Coming soonLanguage technology

VaakBoard

A Hycyon product · Web demo · iOS (coming soon)

A precision input system for Sanskrit and Devanāgarī, built around how the language is actually written — not a layout with letters swapped.

Latin and IAST to Devanāgarī, and back, with conjuncts, matras, anusvāra and visarga
Deterministic rules: the same input always gives the same output
Tested engine, shared by the web demo
Native iOS keyboard in preparation

Future

The next one

Hycyon is building continuously. New products appear here when they are real.

Services

Built for your ideas. Built for your business.

The same team that ships Hycyon's own products builds yours.

Websites

Fast, clear sites for businesses, creators and organisations — designed to be found and easy to trust.

Web Applications

Accounts, dashboards and workflows that turn a process into a product people use daily.

Mobile Applications

Android and iOS apps, from first prototype to a backend-powered release.

Custom Software

Tools shaped around how you actually work, when nothing off the shelf fits.

AI & Intelligent Systems

Assistants, document Q&A and AI features built into products with the keys kept server-side.

Product Development

From concept to a shipped product — the way we build our own.

Automation & Integrations

Browser extensions, APIs and connectors that remove repetitive work.

Selected work

Built for clients, with the same care.

Each project is described by the problem it solved and what was built. Outcomes appear only when they are real.

Client projectArchitectural & decorative ironwork

iron's irony

The problem: A fabricator whose product is custom and site-specific had no way for a homeowner or architect to start a conversation without already knowing what to ask for.
The thinking: A site organised around the five stages of the work — measure, design, fabricate, finish, install — and a Start a Project flow that accepts a photo, a sketch or a rough measurement instead of a finished brief.
What was built: Next.js and TypeScript site with its own visual identity, separate from Hycyon
Server-validated enquiry flow with spam and rate protection, and WhatsApp, phone and email fallbacks
Rule-based project assistant that answers only from the site and never quotes prices
A feedback page where past customers share how it went; nothing is published until the owner confirms it and the person agrees
Structure ready for real project photography — none of it invented
What comes next: Real installations, photographs and customer words. Until they exist, the site shows labelled representative drawings and an empty feedback wall.

Why Hycyon

Client work, held to a product standard.

Build and product

Hycyon does not only build for clients. It ships its own products, so client work is held to a product standard.

Engineering and design

Technology and the experience of using it are decided together, not handed from one team to the next.

Product thinking

The goal is not to deliver code. The goal is to build something useful to the person using it.

Technical depth

Web, mobile, backend, on-device machine learning and AI — within one codebase and one team.

Continuous experimentation

Products evolve through experiments, and the experiments are allowed to be unusual.

Engineering

See what's under the hood.

Hycyon is built by engineers who don't stop at the interface. The engineering portfolio shows the projects, the code and the thinking behind them.

Explore the engineering portfolio

From interface to infrastructure.

Web: Static-first sites and web apps, Tailwind and vanilla HTML/CSS/JS, zero-dependency builds.
Mobile: Flutter and Dart apps for Android and iOS, with offline-first libraries and local notifications.
Backend: Node.js on Firebase Cloud Functions (2nd gen), callable APIs, Firebase Auth.
AI: Google Gemini behind a serverless proxy, retrieval-style summaries, AI tutoring flows.
Data: Firestore with security rules and indexes, conflict-preserving sync across devices.
Infrastructure: Firebase Hosting, GitHub Pages, Google Cloud Secret Manager for credentials.
Native: Swift, SwiftUI and CoreData on iOS, including a custom keyboard extension.
Product architecture: On-device OCR and translation with Google ML Kit, spaced-repetition scheduling, a single source of truth per product.

Prototype

Sanskrit input engine

The language engine behind VaakBoard: Latin and IAST to Devanāgarī and back, covered by an automated test suite and running in a web demo. Language detection, suggestions and correction are not built yet — the roadmap says so.

Try the demo

Experiment: An idea tried to see what happens.
Prototype: Works well enough to test with people.
Research: Understanding before building.
Product: Shipped, supported and maintained.

About

Why Hycyon exists.

Technology is a tool for turning ideas into things people can actually use.

Hycyon exists to build useful software, create products people return to, explore technology without a deadline, and solve real problems — whether they are ours or yours.

Based in Varanasi, India, Hycyon is young and building continuously. What it has built so far is the proof: two live products and the engineering behind them.

The builder

Abhishek Sharma

Founder · Engineer · Product Builder

Built by an engineer who cares about the details. Abhishek works across the stack — Flutter and Firebase, Swift on iOS, the web — and studies Sanskrit and Vedic literature alongside computer science.

That intersection of language and computation produced VaakBoard, a native Sanskrit keyboard for iOS, and it shapes how Hycyon thinks about products: precise, unconventional where it matters, useful first.
