What we build

Custom software development, by service.

AI chatbots & conversational agents
Workflow & process automation
LLM integration (OpenAI, AWS Bedrock, LangChain)

02.

Web & SaaS Development

Production web applications and multi-tenant SaaS platforms built with React and Next.js.

03.

MVP Development for Startups

A working, testable product built fast — scoped to what proves your idea, not everything you can imagine.

Product scoping & technical planning
Fixed-timeline MVP builds
Weekly demos on a staging URL

Software that replaces spreadsheets and manual processes with systems your team actually wants to use.

Internal dashboards & admin panels
Third-party & API integrations
WhatsApp Business API & Razorpay integrations

05.

Cloud Infrastructure

Infrastructure sized and configured for your actual traffic — not over-engineered, not fragile.

AWS deployment & architecture
Docker & Kubernetes orchestration
CI/CD pipelines & monitoring

06.

Mobile Apps

Cross-platform apps from a single codebase, shipped to both app stores.

Flutter & React Native development
iOS & Android from one codebase
App store submission & release management

How we work

Concrete practices, not promises.

Specific commitments you can hold us to on every engagement.

Typed, Tested Code

TypeScript across the stack, automated tests on critical paths, and code review on every change.

AI Built In, Not Bolted On

When AI is part of the scope, it's designed into the architecture from day one — not added later as a widget.

Architecture Sized to You

Infrastructure and data models scoped to your actual traffic and team size — not over-built for hypothetical scale.

Weekly Staging Demos

You see working software on a live URL every week, from the first sprint — not a status report.

Fixed Scope, Fixed Quote

A written scope and price agreed before a line of code is written. Changes are quoted, not silently absorbed.

Direct Line to the Engineer

You message the person writing your code — no account manager relaying updates.

Security by Default

Auth, secrets management, and input validation handled as standard practice, not an add-on request.

Documented Handoff

Clean repo, infrastructure-as-code, and README-level documentation — your team can take over anytime.

Our process

From concept to deployment.

A structured approach that ensures quality at every stage — with concrete deliverables you can hold us to.

Discovery

We understand your business, goals, users, and technical requirements.

Internal products and concept builds we designed, architected, and shipped ourselves — so you can inspect exactly how we think and build.

INTERNAL PRODUCT · VOICE AI · SAAS

Voice AI Platform for Indian SMBs

Problem — SMBs miss customer calls outside business hours and can't afford a multilingual answering service.

Solution — AI voice agents that answer in Telugu and Hindi on Indian phone lines, with native STT/TTS, Vobiz telephony, and automated per-customer Razorpay billing.

INTERNAL PRODUCT · WHATSAPP · CRM

WhatsApp CRM for Lead Management

Problem — Leads arriving over WhatsApp get lost without a system to qualify and follow up automatically.

Solution — A WhatsApp-first CRM that captures, qualifies, and follows up with leads using AI-assisted conversations, built on open-source foundations with a proprietary AI and WhatsApp layer.

CONCEPT PRODUCT · E-COMMERCE · PWA

White-Label Storefronts for Instagram Sellers

Problem — Instagram sellers depend on DMs and manual payment links, with no real storefront of their own.

Solution — Branded PWA storefronts with subdomains and split payments, turning sellers into independent store owners without app-store friction.

CONCEPT PRODUCT · CIVIC TECH · WHATSAPP

WhatsApp-First Civic Grievance CRM

Problem — Citizens have no simple, low-literacy way to report civic issues, and officials lack a system to track resolution.

Solution — A civic CRM where citizens report grievances over WhatsApp in their own language, AI triages and routes them, and officials track resolution — pitched to a state urban innovation challenge.

Rajkumar

Founder & Software Engineer

Wintra Softworks is a founder-led software engineering studio focused on building modern digital products for startups and growing businesses.

Every engagement gets hands-on technical leadership, not delegated execution. The work starts with understanding the business problem — what the software needs to do, for whom, and why — before any technology decisions are made. Clean architecture, scalability, maintainability, and performance aren't afterthoughts; they're the baseline for every build.

Wintra stays founder-led on purpose. It means faster decisions, fewer communication layers, and a single point of accountability for the quality of what gets shipped.

“Great software isn't just built with the latest technologies — it's built by deeply understanding the problem first.”

FAQ

Frequently asked questions.

What types of companies do you work with?

Startups, SMBs, and established companies adding AI to existing systems — if you need requirements shipped as working software, we're a fit.

You're a new studio — why should I trust you with my product?

Our work section shows products we designed, architected, and shipped ourselves, and you get working software on a staging URL every week from day one.

How do you approach a new project?

Discovery produces a written scope and fixed quote before any code is written, then we build in weekly, demoable increments.

What is your typical project timeline?

A focused MVP typically takes 8–12 weeks; more complex platforms can take 4–6 months.

How does pricing work?

Every project is scoped to a written quote and billed by milestone rather than by the hour, with changes quoted before we build them.

How do you handle communication during projects?

Direct WhatsApp or Slack access to the engineer building your product, with weekly staging demos — no account managers relaying messages.

What if we're not sure which technologies to use?

We recommend the most suitable stack for your requirements, scale, and budget, and explain every recommendation.

Do you provide ongoing support after launch?

Yes — every build includes a post-launch fix window and full handoff documentation, with optional maintenance and retainer arrangements after that.
