Product Engineering & AI

Apps, backends, AI systems.
Built to ship, not to demo.

We design and ship mobile apps, backend platforms, and AI systems for teams that need production software — without the fluff, without the wait.

What We Do

Design, engineering, and AI — one accountable team

Product design, web and mobile engineering, AI features, and QA, run by the same people from kickoff to release — not handed between vendors.

UI/UX Design

Research-backed product design that turns complex workflows into clear, on-brand interfaces.

  • Product & UX strategy
  • Wireframes & prototypes
  • Design systems
  • Usability testing

Web Development

Fast, accessible, SEO-ready web apps — from marketing sites to complex SaaS platforms.

  • Custom web applications
  • E-commerce platforms
  • CMS & headless builds
  • API & third-party integrations

App Development

Native and cross-platform mobile apps engineered for performance across iOS and Android.

  • iOS & Android (native)
  • Cross-platform (React Native/Flutter)
  • App Store & Play Store release
  • Offline-first & push notifications

AI & Automation

LLM features, retrieval pipelines, and internal automation — built into the product, not bolted on afterward.

  • LLM-powered features (chat, search, generation)
  • RAG & retrieval pipelines
  • Workflow & internal-tool automation
  • Model evaluation & guardrails

QA & Testing

Dedicated QA embedded in every sprint, so bugs are caught before your users find them.

  • Manual & exploratory testing
  • Test automation (E2E, API, unit)
  • Performance & load testing
  • Security & accessibility audits

How We Work

Five stages. No surprises.

The same five stages on every engagement, whether we're shipping a feature or standing up an AI system from scratch.

  1. Step 1

    Discover

    We map goals, users, and constraints into a clear scope and timeline.

  2. Step 2

    Design

    Wireframes to polished UI, validated with you at every step.

  3. Step 3

    Develop

    Agile sprints, clean commits, and demos you can click through.

  4. Step 4

    Test

    Dedicated QA runs manual and automated checks before anything ships.

  5. Step 5

    Deploy & Support

    Smooth release, then monitoring and support to keep it running.

Why JS Solutions

Built for teams who can't afford rework

A software partner that treats quality assurance as part of delivery, not an afterthought.

One cross-functional team

Design, engineering, and QA sit in the same sprint — no hand-off gaps, no lost context.

QA built in, not bolted on

Every feature is tested before it reaches you, not after a client bug report.

Stack-agnostic delivery

We match the technology to your product and existing codebase — not our comfort zone.

Transparent communication

Weekly demos, shared boards, and direct access to the people building your product.

Predictable timelines

Fixed-scope estimates and sprint-based tracking keep delivery dates realistic and visible.

Support after launch

Monitoring, fixes, and iteration once you're live — we don't disappear after go-live.

Engagement Models

Three ways to work with us

Every engagement includes design, development, AI, and QA — only the structure changes.

Fixed-Scope Project

Defined requirements, fixed price and timeline. Best for a clear, well-scoped product or feature set.

Best for: MVPs, marketing sites, single features

Dedicated Team

A designer, developers, and a QA engineer working solely on your product, managed by you or by us.

Best for: Long-term products, ongoing roadmaps

Staff Augmentation

Plug in individual developers, designers, or QA engineers into your existing team on demand.

Best for: Scaling an in-house team, filling skill gaps
