What I Do

AI Agents & MCP

Custom agents, agent tools and skills, MCP servers and connectors. Make business systems usable by agents through clear tool interfaces and configurable permissions.

Custom agentsMCPTools & skills

Real-Time Voice AI

Real-time voice agents with custom voice activity detection (VAD), speech recognition and speech synthesis.

Real-time voiceCustom VADSTT / TTS

RAG & Multimodal AI

Retrieval grounded in business data and documents, including a document-vectorization project, plus speech and image-generation integrations.

RAGDocument vectorizationMultimodal

Production Automation

Configurable workflows with triggers, conditions, actions, state, idempotency, retries and audit trails. Use deterministic execution where the process is known.

Workflow orchestrationState & retriesAudit trails

APIs & Integrations

Connect messaging, CRM, marketing and cloud services with reliable APIs, OAuth2, token management, webhooks and replaceable connectors.

REST APIsOAuth210+ integrations

Backend & Azure Architecture

Production backend services, multi-tenant systems and pub/sub. C#/.NET, TypeScript/Node.js and Python, with Azure, SQL Server and Cosmos DB.

Selected Projects

WhatsApp AI Automation Platform & MCP Control Plane

Production multi-tenant platform orchestrating customer workflows through WhatsApp and connected business services; the platform serves several hundred active clients daily.

2023-present

Custom SEO & Social-Media Agents

Implemented agent-supporting tools, skills, integrations and tests for agents that analyze clients and competitors, suggest blog and social-media content, connect to a CMS and support publication workflows.

Agent Tools, Skills & Retrieval Work

Turned multi-step application tasks into agent-callable tools by reverse-engineering application behavior, then refined tools using available logs.

Selected work

Production Integrations & Workflow Reliability

Built modular production connectors for Google, Meta, Salesforce, Azure AI and Seats.io, including OAuth2, automatic token refresh, webhooks, retries and circuit breakers.

How I Work

Agent engineering: Translate domain knowledge into agent-usable tools and skills, separate deterministic steps from variable reasoning, and test behavior with positive and negative examples.
Production mindset: Bring AI features into real workflows with integrations, configurable permissions, operational visibility and dependable backend services.
Real World Problem Solving: Start with the actual business problem, find its root cause and deliver a simple, logical solution that is practical to operate and maintain.
