I work across interface design, application code, APIs, and data models. You have one engineer who can follow a feature through the whole system, clarify the tradeoffs, and work with your team to deliver it.

• React and Next.js interfaces built around user workflows
• NestJS or Java/Spring Boot APIs and application logic
• Database models, authentication, and role-based access
• Deployment setup and documentation for continued development

The checkout is one part of the business. I connect the storefront to product, inventory, and order management, then carry the work through payments, customer communication, deployment, and handover.

• Customer storefront and administration portal
• Product, inventory, and order management
• Card payments, cash on delivery, webhooks, and refunds
• Order tracking, receipts, and transactional email

I integrate AI services into usable applications, with validation, progress states, and controls around access and usage. My StyleFrame AI work brings image generation together with shopper journeys and retailer operations.

• AI API integration and asynchronous job processing
• Input validation, progress, and result states
• Tenant isolation and role-based access
• Usage analytics, credit accounting, and spending limits

I connect development work to delivery with deployment pipelines, separate environments, and clear documentation. The handover covers how the application is configured, deployed, and operated.

• Docker services and GitHub Actions deployment workflows
• Development, staging, and production configuration
• Custom domains and environment setup
• Architecture, deployment, and administration documentation

I turn requirements and Figma designs into reusable interfaces, with clear states for loading, validation, and user actions.

• React
• Next.js
• Redux
• Figma
• Interface design

I build the APIs and application logic behind the interface, including authentication, role-based access, and integrations with external services.

• NestJS
• Node.js
• Express.js
• Spring Boot
• Jakarta EE
• Flask

I connect data models to application workflows, from product and order records to transactions, tenant boundaries, and session storage.

• SQL
• PostgreSQL
• MySQL
• MongoDB
• Redis
• Prisma
• Hibernate

My delivery work includes Docker services, GitHub Actions workflows, separate environments, and documented handover. My wider toolkit also includes AWS, Azure, and Google Cloud.

• Docker
• GitHub Actions
• AWS
• Azure
• GCP
• Git & GitHub
• Linux

TypeScript and JavaScript across web applications, Java for Spring Boot systems, and Python for additional backend and tooling work.

• TypeScript
• JavaScript
• Java
• Python

Project-specific experience includes AI image generation, a Flutter mobile foundation, and integration of 3D assets and smart-contract events. StyleFrame AI consumer mobile features remain in development.

• fal.ai
• Flutter
• Dart
• React Native
• Three.js
• Babylon.js
• WebGL
• Wagmi
• Solidity (basic)

We discuss your product, users, and current constraints, then work out whether my experience fits what you need.

You receive a written scope, delivery milestones, and an estimate. We agree on responsibilities and priorities before development begins.

We work in reviewable milestones, with progress updates and demonstrations on an agreed schedule. Questions and tradeoffs are discussed as the work develops.

You receive the code, deployment configuration, and operating documentation. We agree on any ongoing support so the next steps are clear.
