Software · Design · Engineering
Isai’s Logic is a software studio. We design and engineer digital products — mobile apps, web platforms, business software and automation — from the first question to the version that ships next year.
Five products across culture, consumer, industry and operations. Every one designed and engineered in-house.
A Tamil calendar that respects the tradition it carries.
A Tamil calendar built for daily use — months, festivals and daily timings presented with the clarity of a modern interface and the typographic care the language deserves.
View projectA digital astrology experience where charts, planetary positions and readings are computed carefully and presented as a considered interface — legible, calm, and free of the clutter the category is known for.
View projectA centralised pet-care companion. Vaccination schedules, deworming, vet visits and pet records live in one calm timeline — so owners stop keeping it in their heads, and in photographs of paper cards.
View projectA commerce and catalogue platform for the rapier loom spare-parts ecosystem — built for buyers who search by part, machine and compatibility rather than by browsing a storefront.
View projectA digital canteen platform covering both sides of the counter — ordering for staff, and menu, queue and fulfilment management for the people running the kitchen.
View projectCode is the last step. These are the decisions that came before it — and the reason each product works the way it does.
A Tamil calendar that respects the tradition it carries.
Tamil calendars online are mostly scanned almanac pages — dense, cramped and hostile on a phone. People pinch, zoom and squint to find one line of information they check every single day.
We treated it as an information design problem, not a porting exercise. We mapped what people actually look up, how often, and in what order — then built the hierarchy around that instead of reproducing the printed page.
A restrained palette, generous spacing and a type scale tuned for Tamil script. Festival days carry weight without shouting. Motion is limited to orientation — where you are in the month, and where you just came from.
A calendar that feels culturally faithful and unmistakably modern — quick enough to open, glance at, and close.
Pet owners keep vaccination dates, deworming cycles, vet visits and medical history across paper cards, camera rolls and memory. The information only matters at the exact moment it cannot be found.
We modelled the pet — not the appointment — as the centre of the product. Every record hangs off an animal's profile, and every record knows when it is due again.
A soft, warm system with a single sage accent so health states read instantly: due, overdue, done. Cards give way to a continuous timeline, because care is a sequence rather than a list.
A pet-care product owners actually maintain, because logging takes seconds and the app does the remembering.
Buying rapier loom spares runs on phone calls, PDFs and part numbers written on paper. Ordering the wrong component costs a mill far more than the part — it costs downtime.
We designed for confirmation rather than discovery. Every path through the catalogue ends with the buyer certain that this part fits that machine, with the specifications visible beside it.
Dense but ordered layouts, tabular specification blocks, a steel-and-graphite palette, and typography that holds up when a screen is full of part numbers.
A B2B platform with the precision the industry requires and the clarity consumer commerce taught everyone to expect.
Most projects touch more than one of these. We scope the pieces that matter and leave out the ones that do not.
Consumer and business applications for iOS and Android, designed for the way people actually hold a phone.
Dashboards, portals and platforms that stay fast and legible as the data behind them grows.
Research, information architecture, interface design and design systems — the work that happens before code.
Internal tools built around how a business actually runs, rather than around a generic template.
Removing the manual steps between systems, so work moves without someone re-typing it.
Storefronts and B2B catalogues engineered for real inventory, real pricing and real buyers.
Language models applied where they genuinely improve a product — not bolted on as a feature.
The same sequence on every engagement. You always know which stage we are in and what comes out of it.
We learn the business, the users and the constraints before proposing anything.
Scope, architecture and success criteria — written down while they are still cheap to change.
Flows, interface and system. Decisions get made in design, not discovered in development.
Engineering in short, reviewable increments against a clean, scalable architecture.
Release, instrumentation and the operational detail that makes a launch uneventful.
Products earn their value after launch. We keep shaping them with what the usage tells us.
A stack is a set of trade-offs. We pick per project — for the problem, the team that will maintain it, and the decade it has to survive.
We take on work we intend to be responsible for. That single constraint shapes everything below it.
