AI / HEALTHCARE / FULL STACK01
Healthcare AI Voice Agent
A portfolio-ready full-stack AI healthcare appointment assistant built to demonstrate conversational scheduling, clean API boundaries, safety-conscious AI behavior, containerized development and cloud-ready architecture.
Problem
Healthcare appointment workflows can be repetitive and fragmented across intake, availability checks and scheduling.
Solution
Designed an AI-assisted scheduling experience with a React interface and FastAPI backend that separates conversation logic from scheduling services.
Engineering
Implemented REST APIs, typed frontend components, automated backend tests, Docker development and CI with an AWS ECS/Fargate-ready deployment structure.
Current Scope
Portfolio demonstration with safe non-diagnostic behavior. Real Cal.com API wiring, voice-provider integration and production PHI controls remain roadmap items.

AI / ERP / ENTERPRISE02
AICO — Artificial Intelligence Computing
Cloud-ready AI-enabled enterprise platform designed to unify core business operations, workflow automation, reporting, analytics and intelligent assistance within a modular ERP architecture.
ProblemBusiness data and workflows are often fragmented across disconnected finance, sales, HR, inventory and operational systems.
SolutionDesigned a unified enterprise platform with shared services, consistent data boundaries and AI-assisted workflows across core ERP domains.
ArchitectureModular-monolith-first design with bounded business domains, REST APIs, centralized security, SQL Server persistence and cloud-ready deployment patterns.
Current ScopeActive architecture and product development. Modules are being implemented incrementally, with service extraction reserved for areas where scale or isolation justifies it.

DATA / BI / ENTERPRISE04
Insurance Reporting & Analytics
Enterprise reporting and analytics framework for non-life insurance operations focused on paid claims, policy, branch, calamity and turnaround-time reporting with reconciliation against a common transactional baseline and agreed business rules.
Problem
Multiple insurance reports must reconcile against a common baseline, with discrepancies introduced by business rules, SQL logic, report filters and inconsistent data interpretation.
Solution
Built a reporting and validation approach covering policy, branch, calamity, paid-claims and TAT views with standardized calculations, reconciliation logic and repeatable validation steps.
Engineering
Used SQL Server queries and stored procedures, Telerik Reporting, reconciliation logic, business-rule validation, data analysis and report optimization to investigate and resolve mismatches.
Business Impact
Improved report consistency and auditability, accelerated discrepancy investigation and provided more reliable operational and management reporting for decision-making.
