Build with us
like you'd build in-house.

Hire Flutter developers who join your team, your repo, and your standups — backed by a 66-engineer Flutter organization that ships pixel-perfect Material 3 + Cupertino apps from a single Dart codebase — for delivery startups, fintechs running iOS+Android+Web from one team, and B2B internal tools that need fast iteration.

On your team, day 1

Engineers join your Slack, your Jira, your sprint board. No layers, no PM filter — they pair with your Flutter team like senior in-house hires.

Direct git access

They open PRs straight into your monorepo. You see every Dart file, every widget, every BLoC, every golden test, every Codemagic build.

You manage the work

You set product priorities and sprint goals. We handle hiring, retention, payroll, benefits, upskilling, and laptops.

Hiring Process

From "we need a Flutter dev"
to onboarded — in 2 weeks.

4-step process pulled straight from how we work. 4 hours to first profile. 2 weeks to a Flutter developer joining your standup.

01
Day 1-2

Requirement Analysis

We begin by understanding your business goals, technical requirements, project scope, and timelines to ensure the right Flutter development approach for your team.

02
Day 3-5

Choose a Resource

Based on your needs, we shortlist and recommend the most suitable Flutter developers with relevant experience and skill sets — 3-5 profiles in 4 hours.

03
Day 6-10

Start an Interview

Interview the selected Flutter developers to assess their technical expertise, communication skills, and project fit before final selection. Live coding, system-design — your call.

04
Day 11-14

Onboarding

Once approved, the developer is onboarded quickly and starts working as part of your team with complete transparency and regular updates. First PR by day 14.

Why Choose WebSenor

10 reasons enterprises pick us
over over marketplaces and agencies.

01

5-step vetting

Resume + technical screen + live Dart + Flutter coding test with Riverpod or BLoC + system-design + culture fit. <4% acceptance rate.

02

100% source code authorization

You get complete ownership of clean, well-documented Flutter source code. Standard MSA assigns IP to you on day 1.

03

Skilled & experienced programmers

Our Flutter developers have shipped one-codebase apps across delivery (offline-first orders), fintech (cards + KYC), B2B field tools (offline sync), and consumer (social + media).

04

Excellent communication

Engineers ensure clear communication, timely updates, and seamless collaboration throughout the project lifecycle. Async-first, written-default culture.

05

Replace any time

Not the right fit? Free replacement in 5 business days. No questions asked. Most teams never need it — but it's there.

06

No middlemen

You talk directly to engineers. No account-manager wall, no chinese-whispers PM filtering communication.

07

Save up to 60%

Senior Flutter developers at India rates — without agency markup, recruiter fee, or freelancer flake. 30-60% cost vs onshore.

08

Time-saving

Time is money. Our Flutter experts deliver projects effectively and efficiently, with 95% talent retention to avoid mid-project churn.

09

Monthly contracts

30-day notice. No multi-year lock-in. Scale your Flutter team up or down as your roadmap shifts.

10

Production experience

They've shipped Flutter apps at 60fps on low-end Android devices, scaled Flutter Web to 100k+ DAU, and rescued failed Flutter projects from other agencies.

Client Voices

What companies say
about hiring from us.

"
★★★★★

We were quoted 8 months for separate iOS + Android teams. WebSenor's Flutter pod shipped both in 14 weeks from one codebase. Game over.

FS
Founder, quick-commerce startup
"
★★★★★

They set up our Melos monorepo properly — internal packages, shared design system, Shorebird code push. We went from a 2-week release cycle to 3 days.

CT
CTO, Series-C fintech
"
★★★★★

Flutter Web from a single codebase actually works at scale. Our WebSenor specialist made it sing — sub-second renders, SEO that converts.

Frequently Asked Questions

Everything you need
to know before hiring.

What does the 14-day SLA actually mean?
From the discovery call (day 1) to the Flutter developer being onboarded and shipping their first TestFlight + Play Internal build (day 14). Typical: shortlist by day 3-5, interviews day 6-10, MSA + repo access day 11-13, first dual-platform build by day 14.
How does the replacement guarantee work?
If a Flutter developer isn't a fit, give us 5 business days notice. We send 2-3 replacement profiles within 4 hours. No replacement fee, no penalty.
Riverpod, BLoC, or Provider — which do your Flutter devs use?
Most new builds we staff use Riverpod 2; BLoC is common in larger teams or apps with rich event-driven domains. We match the developer to your existing pattern instead of forcing ours.
Can Flutter actually replace native iOS + Android?
For most apps, yes. We've shipped 60fps Flutter apps on 2018 Android hardware, deeply integrated platform channels and Pigeon for native SDKs, and used FFI for Rust interop. Where native is required (e.g. complex AR, low-latency audio), we mix Flutter with native modules — and our same team can build both.
What about Flutter Web and desktop?
Yes. We ship Flutter Web (CanvasKit + HTML rendering, with SEO via deferred bootstrap and pre-rendering), macOS, and Windows targets from the same codebase. We're realistic about Web's tradeoffs — it shines for internal tools and admin portals, less so for marketing pages.
Do you handle code push (Shorebird / CodePush)?
Yes. Shorebird in production for OTA Dart updates; we manage the rollout, gating, and rollback workflow inside your CI.
What about IP, NDAs, and source code?
100% source code authorization. Standard MSA assigns all IP — including the Apple Developer + Play Console transfer on request — to you on day 1.
How do you vet Flutter developers?
5 steps: 1) Resume + portfolio screen with shipped apps, 2) Technical screen with our Flutter lead, 3) Live Dart + Flutter coding test (90 min) building a feature with Riverpod or BLoC, 4) System-design round (60 min) on offline-first sync, monorepo packaging, native interop, 5) Culture-fit + reference checks.
