Tech Stack

Providers chosen by workflow, not hype.

I use a provider-agnostic stack across voice AI, LLMs, CRM, automation, data, hosting, payments, analytics, and communications. The right stack depends on cost, latency, reliability, data ownership, and what the operator actually needs to run.

AI Voice

Provider choices for outbound, inbound, qualification, transfer, and call-summary workflows.

VapiVoice agent orchestrationFast voice-agent prototyping with functions and telephony integrations.Retell AIVoice agentsConversational voice deployments where voice quality and call flow tooling matter.Bland AIPhone agentsHigh-volume calling experiments and simple outbound workflows.TwilioTelephonyNumbers, SMS, voice routing, compliance, and call infrastructure.

LLMs

Models selected by task cost, reliability, latency, tool use, and reasoning depth.

OpenAIReasoning and tool useAgents, structured extraction, workflow reasoning, and production assistants.AnthropicLong-context writing and analysisDocument-heavy workflows, support drafting, and careful review tasks.Google GeminiMultimodal AIDocument, image, and multimodal processing workflows.

CRM

Systems of record for contacts, pipelines, ownership, reporting, and follow-up.

Automation

No-code, low-code, and custom integration layers for moving data safely.

Data

Storage, data quality, reporting, and enrichment layers for systems that need trustable inputs.

Analytics

Measurement and monitoring tools for traffic, speed, errors, and funnel decisions.

Payments

Billing, invoice, subscription, and contract-to-payment workflows.

StripePayments and billingCheckout, invoices, subscriptions, and payment webhooks.

Communications

Channels for alerts, reminders, human handoff, and client communication.

DiscordInternal alertsFast team notifications for hot leads, payments, and ops events.ResendTransactional emailLead notifications, confirmations, and product email.WhatsAppDirect messagingHigh-response manual or automated follow-up where appropriate.CalendlyBookingSimple call scheduling with automated confirmation flow.

Stack recommendation

The current website stack is good and does not need a replacement: Next 16, React 19, Tailwind 4, Supabase, Resend, Upstash, Sentry, and Vercel are a solid fit. The improvements are organization, proof media, lazy SDK initialization, route structure, performance checks, and clearer package surfaces.

Want the right providers for your workflow?

Book a build call for implementation, or request a system audit to compare providers before you commit.
