What I Build

Five core services,
all production-focused.

Real production systems. Real business outcomes. Not case study theater.

Voice AIAutomationCalling System

SimpleTalk.ai

Lead AI Systems Engineer

Turned a manual calling operation into an AI-powered revenue machine.

Challenge

The client was running a call-heavy sales operation entirely on human agents — slow, inconsistent, and impossible to scale. Every lead required manual follow-up, causing massive drop-off and capped revenue potential.

Solution

Built a full-stack AI calling system with natural conversation flows, real-time objection handling, appointment booking, and deep CRM integration. The system runs 24/7 without human intervention.

6x call volume. 5x completion rate. Built in weeks.

Challenge

Capped at 200 calls/day with a 15% completion rate — the business couldn't scale without hiring dozens more agents. Cost-per-acquisition was unsustainable.

Solution

Engineered an AI-powered outbound dialing system with smart retry logic, optimal timing algorithms, conversational AI, and real-time performance analytics. Completely replaced the manual process.

Accelerado.ai

Backend Engineer & AI Integration

Problem

Complex business workflows relied on manual coordination, creating bottlenecks and limiting throughput as the platform scaled.

Solution

Architected scalable backend infrastructure with AI-powered automation workflows designed for high-throughput, reliable operations.

Measurable reduction in manual overhead with reliable automation running at scale.

Voice AI & Automation Engineer

Problem

Manual lead qualification and slow response times were losing prospects before they could convert — the team couldn't keep up with inbound volume.

Solution

Built voice AI pipelines for automated lead engagement with deep CRM sync, giving the team full funnel visibility without manual work.

24/7 automated inbound and outbound lead engagement with zero manual intervention.

InfraHub Portal

Full-Stack Engineer & System Architect

Problem

Tracking GPU usage and infrastructure costs across the organization was fragmented, slow, and made data-driven decisions nearly impossible.

Solution

Designed and built the full InfraHub system end-to-end — real-time GPU dashboards, per-hour billing analytics, and total spend visibility.

Instant infrastructure visibility enabled faster cost decisions and measurable spend optimization.
