Who do you typically work with?

We work with mid-market and enterprise teams, and growth-stage companies, that need help building software, modernizing platforms, or improving how they deliver technology. Most clients have an internal team and want a partner who integrates quickly and communicates clearly.

How does an engagement usually start?

Most projects begin with a short discovery conversation about your goals, constraints, and current systems. From there we outline scope, approach, and timeline options. If there is a fit, we formalize the work in a statement of scope or proposal before development begins.

How is pricing structured?

Pricing depends on scope, team size, and engagement type. We typically work on fixed-scope projects, monthly retainers for ongoing support, or time-and-materials for early discovery. We share estimates upfront and flag changes before they affect budget or timeline.

How long does a typical project take?

Smaller builds or focused improvements often run a few weeks to a few months. Platform modernization, cloud migration, or multi-team programs can take longer. We set milestones early so you can see progress and adjust priorities as needed.

Can you work alongside our in-house team?

Yes. We regularly embed with internal engineering, product, and IT teams, handling defined workstreams, augmenting capacity, or leading specific initiatives while your team owns the broader roadmap.

The Technical Challenge

Navigating Constraints and Legacy Bottlenecks

The client operated a mission-critical billing and payment pipeline processing hundreds of thousands of daily transactions through an aging monolithic codebase. Database connection exhaustion, cascade failure risks during peak volume, and monolithic deployment locks prevented the engineering team from releasing features safely or scaling transaction volume.

Engineering & Architecture

Disciplined Architecture & Incremental Execution

Spadeworks designed and executed an incremental strangler-pattern migration. We decomposed the payment flow into asynchronous Go microservices communicating over resilient message queues. We added robust idempotency keys, distributed transaction compensation, and an automated zero-downtime canary deployment pipeline on AWS ECS with comprehensive telemetry.
