What we build
Core competencies
Full-lifecycle software engineering across six practice areas. Each engagement gets a dedicated team — same people from kickoff to production.
AI engineering
AI-augmented production engineering, prototype-to-production for LLM applications, RAG, agents, custom assistants, and policy-aware AI integration.
Modernize & migrate
Legacy stack migration (Drupal 7, Magento 1, Joomla, classic ASP), bridge engineering, multi-system replatforming, and database modernization.
Operate & maintain
Managed engineering services, DevOps (AWS, GCP, Azure), CI/CD, on-call response, uptime monitoring, backup, and disaster recovery.
Trust, security & quality
Section 508 + WCAG 2.2 AA accessibility audits, application security review, QA & automated testing, HIPAA-aware infrastructure.
Specialty platforms
Drupal (including legacy 7/8), OpenCart multi-store, WordPress with WP Engine, NetSuite, Salesforce, and HubSpot integration.
Past performance
Past performance
Six anchor engagements across our core verticals plus selected supporting projects. Full reference list with named POCs available on request to procurement officers and prime contractors. Reference calls available during procurement evaluation.
Why OST
What sets us apart
Accessibility-first, procurement-ready
Building and testing to Section 508 + WCAG 2.2 AA is our default, not an upcharge.
Bridge engineering for legacy stacks
Drupal 7. Magento 1. Joomla. Classic ASP. Most agencies abandoned these. We keep them performing, secure, and ready for migration on your timeline.
AI-augmented, policy-aware
We use AI dev tools where they speed delivery. We ship without them when your contract or policy says so. Your rules. We follow them.
One vendor for the full lifecycle
Code, servers, analytics, on-call. Single point of contact across build and operate. Reduces coordination overhead vs. splitting work across multiple subs.
