What We Build
Six capability lines across the full web app lifecycle. Pick one or work with us across all six.
B2B Client Portals
Branded portals for suppliers, partners, vendors, and clients. Role-based access, invoicing, document sharing, real-time approvals, and status tracking — built around your exact workflow, not a generic template.
Internal Tools and Dashboards
Custom-built ops consoles, back-office workflows, and reporting dashboards on your exact data model. Everything Retool promises — fully owned, no per-seat pricing, no vendor ceiling on what it can do.
Enterprise Web Platforms
Custom CRMs, HRIS platforms, ERP extensions, and specialised compliance tools for the processes where off-the-shelf SaaS simply doesn't fit. Schema-up builds, never retrofitted from a template.
Legacy Modernization
Rescue ageing PHP, ASP.NET, or Rails applications. We rebuild on a modern stack with zero feature regression, a controlled cutover plan, and a documented migration path your team can maintain long-term.
Progressive Web Apps
Installable, offline-capable, push-notification-ready web apps — the fastest path to a mobile-feel experience without an App Store submission cycle or a separate native codebase to maintain.
Third-party Integration
Salesforce, HubSpot, Shopify, Xero, QuickBooks, Slack, Zapier, and custom REST/GraphQL APIs wired cleanly into your platform. Idempotent, observable, retried — integrations that don't silently fail at 2am.
Custom web apps, B2B portals, internal tools, and enterprise platforms — built with published scope, fixed pricing, and a committed delivery date.
Requirements workshop, user flow mapping, tech stack decision, and a signed scope doc before a single wireframe is drawn. You leave with a fixed price and a delivery date — not a rolling estimate that slips.
Wireframes, component library, and a production-ready Figma system. Every screen and every interaction approved by you before development starts — no mid-sprint design surprises.
Sprint-based development with weekly demos your team can click through. Full test coverage, CI/CD pipeline, and a staging environment you can access any time. Your feedback is logged and resolved before the next sprint opens.
Production deploy, performance tuning, observability wired (Datadog / Sentry / PostHog), and a 30-day post-launch warranty. We don't disappear after go-live — we're on call through the first month.

AI-Powered Customer Support SaaS Platform
A self-hostable, multi-tenant Laravel platform with semantic AI chatbots, support ticketing, knowledge base builder, and Stripe billing — a full alternative to Intercom and Crisp that clients own outright.
Freelance Marketplace Platform Launched in 8 Weeks
A fully operational freelance platform with escrow payments, bidding, dispute resolution, real-time chat, and Flutter mobile apps — shipped on schedule in 8 weeks.
On-Demand Home Service Marketplace
A location-aware marketplace connecting homeowners with service providers — Google Maps matching, real-time chat, WhatsApp notifications, multi-service cart, and Flutter mobile apps.
Classified Ads Platform with Live Chat
A full classified ads platform with location-based discovery, real-time buyer-seller chat, membership tiers, seller wallet, and a drag-and-drop CMS — trusted by 2,000+ brands.
eCommerce Platform with Built-In Courier
A complete eCommerce platform with automated courier label generation, fraud detection, dynamic variant matrix, multi-currency checkout, and multi-language storefront — no third-party logistics tools.
Security is Not a Phase Two Concern
Every engagement ships a DPA. Every architecture ships with a threat model — an honest roadmap, not marketing badges.

Real Questions. Real Answers.
The questions every web app buyer actually asks. If yours isn't here, ask it on the call — we'll answer it honestly.
A typical custom web app MVP takes 8–12 weeks on a fixed-scope plan — from signed scope doc to production launch. A more complex multi-role platform with third-party integrations and compliance requirements takes 12–16 weeks. We commit to a launch date in the proposal — not a rolling estimate that slips.
