We engineer 
ambitious software, intelligent agents, and scalable digital products.
fynk is a product engineering studio led by Vansh. We work with founders who need a product in production and with design studios who need engineers they can put in front of a client. Fixed scope, fixed price, shipped to the edge.

What we build.
Product engineering
Web and mobile products built to ship and keep shipping. Next.js, React Native, typed APIs, auth, billing, the boring parts done properly.
- SaaS dashboards
- Consumer apps
- Marketing sites that load fast
- Design-system implementation
AI agents
LLM systems that do a job: answer customers, run workflows, read documents, call tools. Evaluated, logged, with a human handoff when confidence drops.
- Support and voice agents
- Retrieval over your data
- Tool-calling workflows
- Eval harnesses
Infrastructure
The plumbing under the product. Queues, schedulers, scrapers, webhooks, deploys and the monitoring that tells you when something breaks.
- Background job systems
- Data pipelines
- Third-party integrations
- CI/CD and observability
For design studios.
You sell the whole product. We build the part your team doesn't: the app, the backend, the deploy. Your client never has to know we exist.
- Fully white-label. Your brand on the repo, the deploys and the invoice.
- No credit taken. No portfolio use, no footer links, no outreach to your client.
- Figma to production at 1:1. Tokens, variants and responsive behaviour as designed.
- Fast by default. Edge rendering and performance budgets agreed up front.
- Backends included. Payments, CRMs, auth providers and legacy APIs wired in.
Three ways to work together.
Each starts from a known floor and is fixed after one scoping call, so there are no surprises later. We build on a preview URL you can open from day one and ship nothing without a passing pipeline.
