Proven Results

FinTech Checkout Optimisation

A venture-backed payments startup needed to Hire Junior TypeScript developer talent fast after a surge in transaction volume threatened roadmap deadlines. Our two-member junior squad joined within 72 h, pairing daily with senior engineers while refactoring TypeScript services for PCI compliance. The team automated unit tests and tightened typing, slashing deployment errors by 64 % and freeing seniors for strategic feature work.

E-Commerce Page-Load Boost

An omni-channel retailer faced cart-abandonment due to sluggish React-TypeScript pages. Two of our juniors rewrote legacy JS components into strict TypeScript, introduced code-splitting, and optimised API calls. After eight weeks the store’s first-contentful-paint improved by 42 %, raising mobile conversion by 11 % and justifying a full expansion of the augmented pod.

Health-Tech Data Dashboard

A tele-medicine provider lacked bandwidth to deliver a clinician dashboard before regulatory cut-off. Three juniors integrated via GraphQL, implementing strongly-typed hooks and Storybook components. Working in tandem with QA, they delivered the MVP in six sprints, enabling on-time certification and reducing reported UI bugs by 58 %.

Outstaff Junior TypeScript Talent

Industries We Empower

FinTech Platforms

Junior TypeScript developers reinforce outstaffing teams building KYC dashboards, event-driven payment gateways, and regulatory reporting micro-services, delivering strict typing that prevents costly transaction errors.

E-Commerce & Retail

Outstaffed juniors convert legacy JS storefronts to React-TypeScript, implement lazy-loading, and optimise Lighthouse scores—boosting conversions while seniors focus on core merchandising logic.

Health-Tech SaaS

HIPAA-compliant portals rely on TypeScript for safer data handling. Our juniors craft typed APIs, analytics widgets, and accessibility-ready UI components under senior review.

Ed-Tech Solutions

From adaptive learning engines to real-time quizzes, augmented TypeScript talent adds gamified components, maintains WebSocket messaging, and ensures cross-device stability.

Logistics Tech

Junior TypeScript coders integrate map SDKs, write route-optimisation services, and automate warehouse scanners—lowering shipping costs via precise, typed code.

Media Streaming

Outstaffing lets broadcasters embed juniors to build TypeScript-based player controls, subtitle renderers, and server-side rendering for SEO-rich landing pages.

Prop-Tech Apps

Typed GraphQL schemas, interactive 3-D tours, and CRM automations are common tasks our juniors undertake for real-estate innovators using React/Next.js.

MarTech & AdTech

Augmented juniors wire event trackers, extend analytics dashboards, and maintain high-throughput bidding services using Node + TypeScript in cloud environments.

Frequently Asked Questions

What is the true cost to hire TypeScript developers via smartbrain.io compared to in-house?

When you Hire Junior TypeScript developer talent through smartbrain.io you pay a transparent monthly service fee that already includes recruitment, payroll, equipment, and local compliance. In-house hiring, by contrast, hides 30-50 % extra costs in benefits, taxes, real-estate, and ongoing HR administration. Add the average 45-day vacancy period and you are paying for lost velocity, too. Our clients typically save 18–35 % total cost of ownership while gaining the flexibility to scale headcount up or down every sprint. Because we operate in multiple talent hubs, you also benefit from favorable regional salary benchmarks without compromising quality or overlapping time zones.

How does smartbrain.io protect my intellectual property when I outstaff TypeScript talent?

All junior TypeScript developers sign strict NDAs, invention-assignment, and confidentiality agreements before touching your code. Our contracts bind both the developer and smartbrain.io, giving you dual protection. Secure VPNs, SSO-locked repositories, and role-based permissions ensure source code never leaves controlled environments. We also offer optional dedicated GitHub organisations audited weekly. Finally, our local legal entity in each developer’s country allows us to enforce IP clauses under jurisdiction favorable to you, removing enforcement uncertainty that often worries CTOs.

Can I align outstaffed juniors with my team’s time zone and agile rituals?

Yes. We prescreen for overlapping hours and communication style. 80 % of our junior TypeScript pool works US business hours or within ±3 h. Daily stand-ups, sprint reviews, and retrospective attendance are written into the Statement of Work, ensuring seamless participation. If schedule drift occurs, our Customer Success team intervenes within one business day.

What if a developer is not the right culture or skill fit?

Our replacement guarantee lets you request a new Junior TypeScript developer at no extra cost within the first 14 days. Because we maintain a live bench of vetted candidates, swaps happen in as little as 48 h, minimising disruption.

How long from first contact until a developer starts contributing code?

Most clients complete onboarding in five business days: 30-min discovery call, 48-hour shortlist, one round of client interviews, then contract sign-off and laptop ship. Developers commonly push their first PR within week one.

What contract terms and notice periods do you offer?

Engagements are month-to-month with a simple 15-day notice period. Need more flexibility? Scale down to part-time or pause the service over holiday freezes—no penalties.

Why not hire in-house instead of using smartbrain.io’s TypeScript staff-augmentation?

In-house hiring locks you into fixed salaries, benefits, and long procurement cycles. With outstaffing you gain on-demand capacity, zero HR overhead, built-in vetting, and the ability to try before you buy. Many clients later convert top juniors to FTE using our buy-out option once product-market fit is proven.
