Spotlight: Web Applications

Full-Stack Apps That Don't Break Under Pressure

Most agencies write code that works in demo conditions. We write code that survives production โ€” Black Friday traffic, concurrent users, and edge cases you didn't think of.

Every web application we build goes through our 5-layer quality gate before delivery: unit tests, integration tests, end-to-end tests, security audit, and performance benchmarking.

Core Web Vitals optimised โ€” LCP < 2.5s, CLS < 0.1, FID < 100ms
OWASP Top 10 security hardening on every project
Role-based access control (RBAC) with audit logging
Real-time features via WebSockets or Server-Sent Events
Progressive Web App (PWA) ready โ€” works offline

How We Work

Our 6-Phase Development Process

A transparent, collaborative process that eliminates surprises and keeps you in control at every step.

01
1โ€“3 days

Discovery & Requirements

We start with a deep-dive workshop (in-person in Bengaluru or via video call) to understand your business goals, user needs, and technical constraints. Output: a detailed Requirements Specification Document (RSD) that becomes our contract.

Stakeholder interviews User journey mapping Competitor analysis Technical feasibility RSD document
02
1โ€“2 weeks

UI/UX Design

Our designers create wireframes and high-fidelity mockups in Figma. We don't start coding until you've approved every screen. This phase catches 90% of scope issues before a single line of code is written.

Wireframes (lo-fi) User flows High-fidelity mockups Interactive prototype Design system
03
3โ€“5 days

Architecture & Setup

Before building features, we establish the technical foundation: database schema, API contract, infrastructure design, CI/CD pipeline, and coding standards. Skipping this phase is why projects go over budget.

DB schema design API contract (OpenAPI) Repo + branch strategy CI/CD pipeline Dev/staging environments
04
4โ€“16 weeks

Agile Development

We work in 1-week sprints with a demo call every Friday. You see real progress weekly โ€” not a big reveal at the end. Every sprint delivers tested, deployed-to-staging features you can click through and give feedback on.

Weekly sprint planning Friday demo calls Staging deployment Client feedback loop Code review every PR
05
1โ€“2 weeks

QA & Testing

Our dedicated QA engineers run the project through unit tests, integration tests, cross-browser/device testing, performance profiling, and a security audit before anything touches production.

Unit + integration tests Cross-browser testing Mobile responsiveness Performance audit (Lighthouse) OWASP security scan
06
3โ€“5 days

Launch & Handover

We manage the production deployment, configure monitoring and alerting, and conduct a live training session with your team. You receive a full handover package: source code, docs, deployment runbook, and admin credentials.

Case Studies

Real Projects, Real Results

A glimpse at what we've built for clients across India and internationally.

HealthTrack โ€” Hospital Management System

A 150-bed private hospital in Pune needed to replace their legacy desktop software with a cloud-based system their doctors could access on any device.

Challenge

Paper-based processes caused billing errors of โ‚น8 lakh/month. Legacy software crashed 3โ€“4 times per week during peak OPD hours.

Solution

We built a full HMS on Laravel + React with modules for OPD, IPD, pharmacy, billing (ABDM-ready), lab reports, and doctor scheduling. Deployed on AWS with 99.9% uptime SLA.

Results

Billing errors dropped 94%. OPD queue time reduced from 45 min to 12 min. Hospital saved โ‚น96 lakhs in the first year.

QuickMart โ€” B2B Wholesale Platform

A Delhi-based FMCG distributor serving 2,000+ retailers needed a self-service ordering platform to reduce their 12-person order entry team.

Challenge

Retailers placed orders via WhatsApp and phone โ€” error-prone and slow. The distributor couldn't scale without hiring more staff.

Solution

Built a mobile-first PWA where retailers browse catalogues, place orders, track deliveries, and view account statements. Backend integrates with their existing Tally ERP via a custom API bridge.

Results

78% of orders now placed digitally. Order entry headcount reduced from 12 to 3. Order processing time cut from 4 hours to 8 minutes.

EduPulse โ€” EdTech SaaS

A Bengaluru startup needed to build an LMS SaaS that could onboard 1,000 coaching institutes under white-label plans within 6 months of launch.

Challenge

Needed multi-tenancy, custom domain support per institute, live classes via video, recorded content, quizzes, and payments โ€” all within a tight MVP budget.

Solution

Built a multi-tenant SaaS on Django + React. Each institute gets their own subdomain, branding, and data isolation. Integrated Agora for live classes, Razorpay for fee collection, and S3 for video hosting.

Results

Launched in 18 weeks. Onboarded 340 institutes in 3 months. MRR reached โ‚น8.2 lakhs within 6 months of launch.

FAQ

Software Development Questions Answered

Use off-the-shelf software (Shopify, Salesforce, Zoho) if your processes fit the standard workflow. Build custom when you have unique business logic, need deep integrations with existing systems, or the SaaS subscription will cost more than a custom build within 2โ€“3 years (common at 20+ users).

A rough description of what the software should do is enough for a ballpark figure. For an accurate quote, we need: target users, core features list, any existing systems to integrate with, preferred technology (if any), and timeline. We help you create this in our free discovery call.

Absolutely. You own 100% of the code, database schemas, and all assets. We hand over the full Git repository, documentation, deployment scripts, and all credentials. We have no licensing fees, no lock-in, and no strings attached.

We document all scope changes and send a formal Change Request (CR) with cost and timeline impact before proceeding. Small changes (< 2 hours) within a sprint are often absorbed. We never surprise you with invoices.

Yes โ€” we regularly do code audits and take over existing projects. We'll do a free technical audit first and give you an honest assessment of what we're working with before committing to a fixed price.

Yes, always. We sign NDAs before the first detailed technical discussion. Your idea, business logic, and data are fully protected.

We are GST-registered (GSTIN provided on request). All invoices include GST at 18%. We accept NEFT, IMPS, UPI (PhonePe/GPay), and Razorpay. International clients pay via wire transfer or Stripe.
