Hire a full stack developer who owns the whole path to production

Soham Dang is a Senior Full Stack Developer available for product work: one engineer who takes a feature from data model through API, interface, authentication and deployment, rather than three who each own a slice of it.

The expensive part of splitting a product across specialists is not the salaries. It is the seams — the week lost because the API returns what the backend found natural rather than what the interface needs, or the auth rule that exists in the UI but not the endpoint behind it.

Hiring one person who works across the whole stack removes those seams. The contract between frontend and backend gets decided once, by someone who has to live on both sides of it.

What gets built

  • Data models designed around real queries

    MongoDB schemas shaped by the reads the product will actually serve, with compound indexes driven by explain plans rather than guesses.

  • REST APIs designed as contracts first

    Node.js and Express endpoints with request validation, structured errors and versioned shapes, agreed before either side is written.

  • Interfaces that survive a year of changes

    React and Next.js with TypeScript, rendering strategy chosen per route, and a component layer that new features extend instead of fork.

  • Authentication and access control

    JWT and OAuth sign-in with role-based access enforced in middleware, so a missed check in one handler cannot leak data.

  • Dashboards that stay fast as data grows

    MongoDB aggregation pipelines doing the rollups, rather than fetching everything and summing it in JavaScript.

  • Deployment and the boring parts after

    CI/CD to Vercel or Render, environment configuration, production monitoring and the performance work that follows launch.

Evidence this works

Avani Business OS is the clearest case. It is a 25+ module multi-tenant platform covering tasks, projects, meetings, leads, expenses, assets, billing, KPIs, finance, email CRM and a full HR suite, which replaced more than ten separate internal tools and is used daily by 10,000+ people.

The HR side of it digitised onboarding, leaves, payroll and salary slips, removing more than 20 hours of manual work a week. Payroll generates salary slips directly from attendance and leave data rather than from a spreadsheet someone maintains.

How the work runs

  1. Scoping

    Requirements become data models and API contracts. Ambiguity gets found here, where it costs a conversation instead of a rewrite.

  2. Foundation

    Schema, auth, access control and deployment pipeline first. Everything after is cheaper once these are settled.

  3. Vertical slices

    Features ship end to end — database through interface — so there is always something real to react to.

  4. Hardening

    Query performance, error paths, regression testing and monitoring, before the feature list gets any longer.

Common questions

When should a business hire a full stack developer?

A full stack developer fits when the product is small enough for one engineer to hold in their head end to end, when speed matters more than specialisation, or when the frontend and backend need to be designed together. Large products with many parallel teams usually need specialists instead.

What technologies does Soham Dang use for full stack work?

React.js, Next.js and TypeScript on the frontend; Node.js and Express.js for REST APIs; MongoDB with Mongoose for data; JWT and OAuth for authentication; and CI/CD to Vercel or Render for deployment.

Can Soham Dang work on an existing codebase?

Yes. Much of his work at Avani Enterprises and MS Infracon involved extending and restructuring live production systems, including moving asset delivery to Cloudinary and cutting page load time by 40%.

Is Soham Dang available for remote full stack work?

Yes. He is based in Rohtak, Haryana, India and works remotely with teams worldwide as well as with companies in Delhi NCR and Gurugram.
