WHAT WE BUILD · SERVICES

Building softwarethat scales.

Web3, SaaS, and the systems behind them.

WEB3

Two services. One discipline.

01–02

01 / 06Smart Contract Development

THE PROBLEM

Most smart contracts ship with subtle vulnerabilities.

Reentrancy, integer overflow, oracle manipulation — attackers find what auditors miss. One exploit drains the protocol and ends the project.

THE SOLUTION

We write contracts the way auditors write reviews.

Clean state machines, explicit access control, invariant checks at every boundary. Foundry test suite at 100% coverage. External audit hand-off before any mainnet deploy.

10 require(msg.sender == owner);
11 payable(owner).transfer(balance);

✓ Audited✓ Gas optimised

THE PROCESS

  1. 01

    Spec & threat model

    Attack surface, economic incentives, boundary conditions.

  2. 02

    Implementation

    Solidity + Foundry + invariant tests.

  3. 03

    Internal review

    Slither + manual walkthrough + gas analysis.

  4. 04

    Audit & deploy

    External audit hand-off. Mainnet deploy + monitoring.

02 / 06dApp Development

THE PROBLEM

Most dApps feel like contracts wrapped in HTML.

Users drop off at wallet connect, the gas fee confirmation, or the pending transaction screen. The UX punishes users for using Web3.

THE SOLUTION

We build dApps where Web3 disappears into the UX.

Clear states, predictable signing, optimistic updates, and fallbacks for every chain hiccup. Wallet integration that feels inevitable, not technical.

THE OUTCOMES

Connected

Wallet UX that doesn't lose users at connection.

Reactive

Optimistic updates, pending states, and error recovery.

Monitored

On-chain alerts before issues become incidents.

THE PROCESS

  1. 01

    Architecture

    Wallet strategy, chain selection, state management.

  2. 02

    Frontend build

    Next.js + Wagmi + RainbowKit.

  3. 03

    Contract integration

    Viem, typed ABIs, full test coverage.

  4. 04

    Mainnet launch

    Testnet → mainnet, monitoring, docs.

SAAS

Two services. One platform.

03–04

03 / 06SaaS Product Development

THE PROBLEM

Most SaaS products break under their own success.

Schemas tangle. Auth gets bolted on. Performance degrades. The refactor takes quarters and costs a round of funding.

THE SOLUTION

We architect for the version that has 100K users.

Clean domain boundaries, observable systems, deploy-on-merge. Multi-tenant from the start. Billing infrastructure, not billing scripts. You ship features, not fires.

THE PROCESS

  1. 01

    Domain modeling

    Tenants, roles, billing model, scale targets.

  2. 02

    Foundation

    Auth, billing, infra — done right once.

  3. 03

    Core build

    Two-week sprints. Demos every Friday.

  4. 04

    Polish & launch

    Observability, load test, hand-off or stay.

04 / 06MVP Launch

THE PROBLEM

Most founders ship their MVP six months too late.

Endless scope creep, polish before product-market fit, and the wrong stack for the job. By the time they launch, the market has moved or the runway has ended.

THE SOLUTION

Six weeks. Real users. Fixed scope.

We build the smallest version that proves the thesis. Auth, payments, core flow, working in production by week six. No feature theater. No design polish that doesn't ship value. Just the product, in users' hands, learning fast.

IT SERVICES

Two services. One craft.

05–06

05 / 06UI/UX Design

THE PROBLEM

Most designs survive review and die in production.

Edge cases not considered. Empty states forgotten. Mobile thrown in at the end. Users notice every gap within seconds.

THE SOLUTION

We design every state before the first pixel ships.

Loading, empty, error, success — all designed. Components are systems, not screens. Every interaction has a spec. Handoff includes motion, not just Figma files.

Wireframe

Mid-fi

Hi-fi

THE PROCESS

  1. 01

    Research & flows

    User journeys, information architecture, edge cases.

  2. 02

    Wireframes

    Structure, flows, layout — validated early.

  3. 03

    Visual system

    Color, typography, components, spacing rules.

  4. 04

    Hi-fi & handoff

    Prototype, motion specs, developer handoff.

06 / 06Mobile App Development

THE PROBLEM

Native apps cost double. Web wrappers feel cheap.

And users notice the difference within seconds. The wrong platform choice early costs you months of rewrites and App Store rejections.

THE SOLUTION

We build with React Native where it works, native where it matters.

Same codebase, same team, same ship date. iOS and Android from a single React Native repo — with native modules where performance demands it.
