What I can build for you

Each of these comes from work I have done on real products, not from a list of everything I have read about.

SaaS product development: Multi-tenant business applications with per-product plans, shared accounts and the unglamorous parts done properly: roles, billing boundaries, deployment.
CRM and internal tools: Customer records, pipelines, e-signature and email workflows shaped around how your team already works.
Telephony integration: Click-to-call and browser softphones connected to a self-hosted FusionPBX / FreeSWITCH system.
Shipping on shared hosting: Getting real applications running reliably on cPanel and hPanel plans, including cron, mail limits and security headers.
