Hire Dedicated Developers in India
Hiring on Upwork or Toptal means sifting through hundreds of unvetted profiles, interviewing strangers cold, and hoping the person who wins the proposal can actually ship production code. Vellumarc is not a marketplace — we are a real agency that vets engineers, assigns a tech lead to every engagement, and puts our name on the output. You get one of four developer shapes: full-stack and Next.js engineers, mobile engineers, AI/ML engineers, or specialists and designers. Three engagement models: hourly ($25–$80/hr), monthly retainer ($2.5k–$8k/dev/month, tech-lead supervision included at no extra cost), or project-based fixed scope. You interview every candidate before we place them — paid 4-hour trial slot available. Replacement guarantee within 14 days, NDAs and IP assignment signed by default. India team with US, UK, and AU time-zone overlap. Start with a free audit call and we will have a shortlist on your desk inside five business days.
Who you can hire
Four developer shapes — pick a single contributor or a small pod with a tech lead.
Full-Stack & Next.js Engineers
Senior engineers fluent in React, TypeScript, and the Next.js App Router — Server Components, server actions, tRPC, Prisma, and Postgres. They have shipped SaaS products, internal tools, and e-commerce platforms to production, not just to a staging URL. Comfortable owning a feature end-to-end: data model, API, UI, and deployment on Vercel or AWS.
Mobile Engineers
React Native and Flutter engineers with live App Store and Play Store titles in their portfolio, plus native specialists in Swift and Kotlin for performance-critical work. They handle push notifications, deep-linking, offline sync, in-app purchases, and App Store review submission — every step from architecture through to the approval email.
AI / ML Engineers
Engineers who build production LLM applications — RAG systems with vector DBs, prompt-engineering pipelines, fine-tuning runs, eval harnesses, and latency-optimised inference endpoints. Not researchers writing papers: practitioners who know when to call the OpenAI API, when to fine-tune, and when the answer is a well-structured regex.
Specialists & Designers
Shopify developers, UI/UX designers, DevOps and platform engineers, product managers, and QA engineers — the exact role your current team is missing. Hire one specialist for a six-week sprint or embed them into your team long-term. Same vetting bar, same tech-lead oversight, same replacement guarantee as every other engagement.

How hiring works
Five-stage process — brief to onboarded developer in under two weeks.
Brief
You tell us the role — stack, seniority level, hours per week, time-zone requirements, and project context. A one-page brief or a 20-minute call both work. We ask the questions that save time later: team size, codebase maturity, communication style, and how hands-on you want the tech lead to be.
Vetting
We run an internal shortlist against the brief and surface two or three candidates — each with a portfolio, relevant code samples, and a short written summary of why they fit your specific context. No padded profiles, no bait-and-switch. The person in the shortlist is the person who shows up.
Interview
You interview each candidate directly — technical screen, culture fit, whatever your process requires. If you want more signal before committing, we offer a paid 4-hour trial slot: a real task from your backlog, reviewed by our tech lead. You only proceed if you are confident.
Onboard
Contract signed, NDA executed, IP assignment in place — all in a standard engagement doc, no surprises. Tooling access granted, repo permissions set, first sprint planned. Most developers ship their first meaningful commit by the end of week one. Tech-lead check-in is scheduled from day one.
Manage / Replace
Weekly check-ins with you and the developer. Velocity tracked, blockers escalated early. If a developer is not the right fit for any reason — technical, communication, or otherwise — our replacement guarantee kicks in within 14 days: a new shortlist at our cost, pro-rata refund on the gap period.
