Need a full-stack developer who can own your product end-to-end frontend, backend, and everything in between and make sure it holds up under real users, from payments and permissions to third-party integrations? That's usually the point where a product needs someone who can handle the whole stack, not just another quick fix.
I help startups and growing businesses turn product ideas into SaaS platforms, mobile apps, and business systems that support real users, payments, reporting, and day-to-day operations. Over 8+ years, I've taken products from MVP to production across real estate, marketplaces, booking, fintech, wellness, e-commerce, and internal business tools + WordPress automation build for an MVP that ran 198 hours over a 5-month engagement, and React Native apps where I isolated and fixed recurring crash bugs post-launch. Clients consistently note that I deliver clean, well-tested work and communicate clearly throughout.
That's the stage I specialize in bringing architecture and structure to a product before technical debt slows you down.
What I build
SaaS platforms & startup MVPs
React Native mobile apps (iOS & Android)
Marketplace & booking platforms
Subscription & payment-based products (Stripe, payment gateways)
Admin dashboards & internal business systems
API-driven applications & backend systems (REST, GraphQL, webhooks)
Wix and Wix Studio websites, including CMS, eCommerce, bookings, memberships and custom functionality
Stack: React.js, Next.js, TypeScript, Node.js, NestJS, Express.js, PostgreSQL, MongoDB, Supabase, React Native, AWS, Wix Studio, Velo by Wix, Wix CMS, Wix eCommerce Firebase, Vercel
I focus on long-term maintainability over quick patches, deliver structured and documented code, and think about the product as a whole rather than one ticket at a time because the fastest fix now is often the thing that breaks in six months.
If you're building a SaaS platform, mobile app, or business system and want a developer who thinks about product as much as code, I'd be glad to talk through your project book a 30-min consultation below or send me a message.

I build and maintain custom web applications, internal platforms, and API-connected systems for businesses that need a developer who can own the full delivery — backend, frontend, integrations, and deployment.
My longest client relationship on Upwork is an ongoing ERP platform built in PHP/Laravel — I've delivered 8+ modules including HR, Helpdesk, Firewall Management, Backup Monitoring, and Stock & Project tracking. That kind of work requires understanding a business deeply, not just writing code.
Other recent work includes:
• Freelancing Platform — full application development covering user flows, backend logic, and role-based access.
• Revolut API Integration — backend implementation of payment API with transaction handling and webhook setup.
• Colala Mall — multi-vendor e-commerce platform on the MERN stack with vendor dashboards, order management, and product catalog.
• Tercescrow — gift card and bill payment platform built with Laravel and React Native, integrated with payment gateways.
• Fitness SaaS — social networking, live streaming, trainer monetization, and subscription management in one platform.
• Client Portal & Web Tools — ongoing web application work for an Australian tech company across multiple modules and system integrations.
What I work on:
• Custom web applications and internal tools: admin panels, dashboards, multi-role access, business workflows, and reporting systems.
• API integrations: payment gateways (Stripe, Revolut), third-party services, REST APIs, and webhook handling.
• ERP and platform modules: building on existing codebases, extending functionality, and maintaining production systems.
• Mobile-connected backends: Node.js and Laravel APIs powering React Native applications.
• AI feature integration: OpenAI and other AI services embedded into existing products.
• Deployment and infrastructure: Docker, AWS, DigitalOcean, NGINX, CI/CD.
Stack: Laravel, PHP, Node.js, React, React Native, MySQL, PostgreSQL, REST APIs, Docker, AWS.
I work best when the project has real business logic behind it — existing systems to extend, integrations to build, or platforms that need to keep working while new features are added. I read the codebase before I write a line, and I confirm scope before I start so delivery stays predictable.
Tell me what you're building or where your application is stuck — and I'll give you a straight answer on what it takes.
Integrated systems rarely break on the first successful API call. They break three weeks later: a failed Shopify webhook, an ERP order that never synced, a CRM contact missing from the pipeline, or POS inventory that no longer matches the store.
I build and fix the middleware/API layer behind those systems.
My strongest work is around Shopify, ERP, CRM, POS, and Laravel-based backend systems where product data, orders, inventory, customers, payments, and reporting all need to stay aligned.
What I usually handle:
- Shopify / Shopify Plus integrations and custom commerce workflows
- ERP and CRM syncs: Acumatica, Salesforce, Zoho, HubSpot, SAP-style systems
- POS and inventory workflows: Clover, store operations, loyalty, order flows
- Laravel/PHP middleware, APIs, webhooks, queues, cron jobs, retries, and logs
- Admin dashboards, reporting panels, and operational data models
- Production debugging where the issue is hidden across multiple systems
Relevant background:
- Built and supported systems handling 24k+ products, 3M+ users, and 2,000+ locations
- Led technical delivery across teams of 20+
- Worked across Shopify, Shopify Plus, Magento, BigCommerce, Acumatica, Salesforce, Zoho, Clover POS, Square POS, Laravel, REST/GraphQL APIs, PostgreSQL, MySQL, AWS, Firebase, WordPress, Stripe and other payment systems
I also take on SaaS MVPs and React Native app work when the project depends on backend architecture, integrations, subscriptions, analytics, or production stability.
If your store, ERP, CRM, POS, or internal dashboard is held together by fragile syncs and unclear data flow, I can help trace where it breaks and make the system reliable.
