Direct technical communication
Talk to the people responsible for your software — not a salesperson who relays messages to a project manager who relays them to a developer.
Custom software development company in India
ShawByte delivers custom software development services from Kolkata — build, improve, launch, and maintain software and SaaS with a technical partner who stays involved beyond the first release.
ShawByte is Shaw Udyog's founder-led software development studio. We take ownership of business software — not just tickets and hours.
Most companies already have software. The harder problem is getting it built, finished, and maintained with clear communication and real accountability. We sell responsibility: understand the problem, plan the change, ship it, and stay around when it needs to evolve.
Based in Kolkata, India, we work with businesses and product teams worldwide. Lean team. Direct communication. Strong engineering. Global delivery.
Why businesses choose ShawByte
Differentiation starts with the service experience — not buzzwords.
Visible progress
Clear milestones, shared boards, regular updates, and working demos. We show the product — not vague percentage-complete claims.
Ownership beyond coding
Understand, plan, build, test, deploy, maintain, and improve. Delivery does not end when the first release ships.
Long-term partnership
The goal is not a one-off handoff. We aim to become the technical partner you keep working with as the product evolves.
What we do
A focused portfolio — custom software, product work, rescue, retainers, and AI only where it earns its place.
Custom software
Systems shaped around real workflows — management tools, booking platforms, internal apps, dashboards, customer portals, and operational automation.
SaaS development
For startups and product teams: from idea and MVP through production readiness and ongoing product improvement.
Software rescue & modernization
Unfinished apps, vanished developers, aging PHP/Laravel systems, brittle architecture, painful deploys. We assess what can be fixed before you throw it away.
Ongoing development & maintenance
Bug fixes, dependency and security updates, performance, deployment, monitoring, new features, and steady technical support — the recurring layer after launch.
Practical AI integration
AI where it improves a real workflow — document processing, support assistance, knowledge search, reports, lead qualification, or features inside an existing product. Conventional software where that is better.
How we work
Ownership across the full software journey — not a handoff after the first deploy.
Understand
What you are trying to achieve, where the friction is, and what already exists.
Plan
What should change, what to build first, and what success looks like in production.
Build
Engineering with clear scope, visible progress, and early demos — not silent black-box delivery.
Test & launch
Quality checks, deployment, and a release you can actually run.
Improve
Stay involved for fixes, features, and the next iteration as the business changes.
Who we work with
Not everyone who needs software — teams that need a reliable technical partner.
Startups & SMEs
Teams that need a reliable technical partner — building SaaS, finishing an unfinished product, modernizing what they have, or continuing development without a full in-house engineering team.
Agencies needing engineering capacity
Digital and software agencies that already have the client, design, and brief — and need a dependable development partner to execute.
