Reviews

“We cut release cycles by 30 %.” smartbrain.io dropped a senior Vaadin UI developer into our Spring-based trading portal in 48 hours. He mastered complex Grid renderers, refactored legacy Vaadin Flow code and helped QA automate regression suites—boosting deploy frequency and freeing my core team for strategic work.

CTO

FinVerity Capital

Seamless HIPAA-ready front-end. Our patient portal demanded pixel-perfect Vaadin components and strict security. The smartbrain.io contractor integrated SSO, customised Vaadin Charts, and paired with backend teams in PST. Onboarding was under one sprint, productivity soared, and we avoided four months of recruiting downtime.

Engineering Manager

MedSight Analytics

Real-time dashboards delivered fast. We lacked in-house Vaadin architects for our logistics tracker. smartbrain.io assembled two pre-vetted Vaadin framework experts inside 72 hours, aligning with our microservices stack. They optimised Push scalability and improved UI latency by 22 %, letting us meet an investor demo deadline.

VP of Technology

TransitFlow Systems

Zero friction augmentation. Adding an external Vaadin developer usually risks IP leaks, but smartbrain.io offered airtight NDAs and isolated Git access. The engineer rebuilt complex FormLayout flows, elevated code coverage to 92 %, and coached juniors—accelerating premium calculator launch by two sprints.

Product Owner

ClearPolicy Insurance

Cost-efficient scaling during peak. When enrollment spiked, we added three remote Vaadin coders through smartbrain.io. They slotted into our CI/CD, extended Vaadin Grid filters, and resolved 120 backlog tickets in six weeks. Total spend was 38 % lower than temp agencies.

Healthcare Portals

Healthcare Portals: HIPAA mandates airtight data handling. Vaadin's stateful session model plus smartbrain.io's outstaffed specialists let providers launch EHR front-ends, tele-health scheduling and lab result dashboards fast. Senior Vaadin developers integrate HL7/FHIR APIs, SSO and role-based access while ensuring PHI never touches the client browser—cutting compliance cycles and accelerating patient engagement initiatives.

Logistics & Supply Chain

Logistics & Supply Chain: Fleet managers need live maps and order tracking UIs that refresh thousands of rows without lag. Vaadin’s Push and Grid make that easy, and an outstaffed Hire Vaadin developer from smartbrain.io fine-tunes them for WebSocket scale, ensuring dispatchers see accurate ETAs and warehouse teams pick faster.

Manufacturing MES

Manufacturing MES: Shop-floor terminals demand rugged, browser-based interfaces. Vaadin’s Java-only stack keeps code under one language umbrella. Outstaffed Vaadin pros create OEE dashboards, machine-state widgets and barcode integrations so plant managers gain real-time visibility without commissioning expensive proprietary HMI software.

Telecom OSS/BSS

Telecommunications: Billing portals and service-provisioning consoles require complex data grids and secure session control. Vaadin covers the UI; smartbrain.io’s outstaffed developers wire it to legacy SOAP stacks and modern microservices, helping carriers roll out new plans in weeks instead of quarters.

Energy & Utilities

Energy & Utilities: From SCADA dashboards to consumption analytics, Vaadin enables data-dense screens. Outsourced Vaadin talent optimises Push for field latency, delivers real-time alarm panels and embeds charting libraries so operators respond to anomalies instantly, boosting grid reliability.

Retail & eCommerce

FAQ – Vaadin Staff Augmentation

What is the real cost to hire Vaadin developers versus outstaffing?

When you Hire Vaadin developer talent directly, you shoulder recruiter fees, signing bonuses, payroll taxes, hardware, SaaS licences and the very real risk of a mis-hire. A single senior engineer can exceed $180 k annually before incentives. Outstaffing with smartbrain.io converts that CapEx into pure OpEx: a transparent monthly rate covering salary, benefits, workspace, continuous training and even replacement guarantees. There are no placement fees, no idle-time liability—pause or scale the engagement at the end of any sprint. Companies typically save 25–45 % on total cost of ownership while gaining the flexibility to bring in niche Vaadin UI, Vaadin Flow or Vaadin Fusion skills only when the roadmap demands.

How does smartbrain.io keep our IP safe when we add external Vaadin engineers?

Intellectual property protection sits at the core of our service model. Every outstaffed Vaadin developer signs a dual NDA—one with smartbrain.io and another directly with your entity. Access to repositories is granted through SSO and scoped tokens so you can revoke credentials instantly. We recommend isolated branches plus audit logging for every commit; our engineers are accustomed to this workflow. Source code lives exclusively in your version-control system, never on personal drives. For regulated industries we enable VDI environments with clipboard control, disabling local copy. Finally, smartbrain.io carries full professional indemnity and cyber-liability coverage for an additional compliance layer. The result: Fortune-500-grade IP security without the bureaucratic drag.

Can your Vaadin developers work in our time zone?

Yes. Our talent network spans North and South America, Europe and APAC, allowing us to align 4–6 core-overlap hours with nearly any location. During onboarding we agree on stand-up times, code-review windows and escalation paths to guarantee real-time collaboration. Should your roadmap require 24/7 coverage, we assemble a follow-the-sun squad so pull requests never idle overnight. You keep the agility of an in-house team while tapping truly global Vaadin expertise.

What contract terms are offered for Vaadin staff augmentation?

Engagements start at one month with no long-term lock-in. Billing is monthly, net-15, and you may scale team size up or down at the close of any sprint. Need a two-week trial? We offer it free, confident our Vaadin developers will prove value fast. All agreements comply with US and EU labour regulations, simplifying vendor-risk assessments for your legal team.

How are Vaadin candidates vetted before we see their CV?

Each applicant passes a three-stage filter: automated coding tests focused on Vaadin Flow, Java 17 and reactive patterns; live pair-programming with a senior Vaadin architect; and a culture-fit interview led by a former CTO. Only 3 % reach our client bench. You receive skill-matrix reports, reference checks and a recorded code session so your decision is data-driven, not gut-feeling.

What if the assigned developer isn’t the right fit?

We provide a no-questions-asked replacement guarantee. Notify us within the first 14 days and we will swap the engineer at zero cost, typically in under 48 hours. Because every Hire Vaadin developer in our network shares a common onboarding playbook, the transition is seamless—no lost velocity, no duplicated ramp-up time.

How quickly can a Vaadin developer start on my project?

Standard lead time is 48–72 hours after you approve a profile. Paperwork is e-signed via DocuSign, the engineer receives access credentials, and a kick-off call is scheduled to align sprint goals. Emergencies happen—if production is on fire we can begin in as little as one business day, drawing from our ready-bench of pre-cleared Vaadin pros.
