You think.
We build.
The moment in between is T−0.

In a launch countdown, T−0 is the instant preparation becomes liftoff. That's where we work — turning your ideas into web platforms, mobile apps, SaaS products, AI automation and hardware that ships.

SEQ 01 — What we build

Five disciplines. One team. Zero hand-offs.

Most agencies stop at the browser. We go from the interface all the way down to the firmware — which means your web app, your automation, and the code running on your devices are built by people who actually talk to each other.

01WEB

Web design & development

Strategy-first websites and web applications — from a brand site that wins trust to a customer portal that runs your business. Designed in-house, built on modern stacks, and maintained after launch.

  • ›Marketing sites, e-commerce & portals
  • ›SEO, performance & accessibility
  • ›Hosting, security & care plans
02MOBILE

Mobile app development

Cross-platform apps that feel native — including offline-first field apps for teams that work where the network doesn't. One codebase, both stores, real support after release.

03SAAS

SaaS product engineering

Building a product is different from building a website. We take you from idea to a running, multi-tenant product — architecture, roles and permissions, billing, dashboards and deployment — and stay for the iterations that follow.

04AI

AI & automation

Practical intelligence built around real workflows — support bots your customers actually use on WhatsApp, document AI that runs on your own infrastructure, and automation that removes repetitive work without removing human control.

05R&D

Firmware & embedded systems

The discipline most software agencies can't offer. We work close to the metal — firmware analysis, protocol reverse engineering, embedded IoT — and connect it all the way up to cloud dashboards. If your product runs code on a device, we speak its language.

SEQ 02 — Who it's for

Different missions. Same launch team.

Find yourself below — each door leads to the work we've already done for teams like yours.

Founders & startupsI have a product idea. I need it real, fast.

We scope ruthlessly, build the smallest version that proves the idea, and iterate with you weekly. You get a working product and a team that thinks about your business, not just your backlog.

→ SaaS product engineering
Distributors & manufacturersMy operations run on spreadsheets, calls and WhatsApp forwards.

We've lived this world. Order-tracking systems, service workflows and AI support desks that replace the daily chaos with one source of truth — built for teams across departments and districts.

→ Order-tracking & support bot case studies
Growing businessesWe're serious now. Our website should say so.

A digital presence that earns trust — brand site, e-commerce, customer portal or mobile app — designed properly, launched on time, and looked after long after go-live.

→ Web design & mobile apps
Enterprise & industrialWe need proof before we commit to production.

Feasibility studies and working prototypes for hard problems — firmware, protocols, IoT pilots, private AI deployments. We turn uncertainty into an engineering decision you can defend.

→ Firmware & embedded research
SEQ 03 — Selected work

Launched and operating.

Real systems, in production, doing real work. Client names withheld where agreements require it.

AI support desk on WhatsApp

Solar equipment distributor · Live
Problem

Installers across multiple states flooded a single support line with the same questions — fault codes, warranty terms, commissioning steps. Engineers spent their day repeating answers instead of solving hard cases.

What we built

A WhatsApp bot trained on the company's inverter documentation. It answers fault-code and product queries instantly, and hands complex cases to the right service engineer based on the customer's state.

Result

Customers get accurate answers in seconds, 24/7. The support team now handles only exceptions — and every conversation is logged, searchable and consistent.

Order-tracking platform

Distribution business · SaaS · Live
Problem

Every order — from proforma invoice to dispatch — lived in emails, calls and memory. Sales didn't know what accounts had approved; the warehouse didn't know what was cleared to ship.

What we built

A role-based web application that tracks every order through its full lifecycle. Each department gets its own dashboard and approval step, with a complete audit trail on every document.

Result

One source of truth for the whole company. “Where is my order?” is now a glance at a screen, not a chain of phone calls between departments.

ReactNode.jsPostgreSQLRole-based dashboards

Solar fleet monitoring dashboard

Renewable energy · Web app
Problem

Installers managing distributed microinverter sites had no unified view — checking each site meant logging into separate tools and reading raw numbers.

What we built

A React dashboard on top of the manufacturer's cloud API: live generation data, per-site drill-downs, device status and alerts in one clean interface built for non-technical users.

Result

A whole fleet, readable at a glance. Underperforming sites surface immediately instead of waiting for a customer complaint.

Inverter firmware analysis

Power electronics · R&D
Problem

A deployed inverter platform needed to be understood from the inside — no source code, no schematics, no vendor documentation.

What we built

A full firmware programme: image extraction over JTAG, disassembly of the control logic, and CAN bus traffic analysis — producing a complete technical dossier of how the platform actually behaves.

Result

Findings that now inform a made-in-India power electronics roadmap. The kind of work that requires a team fluent in embedded code, not just applications.

SEQ 04 — How we launch

Every project is a countdown.

Our name is our process. Each phase clears the next — and nothing launches before it's ready.

T−5

Discover

We understand the problem before choosing any technology. Interviews, workflows, constraints.

T−4

Define

Ruthless scoping. What ships first, what waits, what we'll measure to call it a success.

T−3

Design

Wireframes to polished UI — reviewed with you before a single line of production code.

T−2

Build

Short cycles, working software every week. You watch it grow instead of waiting for a reveal.

T−1

Test

Real devices, real data, real users. Holds happen here — never after launch.

T−0

Launch

Liftoff. Deployment, handover, training — the moment thinking becomes a running system.

T+  ·  Operate — monitoring, support and iteration. The mission continues after liftoff.

SEQ 05 — Research & development

We investigate before you invest.

A standing internal R&D mandate keeps us ahead of the tools we deploy — and lets us take on feasibility studies most agencies would have to decline.

AI & ML

Applied artificial intelligence

Local and private LLM deployments, retrieval-augmented generation on sensitive documents, and computer-vision pipelines — evaluated hands-on, not from press releases.

Local LLMsRAGOpenCV
Firmware

Embedded systems & IoT

Firmware for edge devices, sensor networks and microcontroller platforms — written and proven in our own lab, then connected to high-throughput cloud pipelines for industrial use.

MicrocontrollersEdge computingC / C++
Infrastructure

Resilient cloud architecture

Serverless, containers and infrastructure-as-code — continuously audited so the systems we ship stay cheap to run and hard to break.

Read the research notes
Technology changes every year. Strong engineering doesn't.

We don't chase trends. Every decision we make — from architecture to deployment — follows one principle: build systems that remain valuable long after today's tools have changed.

That's why every engagement begins with understanding the problem, not choosing the technology. The best technology is almost invisible: it solves problems without creating new ones. And the right answer is rarely the newest one.

SEQ 06 — The people

Two engineers, one workshop.

T−0 is small on purpose. The people who scope your project are the people who build it — no account layer, no hand-off, no telephone game between you and the code.

The two founders of T−0 outside the studio in Kerala, India

Founded in Kerala by two engineers who kept ending up on the same problem from opposite directions — one from the browser down, one from the firmware up. T−0 is what that overlap turned into: a studio that can design an interface in the morning and read a firmware dump in the afternoon.

We stay deliberately small. Every project is worked by the people you meet in the first call, and every system we hand over is one we would be willing to maintain ourselves.
