Selected Work
A curated selection of projects across enterprise, healthcare, cloud, and AI.
Medical Waste Compliance Tracking
Healthcare web application for viewing and tracking medical waste manifests for regulatory compliance. Comprehensive document management for mail-in and pickup services.
Thousands of healthcare facilities — hospitals, veterinary offices, dental practices, and more. Replaced manual manifest distribution and an antiquated legacy portal with a modern cloud application featuring self-service document retrieval, automated export scheduling, pickup calendars, and a reporting suite. Customers report faster compliance documentation and reduced time obtaining proof-of-destruction manifests.

Proprietary Payroll Management System
Payroll solution aggregating data from contact centers, time clocks, and supervisor systems. Intelligent data normalization and dual-interface design for employees and administrators.
500+ employees across multiple sites and time tracking systems. Unified data collection from disparate sources with consistent business rules and a multi-tier approval workflow replacing paper-based signatures. Detected and eliminated >$1M in annual wasted wages from incorrect time collection, invalid blanket approvals, and over-corrections. Reduced weekly payroll processing from 3 days to 2 hours, with real-time timesheet visibility for employees.

Next-Generation Contact Center Interface
Modern replacement for legacy contact center systems with VOIP integration, customizable screen layouts, and dynamic scripting. Bridges legacy TCP/IP with modern API-based solutions.
1,800 agent seats at peak capacity. Replaced an antiquated FoxPro application with a modern interface featuring built-in script authoring, drag-and-drop field management, and advanced time/status tracking with automated penalty rules. Gave supervisors real-time KPI dashboards and team management tools. The system’s rapid customizability allowed the client to stay ahead of competitors by responding quickly to Fortune 1000 client requirements.

AI-Powered Data Cleaning & Matching
Data processing solution using AI for intelligent normalization and issue identification. Features custom MCP server integration for interaction with proprietary client data systems.
Took business operating hours stored in wildly inconsistent formats — "open Tuesdays after 1pm", "MF 9-9", and thousands of other variations — and used AI to normalize them into a uniform structure. A second phase integrated external APIs to fill gaps where internal data was missing. Result: 96% accurate and consistent records, up from just 15%.

What We Do
Full-service engineering — from greenfield builds to legacy rescue, with AI-accelerated delivery at every step.
build new
Full-Stack Development
End-to-end web applications with React, Node.js, Python, and .NET. From frontend to backend, we build scalable, maintainable solutions.
Mobile Development
Native and cross-platform mobile applications for iOS and Android using React Native, Flutter, and platform-native toolchains.
API Development
RESTful APIs, GraphQL endpoints, third-party integrations, and microservices architecture from design through documentation.
modernize & integrate
Legacy Modernization
Strategic migrations, legacy system maintenance, and modernization. We find the most cost-effective path to optimal outcomes.
Cloud Architecture
Scalable cloud solutions on AWS, Azure, and Google Cloud. Infrastructure as code, containerization, and cloud-native development.
Custom Stacks
Don't see your preferred technology? We adapt to your environment and learn your stack to deliver the right solution.
intelligence & assurance
AI & Intelligent Systems
LLM integrations, agentic workflows, MCP servers, and RAG pipelines engineered for production — not demos. Need data privacy? Fully offline inference or your own API keys.
Auth, Security & Compliance
Enterprise authentication, authorization, and compliance solutions. Experience building for regulated industries including healthcare and government, where security isn't optional.
SEO & Performance
Technical SEO optimization, Core Web Vitals tuning, and performance engineering to maximize your digital presence.
How We Work
AI-accelerated where it helps, senior-reviewed everywhere. Every engagement gets the same engineer from first call to production.
Agentic AI Development
We use agentic coding tools daily — and 16 years of production judgment to direct them. Meaningfully faster on greenfield builds, with review rigor AI alone can't provide.
Quality Through Oversight
Every line of AI-generated code is reviewed by experienced engineers. We combine speed with the rigor that production systems demand.
Collaborative Partnership
We work alongside your team to understand business context and deliver solutions aligned with your strategic objectives.
Legacy System Expertise
With 16+ years of experience, we excel at maintaining, modernizing, and migrating legacy systems—always finding the most cost-effective path forward.
AI-Native Development Workflow
We use agentic AI coding tools daily to deliver faster without compromising quality. Every output is reviewed by experienced engineers.
engineering judgment
Anyone can generate code. The value is in knowing what to build, how it should fit together, and what will break at scale. That's what 16 years of production experience brings to every project.
your data stays yours
Need AI assistance without cloud exposure? We offer fully offline inference using local models, or operate under your own API keys. Your code and data never leave your control.
ai on your terms
Full AI acceleration, AI under your data-governance rules, or none at all — we deliver the same way. Offline local models and client-owned API keys are standing offers, not special requests.

About CallSoft
CallSoft brings 16 years of hands-on engineering across enterprise, healthcare, and government systems. We operate lean by design — pairing deep domain expertise with AI-accelerated workflows to deliver at the speed of larger teams without the overhead.
Every project gets senior-level attention from engineers who have shipped production systems in regulated industries, complex integrations, and high-availability environments.
CallSoft is deliberately small: the senior engineer you talk to on day one is the engineer who architects, builds, and ships your system. No handoffs to a bench you never met.
Security & IP, by default
NDA before code is shared. Full IP assignment on paid work. Client-owned repositories and infrastructure. AI tooling that runs fully offline or under your API keys. We are used to vendor security questionnaires and regulated-industry constraints from healthcare and government engagements.
What We Build With
Deep expertise across modern frameworks and platforms, enabling robust solutions for any requirement.
Frontend
Backend
Mobile
DevOps & CI/CD
Cloud Platforms
AI & Data
Database
Model-agnostic AI: we deploy frontier and open-weight models — Anthropic, OpenAI, Google, Meta, Mistral, and locally-hosted alternatives — cloud or fully on-prem, matched to your data-governance requirements.
All brand names, logos, and trademarks are the property of their respective owners. CallSoft has no official partnerships or endorsements beyond utilizing their publicly available products and services to deliver solutions for our clients.
