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

Specialist in Flutter, React Native, FastAPI, and cloud engineering for founders, product teams, and agency partners building products for a worldwide audience.

What we build

Three pillars. One team across the stack.

Tap a pillar to see the deep dives, the stack, and how we pick between the alternatives.

Mobile App Development Services

Cross-platform apps on Flutter or React Native. Two honest options, one review, one deploy pipeline.

Deep dives

Flutter App Development Services

Flutter apps for iOS, Android, iPad, and web from one Dart codebase. Named state management, typed backend contracts, store pipelines that ship on a Tuesday.

React Native App Development Services

React Native for teams already writing React and TypeScript. New Architecture, Expo, OTA updates, native modules when a library falls short.

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. Each 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

Discover

  • Two-week scoping sprint, live overlap with your hours.
  • You leave with a written spec, architecture plan, and a build quote.
  • Not a sales pitch.
Stage 02 / 05 Blueprint locked

Architect

  • Data model and service boundaries agreed up front.
  • Infrastructure and deployment pipeline documented.
  • Nothing hits production until the plan is locked.
Stage 03 / 05 Two-week cadence

Build

  • Short sprints on a two-week cadence.
  • Live demos every fortnight.
  • Course-correct as we go, with no surprises at the end.
Stage 04 / 05 Test · release · monitor

Release

  • Functional testing across flows, devices, and edge cases.
  • App Store and Play Store submission handled.
  • Deployment, CI/CD, and staged rollout.
  • Observability is wired in from day one.
Stage 05 / 05 24×7 · iterate

Support

  • We stay after launch.
  • 24×7 monitoring and fast fixes.
  • Iteration as your product grows.

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 projects in Flutter, React Native, Node.js, and Python. 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.
