What We Do

Eight service verticals built for mission-critical environments

Every engagement is staffed with vetted, top-tier consultants and delivered under our ISO-certified quality, security, and service management systems.

Application Services

Custom application design, development, modernization, and ongoing support across Java/J2EE, .NET, Python, PHP, FastAPI, and Next.js—built to integrate with your existing systems and ready for AI augmentation.

Cybersecurity

Risk assessments, vulnerability management, and compliance support aligned to ISO/IEC 27001:2013—with proven experience securing healthcare and financial systems.

Database Support

Administration, performance tuning, migration, and 24/7 support across Oracle, SQL Server, MySQL, and NoSQL platforms—plus ETL with Informatica and SAP Data Services.

Mainframe Rehosting

Lift-and-shift legacy COBOL, JCL, VSAM, and DB2 workloads to modern Linux infrastructure with TmaxSoft OpenFrame—scaling to 100K+ MIPS with no rewrite and no disruption to end users.

Open Source Solutions

Architecture and development with open-source frameworks—including LangChain, LangGraph, ReAct agent graphs, FastAPI, Next.js, and local LLM inference with Gemma 4 and Ollama—reducing licensing costs while increasing flexibility and portability.

Product Development

End-to-end product engineering—from requirements and UX through delivery and support—for government and commercial clients who need custom software built to last.

Professional Consulting

Senior technology advisors who augment your team—providing architecture guidance, technical leadership, and hands-on delivery for complex modernization initiatives.

QA & Testing

Manual and automated testing—functional, regression, performance, and security—ensuring releases meet ISO 9001:2015 quality standards before they reach production.

Delivery Discipline

Project & Program Management

PMI-Aligned Governance

Every engagement is governed by structured project management practices—scope, schedule, budget, risk, and quality tracked and reported throughout the project lifecycle.

ISO/IEC 20000-1:2011 Service Management

Our certified IT service management system standardizes incident, change, and release management—giving program managers clear visibility and predictable outcomes.
