We design, build, and ship production-grade web platforms, mobile apps, and AI-powered products for startups, SMEs, and growing enterprises across the US, UK, UAE, Canada, and Australia. Led by founder Jazib Qureshi (10+ years in software delivery), our team operates as an embedded product partner, not a ticket queue. That means one accountable team across strategy, design, engineering, AI, and growth, instead of handoffs between vendors. 🔹What we build: 🔹 Web & Custom Software: ➜ React, Next.js, Node.js, NestJS, Laravel, Python/FastAPI, PostgreSQL, MongoDB. SaaS platforms, internal tools, CRM/ERP systems, REST & GraphQL APIs. 🔹Mobile Apps: ➜ Native iOS, Native Android, Flutter, React Native. Real-time features, offline support, push notifications, App Store/Play Store launch support. 🔹AI & Automation: ➜AI agents, RAG pipelines, LLM-powered features (OpenAI, Claude, Gemini), MCP integrations, chatbots, voice AI, and workflow automation (n8n, Zapier, Make) that removes manual work from real business processes. 🔹Cloud & DevOps: ➜AWS, Azure, Docker, Kubernetes, CI/CD pipelines, and infrastructure built to scale without a rewrite at 10x traffic. 🔹Design & Branding 2D/3D animation: ➜ Product strategy, UI/UX, dashboard design, branding, motion graphics, and 2D/3D animation —because software that looks unfinished loses trust before a user reads a word of copy. ➜ Explainer videos, product animations, and marketing motion content that make complex products easy to understand and easy to sell. 🔹How we work: ➜Discover → Design → Build → Grow. Weekly demos, daily async updates, and clear milestones, you always know exactly where the work stands. Free 30-minute strategy call for projects $3,000+. Tell us what you're building — we'll map the approach, the stack, and a realistic timeline before you spend a dollar. Message us to get started. 🔹Why Choose Us: ➜ One accountable team. Strategy, design, engineering, AI, and growth under one roof — nothing lost in vendor handoffs. ➜ Founder-led delivery. Direct access to the person accountable for outcomes, not just output. Process before code. We pressure-test the problem and map the path before a single sprint starts. ➜ Built to scale. Architecture designed to grow from MVP to multi-market without a rewrite every quarter. ➜ Radical transparency. Weekly demos, live documentation, honest trade-offs. ➜ Global-ready. We work across US, UK, UAE, Canadian, and Australian time zones with clear overlap windows. Message us here to start. less -
