Key Outcomes

Led a three-person team from a problem in the field to a working product for NGOs, volunteers and CSR teams.
Designed three experiences on one shared system, each around why that group opens it.
Moved from a web app to a native app after research showed many volunteers weren't comfortable opening a web app.
Directed the build with AI: decided what to build, what to cut and how it should work, while AI wrote the code.

Platforms

One place for NGOs, volunteers and CSR teams to run volunteering, replacing WhatsApp groups and spreadsheets with structured events, shifts, tasks and verified hours.

Screens

An event page: what it's for, who's hosting, and the shifts volunteers can sign up for.
Volunteers update their own tasks during an event: to do, in progress, blocked or done.
Clocking out asks how it went, so logged hours reach the NGO with a status to approve.
The NGO side: total hours, active volunteers, events run and the share of hours verified.
The NGO side: total hours, active volunteers, events run and the share of hours verified.

Sevarah is a volunteer platform connecting NGOs, volunteers and corporate CSR teams. It's a small team effort: I lead the product, working with a UX/UI designer and a researcher and art director. The platform is built with AI: I decide what gets built and why, and AI writes the code.

Concept

The Problem

Volunteer coordination in India runs on WhatsApp groups and spreadsheets. Volunteers can't easily find opportunities, NGOs struggle to track who showed up, and CSR teams have budgets but no simple way to deploy them or measure the impact. Three groups, three different workflows, and nothing connecting them.

Solution

Three Experiences, One System

Each group gets an experience built around its own job, all running on one shared system underneath.

01

NGOs

Create events and shifts, manage volunteers, track attendance and approve the hours volunteers log.

02

Volunteers

Find opportunities by cause, place and time, clock in and out, update tasks and build a verified record of their hours.

03

CSR Teams

Find vetted NGOs, sponsor events, track employee participation and pull reports ready for CSR compliance.

Research

Built for the People Using It

Talking to NGOs and volunteers changed the plan. Many of the volunteers the team spoke to weren't comfortable with technology, and asking them to open a web app in a browser was already a barrier. So we built a native app, where Sevarah sits on the home screen like any other app they already use.

01

App over browser

A native app removed the step that lost people: finding and opening a web link.

02

Plain choices

Key moments use simple, guided options. Clocking out asks how it went (done, still working, partly done or couldn't finish) instead of showing a form.

03

Hours you can trust

Every logged hour reaches the NGO with a status to approve, so impact reports are verified, not self-reported.

AI Process

Directing the Build with AI

I don't write code. My role is to be the brain of the build: research the options with AI, decide what to build and what to leave out, and set the rules the code has to follow. AI writes the code inside those rules.

01

Research before decisions

Every major choice, from sign-in to how data is shared between the three groups, was researched with AI before committing to it.

02

A design system, not one-off screens

Colours, type and components are defined once as tokens and reused everywhere, so nothing is hard-coded screen by screen.

03

Each group sees only its own data

I set the rule that every organisation's data stays separate, and that each group only sees what its role needs.

04

Stack chosen with AI

After comparing options with AI, we went with Next.js for the web app, Supabase for the database and Clerk for sign-in.

Team

Team & My Role

Sevarah is a team effort, and each of us owns a part of it.

01

Product Lead (me)

Product vision, priorities and the key decisions, plus directing the AI build.

02

UX/UI Designer

Interaction design, user flows and interface design across all three experiences.

03

Researcher & Art Director

User research with NGOs and volunteers, brand identity and visual direction.

Next

Using What a Phone Can Do

Moving to a native app opened up features a web app couldn't offer. The team explored using Bluetooth and proximity to confirm a volunteer is actually at an event, so attendance can be verified nearby without codes or paperwork.
