Kolkata IST
Android for Mumbai brands
Kotlin Android for Mumbai brands, built to hold an install spike, and to keep the users that spike buys you past the first week, which is the harder half.

01The practice
Native, hybrid or a web app. What the app has to do on the device decides which of these is right.
Where an app is won or lost · Day 30
02Services
| Native apps Kotlin and Jetpack Compose against the current SDK. Worth it when the app has to stay smooth on a crowded network and a two-year-old handset. | Hybrid and cross-platform apps One React Native or Flutter codebase for both stores. The usual answer when a campaign has to launch on iOS and Android on the same date. | Web apps and PWAs An installable web app when a Play listing is not worth the overhead. It updates without a release, which matters when the offer changes weekly. | |

03Included
Most installs are lost before anyone sees the product. We instrument that path and treat drop-off there as a defect, not a marketing problem.
Day one, day seven and day thirty tracked from the first release, so the roadmap argues from data rather than opinion.
Tunnels and crowded cells are normal here. The app queues work offline and syncs when the signal returns rather than showing a spinner.
A slow first open is the most common reason an install does not survive week one. It is set as a number and watched.
Backend and onboarding load-tested at the install volume your media plan predicts, before the campaign runs.
Source, keystore and Play Console ownership in your name. Nothing depends on us staying.
04Working from Mumbai
We are a Kolkata studio. Here is what that actually means for a Mumbai client, stated plainly.
Where your copy or product needs legal or compliance sign-off, we plan that review as a scheduled stage rather than discovering it a week before launch.
Sale-day traffic, warehouse feeds and returns are where most Mumbai commerce builds actually strain. We load-test for the spike, not the average.
Launch dates here are set by a campaign, not by a sprint board. We work to the date that has already been bought.
IST throughout, so a 10am standup in Mumbai is a 10am standup for us. No overnight handoff and no waiting a day for an answer.
Every invoice carries our West Bengal GSTIN. IGST applies across state lines, and the input credit is claimable. No offshore paperwork.
Everything runs on video, in your tracker, with a staging URL you can open whenever you like. Nothing about the work depends on being in the same room.

05Process
Five stages, a scope fixed in writing, and a senior Android engineer in your standup rather than behind an account manager.
We agree what the first release does not do. Who opens the app, on what handset, and the one job it has to finish. When a media date is already bought, cutting scope is the only lever that works.
Screens drawn to Material, not a desktop mock shrunk down. Clickable flows at real Android densities, with thumb reach, the back gesture and notification behaviour decided before anyone writes code.
A signed build on your phone every fortnight. Two-week sprints, each ending with an internal-track release you can install and use. Code lands in your repository as it is written.
Real handsets, and the backend at spike volume. A device lab pass, a battery and cold-start run, and a load test of the backend at the install volume your media plan predicts.
Staged rollout, then whatever the crash log says. We ship to a small percentage first and watch. After launch, monthly reviews on crashes, retention and the screens people abandon.

06Results
A sample of the products and apps we have shipped. The portfolio has the rest, with the numbers attached.
Sales
Bean-to-bar chocolate and nut-butter machinery sold to craft producers in over a hundred countries. A deep, technical catalogue that buyers could not navigate, restructured around how a chocolate maker actually shops for equipment.
+39% Organic traffic
Organic traffic
Ginger kombucha and fermented banana beer made to Ugandan home recipes. A site built to carry a heritage product into modern retail conversations, online and off.
Conversion rate
Crystals, incense and sound-therapy pieces sold across the UAE and the wider Gulf. A poorly built store replaced with premium storytelling visuals and a checkout path that stops asking the customer to work.
+30% Organic traffic
Organic traffic
Farm-to-market kratom and kava from a family-owned Southeast Asian farm, sold to a US audience that reads labels closely. Six years of SEO equity, hundreds of products and thousands of pages moved off WooCommerce with every ranking intact.
+45% Conversion
Page load
Microsoft-ecosystem consulting out of Santa Clara and Pune: AI copilots, Fabric data platforms, legacy modernisation. A rebrand carried through into a site that makes a complex service offering legible in one pass.
Direct revenue
Stress balls, journals and planners for people managing their own mental load. An established Amazon seller that wanted a direct channel of its own: catalogue ported across, multi-market listings configured, conversion designed for.
No.1 Channel, ahead of Amazon

Still unsure?
Ask us anything before committing to a call. Most questions get a real answer within a few hours.
hello@syscodes.inYes. We are a Kolkata studio working on IST, with the same hours as your team. Weekly video calls, your tracker, and a staging URL you can open whenever you like.
That is what we test for. Backend and onboarding are load-tested at the volume your media plan predicts, before the campaign runs rather than during it.
By instrumenting the first ninety seconds and the day-thirty cohort from launch, then fixing what the numbers show. Retention work without measurement is guesswork.
Yes. Tunnels and congested cells are normal here, so the app queues work offline and syncs on reconnect rather than blocking on a spinner.
If the app leans on sensors, background sync or heavy offline storage, Kotlin. If Android and iOS need the same product on one budget, React Native usually wins.
Yes, including listing copy, screenshots, the data-safety declaration and staged rollout. The Play Console account stays in your name.
An MVP is about eight weeks, a full product twelve to sixteen. If you have a media date, we scope backwards from it.
