MVPs, SaaS and web apps, backend APIs, AI features and subscription billing, built with tests and handed over properly.
Services in Custom Software Development
MVP Build
I build the first working version of your product: one web app with the core flow, login, an admin and a production deploy. It’s for founders who have a scope and want a senior engineer, not an agency. From $3,900 ($3,000 founding), delivered in monthly phases over about 3 to 5 months. Start with a Discovery Sprint.
SaaS & Web Apps
I add features and modules to Laravel and Vue/Nuxt web apps, or build new ones. It’s for SaaS founders and agencies who need a senior developer for a defined piece of work. From $780 ($600 founding) for a feature, typically 2–4 weeks, fixed scope. Email me what you need and your stack versions.
Backend APIs
I build backend APIs in Go or Python: documented endpoints, authentication, background jobs, tests and a Docker image ready to deploy. It’s for startups and agencies that need a reliable service behind their app. From $1,300 ($1,000 founding) for up to 10 endpoints, about 3–4 weeks. Email me what the API must do.
AI Features & RAG
I add AI features to working products: LLM features with checked output, vision and document extraction, and answers grounded in your own documents (RAG) with citations. It’s for small teams who want AI that is tested, not a demo. From $1,600 ($1,200 founding) for one feature, about 3–4 weeks. You pay model costs directly.
Subscription Billing
I set up Stripe subscription billing in your app: plans, checkout, the customer portal, trials, and webhooks that keep your app and Stripe in step. It’s for SaaS founders who want billing done once and done right. From $910 ($700 founding), about 2–3 weeks. Your Stripe account stays yours.
