We don't integrate with legacy.We replace the logic.
Your stack isn't the problem. The architecture is. Mercury engineers embed in your team and rebuild the operating logic — API-first, microservices-native, AI-ready.
API-First, Microservices-Native
Not a monolith with APIs bolted on. Designed as composable services from day one.
Forward-Deployed Engineering
Senior engineers in your standups, your Slack, your repos. Not consultants with slide decks.
Immersion
- → Join your daily standups
- → Read your codebase, not your docs
- → Map the shadow infrastructure
Prototype
- → Ship to staging daily
- → Production deploys weekly
- → Pair program with your team
Handoff
- → Productionize and harden
- → Knowledge transfer sessions
- → Architecture decision records
Hong Kong Listed Conglomerate
Multi-billion dollar group with 14-day approval workflows and cross-border reconciliation nightmares. Legacy ERP held together with scripts and manual processes.
We didn't integrate. We rebuilt.
Questions CTOs Ask
What tech stack does Mercury use?
We build on modern, proven technologies: Next.js, Node.js, PostgreSQL, MongoDB, Redis, and Docker. For AI, we use LangChain, OpenAI, and custom model deployments. We match our stack to your infrastructure requirements and compliance needs.
How do you handle knowledge transfer?
Knowledge transfer is built into our methodology, not bolted on at the end. We pair program with your team daily, document architecture decisions in ADRs, and run formal handoff sessions in the final weeks. Your team owns the system.
Can you work with our existing cloud provider?
Yes. We deploy to AWS, GCP, Azure, or on-premise infrastructure. We also support multi-cloud and hybrid configurations. Our architecture is cloud-agnostic by design.
What about security and compliance?
Security is embedded, not added later. We follow SOC 2 principles, implement zero-trust architecture, and can adapt to industry-specific compliance requirements (HIPAA, PCI-DSS, GDPR, etc.).
How do you price engineering engagements?
We price based on team composition and duration, not hourly rates. A typical forward-deployed team is 2-3 engineers for 12 weeks. We offer fixed-price options for well-defined scopes and retainer models for ongoing work.

Ready to Rebuild the Logic?
If your architecture has been patched past the point of recognition, we have engineers who can rethink it.
