Examples from our projects

REST API Endpoint

JavaScript / Node.js
async getUserById(id) {
  const user = await db.users
    .findOne({ where: { id } });
  if (!user) {
    throw new NotFoundError();
  }
  return user;
}

Database Query

Python / SQLAlchemy
def get_orders(customer_id):
    return session.query(Order)
        .filter(Order.customer_id == customer_id)
        .filter(Order.status == 'active')
        .order_by(Order.created_at.desc())
        .all()

Unit Test

Java / JUnit
@Test
void testCalculateTotal() {
    Cart cart = new Cart();
    cart.addItem(100.00);
    assertEquals(100.00, 
                  cart.getTotal());
}

API Integration

C# / .NET
public async Task<User> 
FetchUserAsync(string id) {
    var response = await httpClient
        .GetAsync($"users/{id}");
    return await response
        .Content.ReadAsAsync<User>();
}
Frequently asked questions
Which stack do you recommend for a new web app?
Typically React + Node.js or .NET for backend, Postgres for data, and Terraform for IaC. We tailor based on performance, team skillset, and hosting preferences.
Can you migrate an existing monolith to microservices?
Yes. We start with domain decomposition and strangler patterns, add observability, and migrate iteratively with CI/CD and robust testing.
How do you ensure performance and scalability?
We apply caching, async processing, appropriate data models, capacity planning, load testing, and autoscaling policies with SLOs.
What about security and compliance?
Security by default: IAM, least privilege, encryption in transit/at rest, audit trails, secret management, and compliance checks (e.g., ISO/GDPR as needed).
Do you provide documentation and handover?
Yes. We deliver architecture docs, runbooks, onboarding guides, and CI/CD pipelines with environment parity for smooth handover.
Can you maintain and support the solution after go‑live?
We offer SLAs with monitoring, incident response, and continuous improvement, including performance and cost optimization.
