IT Services for Organizations of Every Size

PS3G’s IT services cover the whole life of a system: consulting to decide what to build, engineering to build it, testing to prove it, managed services to run it, and governance to keep it compliant. You can buy one piece or the whole chain from one IT services company. A founder, a growing company and a department inside a large organization get the same engineers; only the scope and the paperwork differ.

This page lists every service we offer, from software development services to governance, grouped by the problem you are trying to solve. Each link goes to a page with deliverables, process, stack and engagement options.

How our services fit together

Most software problems move through five stages, and each has a service line behind it.

Build

• Website development: marketing sites and content-driven websites, usually on WordPress, built to be edited by your team and maintained after launch. Also see WordPress development, website redesign and e-commerce development.
• Web application development: portals, dashboards and line-of-business applications on React, Angular, Node.js, Python or .NET, with API development and integration to the systems you already run.
• Mobile app development: native iOS and Android, Flutter and React Native, through store submission and the releases that follow.
• .NET development: ASP.NET Core, Blazor, Entity Framework, SQL Server and Azure, plus the wider Microsoft technology stack of Dynamics, SharePoint and Power Platform.
• Custom software development and maintenance: discovery, design, delivery and the maintenance plan that keeps the software working after the project ends.
• Healthcare software development: HIPAA-by-design apps, portals, telehealth and EHR integrations from a team that runs its own EHR platform.

Languages and platforms

Our engineers work across the major languages, frameworks and clouds. We pick the stack that fits your team, your hiring plans and what you already run, and we say why in the proposal.

• Node.js and TypeScript: APIs, real-time services and back ends for web and mobile products.
• React and Next.js: fast, maintainable front ends and single-page applications.
• Angular: enterprise front ends and upgrades from older AngularJS code.
• Python: Django and FastAPI back ends, data pipelines and AI and machine-learning work.
• Java: Spring Boot services and the upkeep of established enterprise systems.
• PHP and Laravel: web applications, APIs and WordPress or WooCommerce extensions.
• .NET and Azure: ASP.NET Core, Blazor, C#, SQL Server and Azure, including migrations off older .NET Framework applications.
• Mobile: Swift, Kotlin, Flutter and React Native, depending on the product.
• Desktop: Windows and cross-platform desktop applications, from new line-of-business tools to modernizing older desktop software.

Modernize

• Application modernization: rehost, replatform, refactor or rebuild, chosen per application rather than by slogan.
• .NET migration and modernization: moving .NET Framework, WebForms and classic ASP applications to current .NET with a tested migration path.
• Cloud migration: inventory, migration plan, cutover and cost control on Azure, AWS or Google Cloud, with minimal disruption to the people using the system.
• DevOps: pipelines, infrastructure as code, monitoring and release practices that make the next change cheaper than the last.

Data and AI

• Data governance: policies, roles, data quality and classification, with a practical 90-day start instead of a binder.
• Data engineering and analytics: warehouses, ETL and dashboards, described on our solutions pages, plus Power BI consulting for reporting.
• AI consulting: readiness assessment, use-case selection and a proof of concept designed to reach production.
• AI development: custom models, retrieval-augmented features and integrations with your existing applications.
• AI agents and chatbots: assistants that answer from your documents and act inside your systems, with guardrails and logging.

Protect and comply

• Cybersecurity: risk assessment, IT audit, policies and training, described under information security.
• IT compliance consulting: readiness for customer questionnaires and frameworks, including HIPAA, SOC 2 and CMMC.
• AI governance: AI policy, inventory, risk assessment and alignment with the NIST AI RMF and ISO 42001, sized to your organization.

Run

• Managed professional services: we run the application, the cloud environment or the whole stack under a defined SLA, with US and India coverage.
• Staff augmentation: PS3G engineers inside your team, monthly, scaled up or down as the work changes.
• Software testing: functional, automation, performance, security, compatibility and mobile testing from the testing center of excellence.
• Website maintenance and support: updates, backups, security patches and content changes on a monthly plan.

Engagement models

Model	What you get	Fits best when
Fixed-scope project	A defined deliverable at a fixed-scope quote	The outcome is clear and you want a predictable budget
Dedicated team or staff augmentation	Named engineers on a monthly basis, scaled up or down	The backlog keeps moving and you want continuity
Managed services	We run the system under a defined SLA	You want the outcome without running the operation
Advisory	Assessment, roadmap or fractional CTO time	You need decisions before you need code

How we start is the same in every model: a first conversation, a short assessment, then a written proposal. Book the call and tell us what you are trying to do.

If you are not sure where to start

Many conversations about IT consulting services, or about business IT services in general, begin with a symptom rather than a request: a spreadsheet that has become a system, an application nobody wants to touch, a customer asking for a security questionnaire, or an AI pilot that never reached production. Start with technology consulting. A short assessment turns the symptom into a scoped piece of work, and you keep the write-up whether or not we do the build.
