Most software projects don't fail because the code was hard.
They fail because the wrong decisions got made in the first two weeks, and someone paid for that later with a rebuild.
That is the part I care about most.
I run Posybl, an AI-native software studio. Along the way, I've built for names like Sony, PepsiCo and Ericsson, as well as founders and small teams who just needed their idea to work.
I don't only write the build. I help you pick the right path before a single workflow is created, so you spend money once instead of twice.
What I build
• SaaS platforms
• Startup MVPs
• Marketplaces
• CRM and ERP systems
• AI-powered apps
• Internal tools
• Client and staff portals
• Booking and scheduling systems
• Inventory platforms
• Dashboards and reporting
• Workflow automation
• Custom web apps that don't fit a template
How I build it
I choose the platform and architecture based on what the product actually needs. My team and I can launch lean, integrate the right services and scale the infrastructure as the product grows:
• Node.js
• Next.js
• PostgreSQL
• Supabase
• Neon
• Xano
• REST and GraphQL APIs
• Stripe and Stripe Connect
• OpenAI and Claude integrations
• Twilio
• Google APIs
• Airtable
• Make(.)com and n8n
So you're not hiring "a generic AI guy". You're hiring someone who can start you lean and move you onto heavier infrastructure the day your growth demands it.
Where I've worked
• Healthcare
• Fintech and financial services
• Construction
• Education
• Logistics
• Property
• Manufacturing, and
• Professional services.
Real projects have included AI education platforms, Financial applications, Compliance and Document Systems, Quoting and Estimating tools, Customer portals, Inventory Management, and End-to-end automation.
What every build gets, by default
Secure. Scalable. Fast on mobile and desktop. Easy to maintain instead of held together with patches. And shaped around how your business actually runs, not around whatever was easiest to code.
How I work
I start with the problem, not the feature list. I'll pressure-test your idea, flag the risks early, recommend an architecture that won't box you in, and build something that can grow with you. A lot of my clients launch a lean Bubble MVP to validate fast, then layer in Node.js, Supabase, Postgres or custom APIs as usage climbs. The goal never changes, software that returns real business value.
Founder with a raw idea, or an established team modernising old systems, either way I'm happy to talk it through. If you want a developer who pairs the technical side with commercial judgement and clear, honest communication, let's have a conversation about what you're building.

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, Laravel, REST/GraphQL APIs, PostgreSQL, MySQL, AWS, Firebase, and 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.

I help teams fix, migrate, and stabilize Supabase/PostgreSQL systems — especially when things are already breaking, inconsistent, or need to scale without risking data loss.
I design and run secure, scalable backend systems for real-world data pipelines, including healthcare EDI (837 → 835), Supabase architectures, and production systems where accuracy, reliability, and data protection are non-negotiable.
I also build and stabilize AI-powered systems, integrating LLM APIs (OpenAI, Claude) into backend workflows where structured data, validation, and consistency matter — not just prototypes, but production-ready systems.
I’ve migrated 50+ standalone databases into a unified PostgreSQL system with zero data loss, handling messy schemas, inconsistent data, and edge cases that typically break systems after deployment.
I currently work in a healthtech environment building and maintaining revenue-critical pipelines, including systems that handle protected health information (PHI) in HIPAA-aware environments. This includes AI-assisted revenue cycle management (RCM) workflows, where structured healthcare data (EDI 837/835) is combined with LLM-driven processing while maintaining strict data integrity and auditability.
⸻
What I specialize in:
* Supabase systems — schema design, RLS, auth, performance, debugging
* Database migration — SQLite, MySQL, legacy systems to PostgreSQL
* Healthcare data pipelines — EDI 837/835 workflows, claims and remittance processing
* Backend stabilization — fixing inconsistent or failing systems
* API integrations and ETL pipelines — ingestion, transformation, validation
* AI systems — LLM integrations, structured outputs, and production-ready workflows
* AI-built apps — fixing, stabilizing, and taking them to production
⸻
Recent work includes:
* Migrated 50+ databases into a unified PostgreSQL system (zero data loss)
* Built and stabilized Supabase-backed systems with scalable architecture
* Designed and maintained healthcare data pipelines (EDI 837 → 835)
* Implemented secure ingestion pipelines (API + validation layers)
* Built AI-assisted RCM workflows combining claims (837) and remittance (835) data with LLM processing
* Implemented validation layers to ensure AI outputs are structured, consistent, and safe for production use
* Fixed and optimized AI-generated applications for production
⸻
I work with sensitive healthcare data where accuracy, security, and reliability are critical, and systems must be designed to handle real-world complexity without failure.
If your Supabase project is breaking, your data needs to be migrated safely, or you’re building an AI-powered system that needs to work reliably in production — I can help you get it stable and production-ready.
