Areas of expertise

Data and models
AI platforms
Connect data, training and model use, with versions, budgets and recovery.
Security
AI with sensitive data
Permissions, protected storage and output reviewed by people.
Integration
AI in existing systems
Connect databases, applications and telephony in stages, without stopping operations.
Capacity · GPU
Shared GPU
Text and speech models sharing one graphics card, in turn.
Models · LLM · vLLM
Private inference

Speech · WebRTC · Opus · Whisper
Speech operations
Live audio turned into text, from browser to server, with recovery after failures.
Voice agents · WebRTC · Whisper
Real-time voice
Voice agents that listen and answer, with interruptions and measured delay.
Privacy · PII · LLM
PII-safe LLM layer
A barrier that removes CPF, e-mail, phone and names from text before the model.
Industry · SIP · LGPD
Healthcare and emergency
AI for healthcare and emergency-response operations, with telephony and protected clinical data.

6–8 hours a week: Scoped project, monthly contract or part-time. A few projects at a time.

AI in production: what you need beyond the model
A deployment guide for companies: real workloads, APIs, queues, access, monitoring, versions and recovery.
How to size GPUs and AI inference costs
Context, concurrency, queueing and latency: measurement criteria for planning an AI product's infrastructure and costs.
How to prepare AI for sensitive data
Define access, data flows, storage, logs and human review before connecting AI to restricted documents and conversations.
How to connect AI to the systems your company already uses
Plan AI integration with databases, applications and telephony: contracts, action confirmation, queues, recovery and staged deployment.
