WORK WITH SHEERSH TIWARI

Software that fits your process.

I build custom web applications, backend APIs, and integrations for teams whose existing tools do not fit the way they work. The focus is a useful interface backed by dependable data flow.

Web applications & dashboardsBackend APIs & integrationsReact / Java / Python

Connect the tools you already use

An integration has to handle more than a successful request. Authentication, changes in source data, retries, and conflicting updates all affect whether people can rely on it.

Internal dashboards and task interfaces.
REST or GraphQL API development and integration.
Data synchronization between a web application, database, and third-party service.

Choose the stack around the constraints

My work spans React, Next.js, TypeScript, Java Spring Boot, Python, PostgreSQL, and MySQL. Existing infrastructure, maintainability, and the people taking over the system guide the choice.

The portfolio includes a Google Sheets and PostgreSQL synchronization gateway, booking and financial integrations, and the कामCREW control interface. These are examples of the kinds of boundaries I work across, rather than a promise that every integration is interchangeable.

A scoped build, with a clear handover

We agree on what is included and who will maintain it. Ongoing support can be discussed as part of that scope.

Clarify the users, inputs, outputs, and systems involved.
Define the API contract and smallest useful interface.
Build and review a working version against agreed scenarios.
Document configuration, operation, and remaining limitations.

An example of a connected interface

कामCREW connects a Next.js interface to the Hermes gateway and SQLite-backed task state, using server-sent events for live updates. The case study explains the boundaries between my control layer and the underlying runtime.

BEFORE WE START

Common questions.

Can you work with an existing application?

Yes. Start by sharing the stack, the change needed, and how the current system is operated. We can then assess the affected interfaces and define a limited first scope.

Do you build both the interface and backend?

Yes. My work covers React and Next.js interfaces, Java or Python backends, APIs, and relational databases. The specific stack follows the project requirements.

Can you guarantee a delivery date before reviewing the system?

A useful estimate needs the requirements, dependencies, and access constraints. We agree on scope and acceptance criteria before making a delivery commitment.

A USEFUL FIRST STEP

Tell me what needs
to work better.

Share the task, the systems involved, and the outcome you need. We can start with a focused conversation.
