Let's Talk
Backend Engineering That Holds Up in Production
Secure APIs, integrations and data systems built to scale and built to be operated. We design, build and run the backend, accelerate the work with AI, and keep a senior engineer reviewing every change.
APIs & Microservices
Clean contracts. Reliable services.
We design REST and GraphQL APIs and services that are secure, versioned, documented and easy for your teams and partners to build on.
- REST and GraphQL API design
- Microservices and modular monoliths
- Authentication, authorization and rate limiting
- API documentation and SDKs
- Node.js, Python, Go, .NET and Java
Integrations & Interoperability
Connect the systems your business runs on.
From HL7/FHIR in healthcare to payment processors, payers and ERPs, we build integrations that handle real-world data, retries and failures gracefully.
- HL7/FHIR and healthcare data exchange
- Payment processor and banking integrations
- ERP, CRM and legacy system connectors
- Event-driven and queue-based processing
- Monitoring and alerting on every integration
Data, Performance & Reliability
Fast today. Fast at ten times the load.
We tune databases, caching and infrastructure for performance, and build in observability so issues are found before your customers find them.
- SQL and NoSQL data modeling
- Caching and query optimization
- Load testing and capacity planning
- Logging, metrics and tracing
- On-call support and incident response
How We Deliver Backend Engineering, Owned End to End
One accountable team from first conversation to production support. AI accelerates the routine work; senior engineers make every decision that matters and review every change. You own the code, the data and the infrastructure.
- 01
Discovery
A domain expert maps your goals, users, systems and compliance needs, and reviews any existing code or prototype.
- 02
Proof of Concept
We validate the riskiest assumptions with a working prototype on real data, or harden the one your team already built.
- 03
Architecture
We choose a secure, scalable and maintainable design, documented so your team can own it too.
- 04
AI-Accelerated Build
Short sprints with regular demos. AI speeds up coding, tests and documentation; senior engineers review every change.
- 05
Quality & Compliance
Automated and manual testing, security review, and HIPAA, SOC2 or PCI-DSS controls where they apply.
- 06
Launch
Planned, monitored releases with rollback plans, so going live is a non-event.
- 07
Own & Run
We monitor, support, stay on call and keep improving it, or hand it over with full documentation.
Backend Engineering FAQs
Common questions about working with Loku Digital on backend engineering.
Can you work on our existing backend?
Yes. We start with a code and architecture review, then improve, extend or gradually modernize it without disrupting production.
Which languages and frameworks do you use?
Mostly Node.js, Python, Go, .NET and Java, chosen to fit your team and requirements rather than our preferences.
Who owns the code and intellectual property?
You do, from day one. Code, cloud accounts, data and documentation are in your name, and nothing is locked to Loku Digital.
How do you use AI in delivery?
AI handles routine work such as boilerplate code, tests, documentation and code analysis. Senior engineers design the solution and review and test every change before it ships.
Can you work with our existing team or prototype?
Yes. We can harden a prototype your team built, work alongside your engineers, or take full ownership of build and operations, so your team can focus on your core roadmap.
