eCommerce & Retail

Online retailers tap outstaffed ReasonML talent for type-safe cart logic, recommendation engines, and A/B testing dashboards. This reduces checkout bugs, boosts conversion rates, and frees internal staff to craft growth experiments.

IoT & Industrial

Manufacturers enhance device portals, edge-analytics UIs, and monitoring consoles by hiring remote ReasonML experts. Functional paradigms cut race conditions, while outstaffing ensures flexible scaling during pilot phases.

AdTech & MarTech

Advertising platforms depend on millisecond decisions. ReasonML developers optimize data pipelines and real-time bidding dashboards. Staff augmentation keeps burn-rate predictable during traffic peaks.

Ed-Tech

Educational software providers offload LMS component builds to outstaffed ReasonML teams, ensuring interactive widgets stay bug-free across browsers and semesters without ballooning payroll.

Logistics & Supply Chain

Logistics enterprises employ ReasonML coders for route-optimization UIs, track-and-trace maps, and contract management. Outstaffing grants round-the-clock development against tight SLAs.

Media Streaming

OTT services integrate ReasonML to manage state-heavy player controls and recommendation overlays. External engineers mitigate churn without distracting core video engineers.

GovTech & Public

Public-sector agencies need strict reliability. Outstaffed ReasonML specialists upgrade legacy portals, offering safer code and faster citizen services under capped budgets.

Client: VC-backed online brokerage.
Challenge: They had to Hire ReasonML developer talent quickly to eliminate JavaScript-driven data race conditions jeopardising trade execution.

Skill Groups

Front-End Architecture

Component-Driven UIs: Augmented ReasonML developers craft highly composable, strongly-typed React/ReasonReact components that eliminate className collisions and state leaks.
Business Value: Faster feature releases and a tangible reduction in regression QA cycles free your core engineers for roadmap innovation, not firefighting.

Typed Back-End APIs

Type-Safe Services: From Node/Express bridges to GraphQL resolvers, ReasonML programmers ensure end-to-end type safety, shrinking integration bugs.
Benefit: Lower maintenance cost and happier API consumers—internal or external—because contracts can’t drift.

Cross-Platform Mobile

ReScript + React Native: Outstaffed engineers deliver a single type-safe codebase targeting iOS and Android.
Benefit: Ship features to both stores simultaneously and slash duplicate effort without sacrificing runtime performance.

Legacy JS Migration

Incremental Refactors: Specialists wrap existing JavaScript with ReasonML bindings, letting teams migrate module-by-module, avoiding big-bang risks.
Benefit: Continuity of service plus measurable decline in production incidents.

Tooling & DevOps

CI/CD Automation: Dev augmentation covers ReasonML-specific linting, formatting, and test pipelines, integrating with Docker and Kubernetes.
Benefit: Repeatable builds, quicker rollbacks, and dev-prod parity that shortens MTTR.

Performance Optimisation

Profiling & Tuning: Senior ReasonML coders analyse bundle size, harness immutable data, and implement memoisation.

FAQ

What is the real cost to hire ReasonML developers through smartbrain.io compared to in-house recruitment?

The total cost to Hire ReasonML developer talent via smartbrain.io is typically 30–45 % cheaper than recruiting in-house once you factor in sourcing ads, agency retainers, HR salaries, onboarding time, payroll taxes, benefits, and bench risk. Our transparent hourly or monthly rates already include those overheads, letting you treat talent as a predictable OPEX line. There are no placement fees, and you pay only for productive hours. Because we can place pre-vetted ReasonML engineers in as little as 48 hours, you also save two to three months of unfilled vacancy cost—lost sprint velocity, late features, and opportunity cost. All invoices are issued from a US-compliant entity, streamlining your procurement workflow.

How does smartbrain.io protect my IP when I outstaff ReasonML developers?

Every augmented engineer signs a strict NDA and IP assignment agreement before onboarding. Code is committed to your repositories, and all work is performed within your secure tooling. smartbrain.io maintains ISO-27001-aligned procedures, encrypted communication channels, and enforces least-privilege access. You retain full ownership of all deliverables created by the ReasonML programmers, eliminating IP ambiguity that can arise with freelancers or outsourcing firms.

Will time-zone differences slow down collaboration with remote ReasonML coders?

No. We specialise in sourcing ReasonML developers who can guarantee at least 4 hours of overlap with US business time. Daily stand-ups, code reviews, and pair-programming sessions are scheduled to suit your team. Our talent spread across North and South America and Europe ensures latency-free communication without sacrificing price advantage.

What contract terms are available for ReasonML staff augmentation?

Contracts start at a one-month minimum, extendable in weekly increments. Need a long-term dedicated squad? We support multi-year MSAs. Need only a short burst of capacity? Scale down with 10-day notice. Flexible terms mean you never over-pay for idle resources, a major perk over traditional hiring.

How do you vet a Hire ReasonML developer before presenting them?

Each candidate passes a 4-stage assessment: (1) portfolio screen, (2) live coding in ReasonML/ReScript, (3) architectural interview with a senior functional architect, and (4) soft-skills evaluation simulating real sprint ceremonies. Fewer than 3 % reach our client roster, ensuring you meet only elite ReasonML engineers.

What happens if the placed ReasonML engineer is not a fit?

smartbrain.io offers a two-week risk-free replacement guarantee. If performance or culture fit is off, we’ll provide a replacement engineer within days at no extra cost, ensuring project continuity.

How fast can I start after I decide to hire ReasonML developer resources?

After our 15-minute discovery call, you receive curated CVs within 24 hours. Typical clients conduct one technical interview and sign the SoW the next day. Average time-to-first-commit is under 72 hours, meaning you add productive capacity before your next sprint planning.
