Custom Software Development
Off-the-shelf tools bend your business to their limits. I build custom Twilio and AI-powered software around the way you actually work.
Generic platforms get you to 80%. The expensive 20% is custom.
I design and build custom software for communication-heavy businesses: Twilio-based messaging and voice systems, AI integrations, and the APIs that connect them to the tools you already run. You own the code, the data, and the roadmap.
Custom Twilio development
Messaging and voice systems built on Twilio to your exact requirements: campaign platforms, call routing, WhatsApp flows, and A2P-compliant SMS at scale.
Custom AI integrations
LLM-powered features embedded in your real workflows: WhatsApp assistants, voice agents, document processing, and automations with human handoff where it matters.
Communication platforms
Custom communication software that unifies SMS, WhatsApp, voice, and email into one system your team controls, with the reporting your operation needs.
Custom APIs and integrations
RESTful APIs and integrations that connect your CRM, billing, calendars, and internal tools so data flows without manual re-entry.
Internal tools and dashboards
Operator dashboards, admin panels, and reporting tools tailored to how your team works, replacing the spreadsheet glue that breaks under volume.
Modernization and automation
I take over legacy systems, stabilize them, and automate the manual steps around them, so the software your business depends on stops being a risk.
Discovery and architecture
We map the workflows that need software, define the scope that pays for itself first, and design an architecture that fits your existing stack instead of replacing it.
Development and integrations
I build the system with Laravel, Python, and the APIs it needs to talk to: Twilio, WhatsApp Business, OpenAI, your CRM. Short cycles, working software at every step.
Launch and iteration
Deployment, monitoring, and documentation your team can maintain. Then we iterate on what production data says, not on assumptions.
