Custom software development studio
Web platforms, desktop applications and mobile apps — engineered end to end, AI-assisted, secured by default, and built to be found. No templates, no hand-offs, no guesswork.
01 — Services
Most problems do not respect platform boundaries. We work across all of them so the architecture stays coherent from database to device — and so what you launch can actually be found.
Business platforms, dashboards, portals and APIs. Built to handle real data, real users and real load — not just a pretty demo.
Native-feeling desktop tools for work that never leaves the office — file-heavy, hardware-connected or simply faster offline.
Android and iOS apps that work where your users actually are — including the places with one bar of signal.
Software nobody finds is software nobody uses. We fix the technical foundations that decide whether you rank — then measure what actually happens.
02 — Work
Every one of these is a working, clickable demo — not a screenshot. Each is built the way its own industry actually works, so a diamond ledger does not look like a payroll run.
AI-assisted engineering
We are not going to tell you AI solves your business. We will tell you exactly where it pays for itself — and where a plain database query is the better answer.
AI-assisted scaffolding, code review and test generation across our own delivery pipeline — broader coverage and fewer regressions inside the same timeline.
Document and invoice extraction, natural-language search over your own data, smart categorisation and assistants that answer from your records — not the open internet.
Anomaly detection on spend and stock, demand and cash-flow forecasting, automated reconciliation, and alerts that fire before a problem becomes a cost.
We are explicit about what a model sees. Sensitive records can stay on your own infrastructure, and we tell you plainly when a feature would send data to a third party.
Security
Payroll records, customer data and financial ledgers are the things we are most often asked to hold. That shapes how we set servers up on day one — not after an incident.
HTTPS everywhere with auto-renewing certificates, default-deny firewalls, and admin surfaces kept off the public internet entirely.
A separate database user per application, scoped to its own schema. One compromised site cannot read another’s tables.
Permissions defined in data, not hardcoded — so roles can change as the organisation does, with every change recorded.
Who approved the payroll run, who edited the rate, who exported the data. Answerable months later, because it was logged at the time.
Daily, stored away from the server they came from — and restore-tested, because an untested backup is a hope, not a plan.
Data minimisation, defined retention and a guaranteed export path, so your obligations under India’s data protection regime stay satisfiable.
03 — Approach
Small team, direct line, no account managers in between. You talk to the people writing the code.
We map the real process first — who does what, where it breaks, what it costs. Software comes after the problem is clear.
Data model, integrations and platform choices decided up front, so month six does not become a rewrite.
Short cycles with working software you can open, click and argue with. Feedback changes the next cycle, not the invoice.
Deployment, migration, training and documentation — then we stay on for the months where it matters most.
04 — Stack
We pick well-supported, long-lived technology on purpose — because someone has to maintain it long after launch.
05 — Why Plexowave
Large firms give you process and a queue. Solo freelancers give you speed and a single point of failure. We aim squarely at the gap.
Source code, database and documentation are part of the deliverable conversation from day one — never a hostage negotiation later.
We design for the basement, the site office and the two-bar connection — because that is where the work really happens.
If something will not fit the timeline or the budget, you hear it before the contract — not in week four.
Migration, training, monitoring and the unglamorous month-two fixes. Shipping is the middle of the job, not the end.
Choosing
Three ways to get software built. We are one of them, and the wrong one for a good number of projects - so here is the reasoning rather than the pitch.
| Aspect | Freelancer | Studio | Large agency |
|---|---|---|---|
| Best fit | Short, well-defined, self-contained work - a theme, a landing page, a script | Work where understanding the domain is most of the job, and the people who design it build it | Large multi-year programmes needing many people on the ground at once |
| Who you actually talk to | The person doing the work | The person doing the work | An account manager, usually not the engineers |
| Cost | Lowest, and the right answer more often than studios admit | Higher than a freelancer, well below agency rates | Highest, and much of it is process and management overhead |
| If the work grows | Becomes the constraint quickly | Scales to a point, then honestly stops | Scales furthest - this is the real reason to choose one |
| If someone leaves | The project stops | Continuity, provided the code and docs are handed over properly | Absorbed without you noticing |
| Process weight | Almost none, which cuts both ways | Enough to be accountable, not enough to bill for | Formal, documented, and priced into every change |
| Contractual 24/7 support | No | Ask directly, and accept a straight answer - small teams often cannot meet this honestly | Yes, with named response times |
If your project is a short self-contained task, a competent freelancer will do it faster and cheaper and you should not pay studio overhead for it. If you need a hundred people for two years, you need an integrator.
Questions
It depends on the number of user roles, the integrations and how much data has to be migrated - not on the number of screens, which is what briefs usually enumerate. We give a real estimate after discovery, with the assumptions written down and the parts we are unsure about named as unsure.
A focused internal platform is typically eight to fourteen weeks from first conversation to production. Larger multi-module systems run longer and are delivered in stages, with the first module live while the next is being built. If nothing reaches production before month nine, ask why.
Yes, entirely, including the repository and the deployment configuration. There is no runtime licence and nothing that stops another developer taking it on. Your cloud and app-store accounts stay in your name.
Usually. Most builds start by integrating with something already in place - an accounting package, an ERP, a legacy database. Replacing everything at once is rarely the right call, and a phased path is safer.
A support period is included, after which most clients take a retainer for changes and monitoring. Neither is a lock-in: the code is yours and documented well enough for someone else to pick up.
Yes. The work is remote, and a few hours of overlap matters more than geography. Discovery, hardware work and field pilots are the phases where being on site counts, and those are planned for specifically.
No, and it is the normal starting point. Describe the problem rather than the solution. If the answer turns out to be a product you can buy, or a better process rather than software, we will say so.

A short description of the problem is enough to start. We will tell you honestly whether we are the right people for it.
