Project details
Built a full stack B2B admin dashboard as the sole full stack developer — a complete operational control panel for a SaaS platform managing dealer partners, subscriptions, and real-time inventory data.
The dashboard gives platform owners full visibility and control: dealer onboarding and activation, subscription status tracking, one-time vs recurring payment monitoring, and live database health — all in one interface. When a dealer completes payment via Stripe, their data is automatically written to PostgreSQL and instantly reflected in the admin panel without manual intervention.
Role-based access control separates super admin and admin permissions — each level sees exactly what they need and nothing more. Authentication includes secure login, password reset, and session management built directly into the full stack architecture.
The analytics layer shows platform-wide activity at a glance — active dealers, inventory completeness, subscription expiry, and payment history — giving the business owner the information needed to make decisions without querying a database.
Built with Next.js, React, Node.js, PostgreSQL, Stripe, and Vercel.

I can honestly say that working with Svitlana has been one of the best experiences I've had on Upwork, or any other platform.
From the very beginning, she understood exactly what I was trying to achieve and consistently went above and beyond to improve my ideas and bring them to life. The quality of her work has been exceptional throughout, and her communication has been just as impressive. I always knew what had been completed, what was being worked on next, and she was always available to answer questions or discuss new ideas.
Nothing was ever too much trouble, and her attention to detail and commitment to delivering the best possible result really stood out. The finished project has exceeded my expectations, and I couldn't be happier with the outcome.
I wouldn't hesitate to hire Svitlana again for future projects and would highly recommend her to anyone looking for a talented, reliable, and professional designer. Thank you again for all your hard work—I look forward to working together again in the future.

Everything was done deeply and thoughtfully, with real care taken to make it all clear and easy to follow. Special thanks for how accessibly it was all explained . The work was delivered on time, and what I got in the end wasn't a dry report but a genuinely useful action plan.

I accidentally duplicated my contract with Svitlana, which is why I am canceling - my error. I have worked with Svitlana quite a bit in the past, I am working with her currently, and I am sure to continue to in the future. She is a pleasure and a very clever solutions artist in automations, particularly between backend websites, Make, and Go High Level. Tremendous worker and kind human being. I highly recommend her.

Job Success
Bexhill-on-Sea, United Kingdom - 6:00 am local time
I am a full stack developer, SaaS developer, and dashboard developer in the UK.
As a full stack developer I own the entire stack — PostgreSQL design, Node.js and Nest.js backend, React and Next.js frontend, REST API integrations, Stripe payments, and Vercel deployment. Need a full stack developer, SaaS developer, or dashboard developer who owns the technical side end to end? Let's talk.
My recent full stack developer work includes a SaaS platform for trades businesses — a Next.js app with job management, client records, quoting, and role-based access — and a B2B admin dashboard on PostgreSQL, Node.js, and React that a team of 20 depends on every day.
Technical consultant. Architecture. Audit.
For non-technical founders my tech stack and architecture audit with written report shows what you have, what's broken, and what to build next — vendor selection, developer estimate review, security review, and a roadmap. As a Next.js performance specialist I improve Lighthouse and Core Web Vitals — measurable gains for users and search ranking.
SaaS developer. Multi-tenant. Production-ready.
As a SaaS developer I delivered a multi-tenant SaaS starter on Next.js with Stripe subscriptions, PostgreSQL via Neon, role-based access, billing portal, and team invites — fully documented, repo transferred on handover. I led a platform rebuild from legacy PHP and WordPress to a modern Next.js and Nest.js architecture — 40% lift in user engagement post-launch. I also build multilingual B2B platforms — Next.js with Sanity CMS, localised content and routing, editorial workflows non-technical teams actually use.
Security audit. Supabase RLS. Multi-tenant isolation.
As a technical consultant I run pre-launch security audits for SaaS founders — the review that must happen before real customer data goes live. My audits cover Supabase Row Level Security (RLS), multi-tenant isolation, PostgreSQL policy design, authentication flows, and exposed API keys in client code. I've audited a multi-tenant property maintenance SaaS on Supabase, and on another platform found RLS policies that lived only in discarded migrations, never applied to the database — the silent data leak an audit catches before a breach. If you're a SaaS founder on Supabase, Next.js, or PostgreSQL and aren't certain your tenant data is isolated, that's the audit I do.
Backend developer. Nest.js. PostgreSQL. Data pipelines.
As a backend developer I build production Nest.js and Node.js APIs on PostgreSQL with TypeScript end to end. Recent backend work: a Nest.js and PostgreSQL backend for a raffle SaaS platform — JWT authentication, OAuth providers, password recovery, and a clean REST API layer for a Next.js and React frontend. I also engineered a web scraping and data aggregation engine: Nest.js cron pipelines with adapters for multiple third-party sites, anomaly detection, stale-data cleanup, and webhook alerting — thousands of records refreshed daily on Railway, Prisma, and Neon. Every endpoint authenticated, every role enforced, every query isolation-aware.
Dashboard developer. AI features. Data that changes decisions.
As a dashboard developer with a KendoReact commercial licence I build enterprise-grade interfaces standard React developers can't replicate — advanced data grids, real-time charts, complex forms under load. My portfolio includes a marketing analytics dashboard with AI insights that cut campaign review time by 60% for a British agency, and a SaaS analytics dashboard with Chart.js and PDF export that replaced weekly manual reporting. I integrate LLM APIs (Anthropic Claude, OpenAI) into production apps — AI insights, content pipelines, and matching features, keys secured server-side.
Integrations. Authentication. Infrastructure.
OAuth integration and API authentication — credential flows for Google, GitHub, and custom providers using NextAuth, Nest.js, and JWT. Google Tag Manager with GA4 and Meta Pixel across complex Next.js apps, GDPR cookie consent and Consent Mode included. Transactional email on Resend and Brevo, plus Next.js blog and CMS setup with Sanity Studio.
Stripe. Payments. Automation.
I built a Stripe internal payment interface with role-based access on Next.js — PaymentIntent flow, full audit log, zero card data stored. I delivered Stripe subscription billing with webhooks handling upgrades, downgrades, and failed payment recovery. I wire Stripe with Make, GoHighLevel, and Google Sheets so every transaction triggers the right email, CRM tag, and notification.

Requirements & Architecture
I review your platform, define the database schema, role structure, and admin panel architecture before writing any code.
Authentication & Role-Based Access
I implement secure login, password reset, and role-based permissions — super admin and admin levels with separate access controls.
