraphQL, WebSockets, Celery (Beat & Worker), Redis, JWT, AWS Cognito ⚒️ Front-End: React, Next.js (SSR/SSG), Redux, Zustand, D3.js, Chart.js, styled-components, Material UI, Ant Design, SCSS/SASS ⚒️ Databases: PostgreSQL, MySQL, MongoDB, Supabase — TypeORM, Prisma, Sequelize ⚒️ DevOps & Infrastructure: Docker, Docker Compose, Nginx, PM2, GitHub Actions, GitLab CI, VPS setup & management, SSH, DNS, SSL certificates, Cloudflare ⚒️ Cloud & Storage: AWS (S3, EC2), Cloudflare R2, Firebase, Supabase, GoDaddy ⚒️ Monitoring: Sentry ⚒️ Third-Party Integrations: ❇️ Payments: Stripe, Monobank, PayPal, Webhook solutions ❇️ Messaging: SendGrid, Mailjet ❇️ Documents: PandaDoc ❇️ CMS: Strapi, Contentful ❇️ Auth: AWS Cognito, JWT, OAuth2 ❇️ AI: OpenAI API ❇️ Other: AWS Amplify, Firebase On the back end, I build production-grade REST APIs and microservices using NestJS (TypeORM, PostgreSQL, WebSockets, GraphQL, Redis) and Django/DRF (PostgreSQL, Celery for async tasks, background workers).

I build AI agents and automations that connect directly to your CRM and business tools — GoHighLevel, HubSpot, Pipedrive, Zoho, n8n, Make — backed by 10+ years shipping production full-stack systems. Not prompt demos. Software that runs under real load. Most "AI experts" can wire up a chatbot. Few can take it to production — auth, data, error handling, scale, and clean integration with the CRM your business already runs on. I do both: I build the AI layer AND the full-stack system underneath it, so what you get holds up with real users and real data. 📈 WHAT I BUILD ✅ AI Agents & Automation Custom AI agents (LangChain, OpenAI, MCP, RAG, voice) that read and write your real systems — qualify leads, book appointments, route conversations, update records, trigger workflows. Wired into your CRM and APIs, not living in a sandbox. ✅ CRM & Workflow Automation Automated lead capture, qualification, pipeline management, appointment booking, and follow-up inside GoHighLevel, HubSpot, Pipedrive, Zoho, and Airtable — connected with n8n, Make, and custom code. ✅ AI Integration into Existing Products Add AI to the app you already have: chat, semantic search (RAG), document processing, summarization, agentic workflows — integrated cleanly into your stack. ✅ Full-Stack SaaS & MVP Development Multi-tenant SaaS, dashboards, billing, auth, and APIs on Laravel + React/Next.js — the production foundation AI features sit on top of. ✅ API Development & Integrations Secure APIs, webhooks, and third-party integrations (Stripe, Twilio, Mailgun, CRMs, LLM providers). 🏆 REAL RESULTS - Built a multi-tenant Laravel + Next.js SaaS CRM supporting 10,000+ active users - Delivered custom CRM integrations (Pipedrive, Zoho) connecting business data across apps and contracts - Migrated a legacy PHP system to a modern Laravel + React stack with zero downtime 🧠 WHY CLIENTS HIRE ME ✔ I ship AI to production, not just proof-of-concepts ✔ 10+ years of real full-stack engineering behind every build ✔ Top Rated Plus · 100% Job Success · $100K+ earned · 6,400+ hours ✔ Clear communication, reliable delivery, no overpromising If you want AI that actually connects to your business — your CRM, your data, your workflows — and holds up in production, let's talk.
