You’ve planned the product. Plans don’t run in production. We engineer the software that does.

Specialist Flutter, React Native, FastAPI, and cloud engineering for founders, product teams, and agency partners with products for a global audience.

What we build

Three pillars. One team across the stack.

Mobile App Development

Cross-platform apps that feel native on every device. Flutter and React Native, architected cleanly, tuned for offline, payments, and push.

Backend & APIs

Typed, tested APIs that hold up under load. FastAPI and async Python for products that start at ten users and survive a million.

Web & Admin Panels

Fast, accessible interfaces for products and teams. React and Next.js work: customer sites, internal consoles, and admin panels built to grow.

Pillar 01 · Mobile App Development

Mobile apps that earn their place on the home screen.

Cross-platform: Flutter or React Native, whichever actually fits your product and your team.
Clean architecture: state management that scales with you, using BLoC, Riverpod, Redux Toolkit, or Zustand.
Offline-first: the app keeps working when the network doesn’t, then syncs cleanly when it’s back.
Payments, wired in: Stripe, Apple Pay, Google Pay, and PayPal for global markets, plus RazorPay, PhonePe, and Paytm for Asia-Pacific, with in-app purchases on iOS and Android.
Notifications & deep links: FCM, APNs, universal links, and Firebase / Supabase integration done right.
AI-ready: on-device models and API-backed features, wired into real user flows instead of bolted on.
Ship and survive: App Store and Play Store submission, plus the maintenance, rollouts, and bug triage that come after.
Plug into your team: full product build, a single Flutter or React Native pillar, or embedded engineers inside your repos and sprint cadence, with agency-partner engagements welcome under NDA.

Pillar 2.1 · Backend & APIs

Typed APIs and async Python that don't fall over at scale.

FastAPI-first: typed endpoints, async Python, and Pydantic validation, so fewer runtime surprises.
Right protocol for the job: REST, GraphQL, or WebSockets, whichever the product actually needs.
Secure by default: OAuth2 + JWT auth, rate limiting, CORS, CSRF, and audit logs baked in from day one.
Real background work: Celery and Redis queues for jobs, retries, and schedules, not cron hacks on a forgotten box.
Tests that actually run: pytest, honest mocks, and CI gates that block bad merges before they land.
Portable deploys: Docker and Kubernetes on AWS, GCP, or DigitalOcean, with no vendor lock-in.
Observability from day one: Prometheus, Grafana, and ELK wired in before launch, so you see problems before users do.
Fits your team: greenfield FastAPI builds, a single new service, or takeover of an existing Python or Node backend, scoped to where you actually need the help.

Pillar 2.2 · Database

Data layers that stay honest as the product grows.

Relational: PostgreSQL and MySQL for structured data that outlives the app and the team that wrote it.
NoSQL: MongoDB for flexible documents, Redis for caching and realtime sync that actually holds up under load.
Vector & AI search: Pinecone and pgvector for semantic search, RAG pipelines, and recommendations.
Safe migrations: schema changes that don’t break production on a Friday evening. Reversible, staged, and reviewed.
Built to scale: read replicas, connection pooling, and backup strategies we actually restore from, not just configure.
Bring your own: whatever database you already run, we plug into your existing stack without a rewrite.

Pillar 03 · Web & Admin Panels

Web and admin interfaces that don't fight the team using them.

React & Next.js: marketing sites, authenticated product surfaces, and internal admin panels, all on one toolchain.
Design systems: Tailwind, Material UI, or Chakra, whichever your team already speaks. No rewrite to whatever we prefer.
Rendering strategy: SSR and SSG where performance matters, CSR where it doesn’t. We pick per page, not per project.
Real forms: Formik, React Hook Form, and Yup for validation that handles the edge cases your users will actually find.
Accessibility baked in: WCAG AA or better from the first component, not bolted on before a compliance review.
Automated tests: Jest, React Testing Library, and Cypress, so nothing regresses quietly between sprints.
Ship confidently: CI-driven deploys to Vercel, Netlify, or AWS. Friday 5pm releases without the pager.
Third-party integrations done right: Stripe, PayPal, Twilio, SendGrid, Intercom, Segment, social auth, CRM wiring, and LLM APIs, plumbed cleanly into your flows.

How we work

Five steps. No mystery.

A disciplined pipeline from first call to long-term care. Every stage has a defined output, so you always know what you’re paying for and what you’ll get next.

01 Discover 02 Architect 03 Build 04 Release 05 Support

Stage 01 / 05 Spec + plan

Architect

Data model and service boundaries agreed up front
Infrastructure and deploy pipeline documented
Nothing hits production until the plan is locked

Stage 03 / 05 Two-week cadence

Build

FAQ

What founders, product teams, and agency partners ask us.

Most projects run eight to sixteen weeks. We occasionally take on short audits or architecture reviews.

Fixed-price once the architecture is locked. Hourly during discovery or for ongoing maintenance.

You do. All intellectual property, all repositories, all cloud accounts in your name.

Yes. Mutual NDA before we get into specifics.

Yes. We've inherited Flutter, React Native, Node, and Python projects. Every takeover starts with a written audit.

LLM APIs (OpenAI, Anthropic, Google), local models via Ollama, RAG pipelines, vision, and voice. Integrated cleanly, not bolted on.

Yes. Play Store and App Store submission, review responses, staged rollouts, and ongoing releases are part of every mobile engagement.

Yes. We partner with agencies globally on Flutter, React Native, FastAPI, and cloud engagements. Mutual NDA first, IP assigned to your agency, delivery under your brand, and we never approach your clients directly.

Yes. Most of our founder clients don't have one yet. Our discovery sprint is designed for this: we translate your product into a written spec, a data model, and a build plan you can hand to any future CTO.

Yes. Payments (Stripe, PayPal, Apple Pay, Google Pay, RazorPay, Paytm), auth (Auth0, Clerk, Firebase), comms (Twilio, SendGrid, Intercom), AI (OpenAI, Anthropic, Google), social logins, CRM, and analytics, plumbed cleanly into your flows, not bolted on.
