Why outstaff Kotlin talent? Because queueing for full-time hires burns cash and slows releases. Our augmentation model plugs pre-vetted Kotlin specialists with deep fare-collection, NFC, and QR code experience straight into your sprint board. No recruitment fees, no HR overhead, full IP & GDPR compliance. Ramp up or down in days and pay only for the expertise you use. Keep focus on roadmap features while we shoulder payroll, workspace, hardware, and continuous up-skilling.
Result: faster launches, leaner budgets, and a ticketing app your riders love.

What CTOs Say
“Smartbrain.io delivered two Kotlin experts fluent in NFC fare capture and Jetpack Compose within 48 hrs. They integrated seamlessly with our CI/CD pipeline, crushed our backlog, and helped us hit the Tokyo launch five weeks early. Productivity jumped 32 % while my core team stayed focused on roadmap items.”
Michael Carter
CTO
TransitWave Inc.
"Our legacy Java codebase was stalling releases. Smartbrain’s augmented Kotlin engineers refactored modules with coroutines, cutting app start-up time by 28 %. Onboarding took one day thanks to their documented ticketing SDK experience. QA defect rate dropped and stakeholders finally trust our release dates."
Alicia Nguyen
VP Engineering

“PCI compliance kept me up at night. Smartbrain’s Kotlin contractors hardened our QR payment flow with Ktor & encryption libraries, passing audit first try. Deploying extra hands only during compliance sprints saved us 45 % versus hiring full-time.”
Robert Fields
Security Lead
TicketCloud Corp.
“We added three Smartbrain Kotlin devs during peak season. Their prior Shinkansen e-ticket knowledge erased learning curves. Story points delivered per sprint climbed from 52 to 78, and our riders got seat-reservation updates a month early.”
Laura Mitchell
Product Owner
SwiftRail USA
“Budget pressures forced us to reconsider in-house growth. With Smartbrain outstaffing, we onboarded Kotlin specialists only for the commuter-pass module. We saved 38 % in OPEX and met KPI for daily active users without layoffs or overtime.”
Daniel Brooks
CFO
CommuterConnect LLC
“Post-launch, crashes threatened app ratings. Smartbrain provided a 24/7 Kotlin support pod that fixed critical ANR issues in hours. Store rating climbed from 3.4 to 4.6, sustaining our marketing spend ROI.”

Industries We Empower
Urban Transit & Smart Cities
Municipal operators rely on Kotlin-based Public Transport Ticketing Mobile Apps for real-time fare validation, crowd analytics, and seamless IC-card top-ups. Augmented Kotlin teams integrate GPS, Suica, and Pasmo APIs, enabling cities to roll out smart-mobility initiatives without bloating permanent headcount.
Railway & High-Speed Rail
JR-style networks demand snappy seat reservations and Shinkansen e-ticket issuance. Outstaffed Kotlin specialists optimise coroutines for high-concurrency booking engines, ensuring millisecond latency even during Golden Week peaks.
Tourism & Hospitality
Travel apps bundle subway passes with hotel stays. Our Kotlin augmentation adds multilingual UI, dynamic pricing, and QR voucher redemption to delight overseas visitors exploring Japan’s rail grid.
Event Ticketing
Concert and sports venues reuse fare-collection logic for entry control. Kotlin devs customise NFC and BLE scanning modules, speeding gate throughput and cutting paper costs.
Corporate Mobility Programs
Enterprises subsidise commuter passes. Augmented Kotlin squads create admin portals, automate reimbursements, and sync ridership data with HRIS platforms to slash manual claims.
Education & Campus Transport
Universities issue digital IDs doubling as bus passes. Outsourced Kotlin engineers integrate student SSO, enforce ride quotas, and push live shuttle ETAs to reduce wait lines.
Aviation Ground Transport
Airports provide connecting rail tickets. Kotlin experts build SDKs that bundle boarding passes with rail QR codes, enhancing customer journey continuity.
Maritime & Ferry
Island ferries adopt mobile ticketing to replace cash kiosks. Kotlin augmentation delivers offline-first boarding validation and remote update mechanisms resilient to patchy coastal networks.
Ride-Sharing & Micro-Mobility
E-scooter and bike operators integrate public transport passes for MaaS experiences. Outstaffed Kotlin devs stitch together payment gateways, mapping SDKs, and pass-sharing logic.
Public Transport Ticketing Mobile App Success Stories
Tokyo Metro Peak-Load Optimization
Client: Public subway authority
Challenge: App crashes during rush hour threatened the Public Transport Ticketing Mobile App launch.
Solution: Our two augmented Kotlin architects profiled coroutines, replaced legacy I/O with Flow, and introduced on-device caching. Working alongside in-house QA, they delivered a patched build to the store in nine days.
Result: 47 % latency reduction, 0 peak-hour crashes, and a 4.8 store rating within one month.
Nationwide Rail QR Migration
Client: Private railway conglomerate
Challenge: Replace magnetic tickets with a QR-based Public Transport Ticketing Mobile App without disrupting daily ridership.
Solution: A pod of five Smartbrain Kotlin developers delivered modular scanning SDKs, offline validation logic, and phased rollout scripts that co-existed with legacy gates.
Result: 65 % reduction in ticket fraud and 22 % faster boarding times across 520 stations.
Tourist Pass E-Commerce Integration
Client: Major OTA
Challenge: Integrate souvenir rail passes into its Public Transport Ticketing Mobile App storefront within the cherry-blossom season.
Solution: Three augmented Kotlin engineers built React Native bridges, multi-currency payments, and instant voucher issuance, all within the OTA’s PCI-compliant stack.
Result: 38 % upsell rate on transport bundles and 19 % uplift in average booking value.
