Stop Losing Sprints to JavaScript Developers Who Can't Own the Stack

Most companies don't have a JavaScript problem they have a "developer who knows one framework but breaks everything else" problem. Here's why it compounds, and how we fix it.

Senior JavaScript engineers who can own Node, React, and TypeScript end-to-end take 3–6 months to hire locally and cost $180k–$240k loaded

Framework specialists ship fast on one layer and create integration debt on every other

Offshore JavaScript developers who look good in interviews disappear mid-project or need constant unblocking

AI tools write JavaScript fast and produce async bugs, security holes, and untested edge cases that a junior won't catch

Pre-vetted JavaScript engineers with 5–10+ years on real production systems - full-stack ownership, not framework tourists

AI-driven development workflows that compress build timelines without producing unmaintainable async spaghetti

Dedicated engineers with a product-first mindset - they understand the business logic, not just the syntax

Human-reviewed, production-ready output. AI increases throughput, seniors ensure correctness, security, and test coverage

Frequently Asked Questions

India has one of the deepest pools of senior JavaScript engineers in 2026. Devlyn adds AI-driven development workflows on top — so you get senior full-stack engineers who ship 3× faster than traditional offshore JS teams. English-first communication, timezone overlap, and transparent rate cards mean no offshore friction.

Three things. Senior-only talent every JavaScript developer has 5–10+ years of production work across Node, React, and TypeScript, not a bootcamp certificate. AI-augmented workflows Claude and Cursor are standard tools, not optional extras, and every AI-generated PR has a stricter review process than human code. And full-stack ownership our engineers own the API contract, the frontend integration, and the deployment pipeline, not just one layer.

2 vetted profiles in your inbox within 24 hours. Intro call same week. MSA, NDA, and access provisioning in 24 hours. First commit within 7 days of your initial inquiry.

Our engineers use Claude and Cursor for code generation, refactoring, and test writing. Every AI-generated PR goes through two reviewers and requires test coverage delta. AI speeds up the build the senior engineer makes sure async logic is correct, error handling is complete, and nothing ships to production untested.

PR review SLA under 4 hours. TypeScript enforced by default. Every engagement starts with a codebase audit existing patterns, naming conventions, test coverage. We document architecture decisions as ADRs, enforce ESLint and Prettier from day one, and run integration tests on every deployment. No cowboy code.

Engineers default to a 4-hour overlap with your team's working hours. We support IST, GMT, CET, and EST overlap. Daily async Slack standups. Weekly demo and code review calls. PR reviews and Linear ticket updates happen inside your working hours - no morning surprises when you open GitHub.

Standard MSA assigns all IP to you. Mutual NDA signed before any access provisioning. We can operate fully within your cloud accounts and GitHub org so source code never leaves your perimeter. SOC 2-aligned controls available on request.

During the 7-day trial: tell us, and we replace within 48 hours. No fee, no awkward conversation. After the trial: still replaceable, just on normal pace. The price reflects India loaded cost not skill. We'd rather replace fast than have you stuck with the wrong engineer.
