Custom Software Development

Software development — APIs, microservices & web apps.

Need it built, not just unblocked? We design and develop production-grade software end-to-end — robust Java/Spring Boot backends, clean REST APIs, modern frontends, and cloud deployment — backed by 9.5+ years shipping reliability-critical systems in banking and enterprise.

What we build

From a single API to a full application.

Backend is our home turf — but we deliver the whole stack, designed for scale and stability from day one. Don't see your exact technology? Just ask — we work across most JVM, web and cloud tools.

Backend & microservices — Java and Spring Boot services designed with proper HLD/LLD.
REST & SOAP APIs — well-documented (Swagger) contracts and integrations.
Web applications — Angular or React frontends wired to your backend.
Databases — schema design and query optimisation on PostgreSQL, MySQL or Oracle.
Async & messaging — Kafka / RabbitMQ pipelines for high-volume processing.
Caching & performance — Redis and in-memory strategies for fast response times.
Cloud & deployment — AWS, Docker and Jenkins CI/CD pipelines.
Testing & reliability — JUnit/Mockito coverage and production-grade error handling.

Proof of work

Systems already shipped to production.

The same engineering that's gone into high-volume banking and enterprise software.

Financial systems

Risk & Limit Processing Platform

Scalable microservices for financial exposure and limit calculations — full HLD/LLD, core risk logic, external integrations, and SQL/caching optimisation improving performance by ~30%.

API security

Metric Gateway — API Security Platform

A secure API gateway for controlled access to financial data: request flow, validation, authorization, and high-volume microservices with caching.

Distributed systems

Issue Tracker + Distributed Tracing

Microservices and Angular UI with Jaeger distributed tracing for monitoring, dependency tracking and root-cause analysis across services.

Enterprise & BFSI

Transaction Monitoring & E-commerce APIs

REST/SOAP services for transaction monitoring, plus backend APIs for product/sponsored-content monetisation and role-based asset workflows.

How we work

Clear scope, steady delivery.

Scope

We define what you need, the architecture, and a fixed, agreed price.

Design

HLD/LLD, API contracts and data models before a line of code.

Build

Iterative development with regular check-ins, tests and reviews.

Deploy

Shipped to your cloud with CI/CD, docs and handover.

Software development FAQ

Common questions.

Do you build full applications or just backends?+

Both. Our deepest strength is backend and microservices in Java/Spring Boot, and we also build the frontend (Angular or React) and handle databases, cloud and deployment to deliver complete applications.

How is a project priced?+

Per task or per project with a fixed, agreed scope and price up front — decided after a free call where we understand your requirements. No surprises mid-build.

Can you work with our existing codebase?+

Yes. We can extend, refactor or stabilise existing Java/Spring Boot systems, optimise queries and performance, and add new services or APIs to what you already run.

Will the code be maintainable after handover?+

That's the point. We follow modular design patterns, document APIs with Swagger, add JUnit/Mockito tests, and hand over clean, readable code your team can own.
