QREWSOFT — HOW WE ENGINEER SOFTWARE

EVERYTHING YOU NEED. NOTHING YOU DON'T.

Custom web applications, multi-tenant SaaS architecture, AI integration, and dedicated senior engineering teams. Built in 2-week sprints, in your repos, under your full ownership.

> ENGINEERING CAPABILITIES

Full-Stack Custom Development

01

Custom Web & API Engineering

+

High-concurrency web applications, REST & GraphQL APIs, complex database schemas, and microservice architectures built for reliability. We write clean, tested code directly inside your GitHub/GitLab repositories.

React & Next.js Laravel & PHP Java Spring Boot Node.js MySQL & PostgreSQL Docker & Cloud APIs
02

AI & LLM Systems Integration

+

Transform your software with real AI capabilities. We build Retrieval-Augmented Generation (RAG) search across your data, autonomous workflow agents, automated data enrichment pipelines, and custom prompt evals.

03

Multi-Tenant SaaS Architecture

+

Build SaaS platforms engineered to scale. Complete database tenant isolation, automated subscription billing (Stripe & Razorpay), role-based admin controls, and custom matching algorithms.

04

Embedded Senior Developer Team

+

A dedicated squad of senior software engineers joining your sprint cadence. You point us at backlog epics or new features; we build, demo, and merge every two weeks. No long recruitment cycles.

06

Product Audit & Fixed-Price Sprint

+

Start with low risk. A 1-week architecture audit or a 2-week feature sprint. Fixed scope, fixed price, ending with concrete code shipped into production or a prioritized build plan.

1-Week Audit ($1.5k–$3k) 2-Week Sprint ($2.5k–$5k) Fixed Scope & Price
> ENGAGEMENT MODELS

Four ways to work with us.

Start small with a 2-week sprint or audit, then move to an embedded team once you see us ship.

Primary Retainer Model

Embedded Engineering Team

A small senior team joins your sprints and ships web, mobile, or AI features every two weeks. You get the throughput of a senior software team without the 6-month recruitment risk. Weekly demos, your backlog, your priorities.

$4k–$10k / monthOngoing, sprint by sprintNo lock-in — cancel any time
Low-Risk First Step

Feature Engineering Sprint

Two weeks. One major software or AI feature shipped into your product. We scope it with you on day one, build in the open, and merge production-ready code into your branch at the end.

~$2.5k–$5k fixed2 weeksProduction-ready code
Architecture Mapping

Architecture & AI Audit

One week. We inspect your software codebase, data structures, and APIs to map performance upgrades or AI integration opportunities — backed by a prioritized build plan.

~$1.5k–$3k fixed1 weekPrioritized build plan
Pre-Launch Founders

Idea → MVP Build

A complete web or mobile MVP shipped in 8–12 weeks. Designed for funded founders or companies needing a high-impact first release. See founders track

$12k–$40k fixed build8–12 weeks+ $2k–$6k/mo retainer
> SPRINT CADENCE

Two weeks, start to demo.

Day 1

Scope

We agree on the feature target, API endpoints, and acceptance criteria.

Day 2–4

Spike

Data models and core logic proven end-to-end on a thin slice.

Day 5–9

Build

Production code written inside your branch with tests, error handling, and UI integration.

Day 10

Demo & Merge

Live working demo with your team, pull request approved, and merged to your main branch.

> GROUND RULES

Six principles we don't bend.

01

Two-week sprints

Every sprint ends with a working demo. No month-long black boxes.

02

Senior team

Senior software engineers only. Direct contact, zero account managers.

03

100% Code Ownership

Our work lands in your repos and your cloud infrastructure, merged as we go.

04

Weekly Demos

You see software features move every week and can adjust priorities early.

05

Start Small

A sprint or an audit first. Commit to ongoing retainers only after seeing us ship.

06

No Lock-in

Month-to-month contracts. Stop whenever; everything built is already yours.
