What I Build
Five core services,
all production-focused.
I don't build demos. Every system I ship is designed to run in production and generate measurable results.
Voice AI Systems
AI calling agents that handle real conversations at scale — inbound support, outbound prospecting, and appointment automation running 24/7.
- Inbound & outbound calling agents
- Appointment booking & lead qualification
- Natural multi-turn conversations

- Scalable API architecture
- Deployment & DevOps setup
Automation & Backend
Eliminate bottlenecks. Connect your systems with intelligent workflows — from REST APIs to multi-step AI pipelines.
- FastAPI / Django API development
- n8n workflow automation
- Multi-system AI integrations
- Data pipeline engineering
- Performance optimization
Cloud & Infrastructure
Scalable, cost-optimized cloud deployments built for reliability. Containerized, monitored, and CI/CD ready from day one.
- AWS architecture & deployments

Real production systems. Real business outcomes. Not case study theater.
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.
Results
Monthly Revenue
client now generates
Automated
zero manual calling
Operation
always active
Fastyr.ai
AI Systems Architect
“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.
Results
More Calls/Day
200 → 1,200 daily
Completion Rate
up from 15%
ROI Increase
vs. manual ops
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.
Simz.com
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.
Hyperstack
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.
GPU Utilization
Real-time usage per instance
Cost Per Hour
Granular per-instance billing
Spend Analytics
Total infrastructure cost
Live Dashboards
Operational visibility
Tech Stack
Built with the right tools
for every layer of the stack.
