Project details
Hi! I’m a C#/.NET developer with 5+ years of experience and deep expertise in PayPal and Stripe integrations. I’ve delivered end-to-end payment solutions tailored to complex business needs.
One of my key projects was building a full e-commerce platform similar to Freelancer, where I implemented:
Customer onboarding for PayPal integration
Milestone and fixed-price project payments
Payouts for freelancers
Reference Transactions for automatic client billing
Recurring payments for subscription plans
I don’t just write APIs — I focus on understanding your business and delivering the right solution to automate and streamline your payment workflows.

They hire me because they have a product that needs to be built, a platform that's becoming difficult to scale, or a production problem that nobody has been able to solve properly. My job is to understand the problem first, then design a solution that's practical, maintainable, and built for the long term.
My work is focused on Healthcare Software and SaaS applications.
I've worked with healthcare startups building Patient Portals, Pharmacy Management Systems, Telemedicine platforms, EHR workflows, and Healthcare APIs. I've also worked on enterprise SaaS products that support multi-tenancy, role-based access control, subscription management, billing, authentication, and large-scale integrations.
Healthcare software brings a different set of challenges. Security, auditability, compliance requirements, and integrations aren't features that can be added later. They need to be considered from the beginning. The applications I've worked on follow HIPAA practices, and I've built integrations with Epic and FHIR to support secure healthcare workflows.
On the SaaS side, I've designed and developed applications that serve more than 150,000 active users across multiple tenants while handling over 500,000 requests each day. Those systems need to remain reliable as they grow, which means making good architectural decisions early instead of constantly rewriting features later.
I'm comfortable joining a project at any stage. Sometimes that means building a new product from scratch. Sometimes it means reviewing an existing codebase, identifying what's causing problems, and improving it without disrupting the business. I've worked on legacy .NET applications, modern cloud-native platforms, third-party integrations, and systems where reliability matters because downtime has a direct business impact.
Recently I've worked on projects including:
* A Pharmacy Management System with automated invoicing, notifications, reporting, and operational workflows.
* An AI-assisted prescription processing system that uses OCR and Azure OpenAI to extract prescription information, generate structured data with GPT-4, and reduce manual data entry while keeping pharmacy staff in control of the review process.
* An Open Banking integration for an Icelandic financial platform using PSD2 APIs, OAuth 2.0, and mutual TLS.
* A multi-stakeholder logistics platform where I planned the architecture, estimated delivery, and helped define the implementation roadmap before development began.
* An AI-assisted lead management platform built with Next.js, Supabase, and Claude to score, prioritize, and manage incoming leads.
Most of my work involves:
* Healthcare Software Development
* SaaS Application Development
* ASP.NET Core and C#
* Next.js and React
* REST API Development
* PostgreSQL, SQL Server, and Supabase
* Microsoft Azure and Docker
* FHIR and Epic Integrations
* Authentication, Authorization, and RBAC
* Azure OpenAI and AI Integrations
* Performance Optimization
* Third-Party API Integrations
I prefer working with founders, CTOs, and engineering teams where technical decisions have a direct impact on the product. I ask questions early, communicate risks before they become problems, and break work into clear milestones so everyone knows what's being built and why.
If you're building a healthcare platform, a SaaS product, or modernizing an existing application, I'm happy to discuss the problem you're trying to solve and whether I'm the right person to help.
