OSKI Solutions designs, builds and runs web platforms, internal systems and AI integrations for companies across the US and Europe. A dedicated team in 2–4 weeks, a fixed estimate before we write code, and every line reviewed by a senior engineer.
We take on the whole lifecycle or any part of it: new platforms, legacy rebuilds, AI features inside existing products, and the cloud and support that keep them running.
Custom products and internal systems designed for the way your business actually works.
Keep what you have fast, secure and current, and move it to infrastructure that scales.
The disciplines that make software usable and keep it that way after launch.
A few of the 28 client projects we have documented. Each metric below comes from the project itself.
An in-platform assistant for Lokad's supply-chain software that answers questions, remembers context and generates executable Envision code, verified against the real engine before it reaches the user.
The university's public ecosystem for applicants, students and faculty: Lucene search with 10+ dedicated search pages, 15,000+ staff profiles synced daily, and a staged Azure-to-AWS migration while the site stayed live.
Catalog, road tests and ads on Umbraco 15 and .NET 9, with ~100K items migrated from a legacy CRM and WCAG accessibility support.
Reusable multi-site architecture, Okta SSO, Eloqua marketing forms and fully automated Azure deployments, so editors publish without developers.
Each product is linked once to its 1688 supplier. After that the platform buys, tracks and bills every order on its own, for a Hong Kong dropshipping operator.
Every engineer at OSKI pairs with AI tooling every day. It makes the boring parts fast. It does not make the decisions, and it never ships unreviewed.
The parts of software that decide whether it works for your business.
The parts that used to eat weeks of senior time without adding judgment.
We map your goals, constraints and existing systems, then return a scoped proposal with architecture, risks and a price.
1–2 weeksA named lead, engineers matched to your stack, and working agreements on demos, access and communication.
team in 2–4 weeksTwo-week sprints, a demo every week, CI/CD from day one. You see working software, not status reports.
weekly demosDeployment to your cloud or ours, monitoring, documentation and a support plan so the system keeps earning.
ongoing supportSame engineers and the same review standards in every model. What changes is who manages the work and how it is billed.
You bring the outcome, we own the delivery: scope, team, timeline and launch.
A full cross-functional team that works only on your product and grows with it.
Senior .NET, Umbraco, React or QA engineers join your team and follow your process.
We design, build and support under your brand. Your client works with you, not with us.
We have built on Umbraco, the leading .NET content management system, for more than 10 years, and have moved client sites across major releases, such as Jongeneel from Umbraco 8 to 17. That depth is why we take on complex migrations, and why we publish the tooling we build along the way.
New builds, upgrades of older Umbraco sites to the current version, multi-site setups and custom editor tools.
Everyone who works on your project is an OSKI employee you can meet on the first call. Most of our engineers have been with us for years, and several clients have been too.

Seven verified reviews, with quality, schedule, cost and willingness to refer all rated 5.0. The quotes below are taken from those reviews.
This is a team of engineers who obviously like what they are doing.
Their communication skills, speed of development, and cost were incredible.
What stood out most was their commitment to delivering a functional and reliable solution, no matter the challenges.
They maintained reliability without needing constant oversight, which made the collaboration efficient.
The project team demonstrated a high level of commitment.
They answered for all our questions and were constantly in touch with us.
We have shipped software in each of these sectors, so we arrive knowing the integrations, regulations and failure modes.
NetSuite integrates through REST or SOAP web services, RESTlets, SuiteScript, CSV import, marketplace connectors and iPaaS. We compare them by fit, limits and price, list where syncs break and show what a custom integration costs.
Shopify connects to NetSuite through Oracle's NetSuite Connector, Celigo's integration app, other apps or a custom build. We compare what each syncs and costs, list the failure points (variants, tax, discounts, refunds, payouts) and price a custom build.
The best CRM for events depends on whether you sell services to one client or run events for thousands of attendees. We compare six options for planners, venues and conference organizers by how they handle clients, attendees, sponsors and integrations.

Contact usWe design, build and run custom software: web platforms and portals, internal systems such as ERP and CRM, mobile and desktop apps, AI and LLM integrations, and the cloud infrastructure underneath on AWS, Azure and Google Cloud. Our core stack is .NET, Umbraco, React, Vue and Angular.
Discovery takes one to two weeks and ends with a fixed estimate. A dedicated team is usually in place within 2–4 weeks of the first call. For urgent rescue work on a stalled project we can start a senior engineer sooner.
Engineers use AI tooling for boilerplate, tests, documentation and migrations, which is where most of the 3× speed-up comes from. Architecture, business logic, security and review stay with people, and every line shipped is reviewed by a senior engineer. We work inside your repositories and policies, and can run fully on your infrastructure if required.
Most engagements run on a fixed-scope estimate or a monthly dedicated-team fee. Project sizes in our Clutch reviews range from $10K–$49K for focused builds to $50K–$199K for multi-year platforms. You get a written estimate after discovery, and scope changes are agreed with you before work on them starts.
