Backend Development Services

The Engine Behind
Every Great Product.

Your frontend is what users see. Your backend is what determines whether it works under pressure. Gensoft architects and builds server-side systems — APIs, databases, integrations, and business logic — designed for the scale your product will grow into.

What We Build

Backend Development Services

From designing a database schema to architecting a distributed microservices system — we handle the full range of server-side engineering challenges.

Backend Architecture Design

We design scalable, fault-tolerant architectures — monolith, microservices, or event-driven — that match your current team size and grow gracefully as load increases. Business-first, not over-engineered.

Custom Backend Development

Business logic, authentication systems, multi-tenant data isolation, background job processing, scheduled tasks, and workflow engines — built clean, tested thoroughly, and documented for your team.

API Development & Integration

RESTful and GraphQL APIs built to OpenAPI specs, plus robust integrations with third-party platforms — payment gateways, CRMs, ERPs, communication tools, and cloud services.

Database Design & Optimisation

Schema design, indexing strategy, query optimisation, replication, and sharding for SQL and NoSQL databases. We design for performance from the start — not after you hit your first slow query crisis.

Microservices & Event-Driven Systems

Decompose monoliths into independent, deployable services. We design service boundaries, implement message queues and event streams, and build the orchestration layer that keeps distributed systems reliable.

Performance & Scalability Engineering

Load testing, bottleneck diagnosis, caching strategies, connection pool tuning, CDN configuration, and horizontal scaling — turning a backend that handles 100 users into one that handles 100,000.

How We Work

Our Backend Development Process

Architecture-first. Test-driven. Documented. Delivered in sprints you can see progress in from week one.

01
Requirements & Discovery

We map your business logic, data flows, performance requirements, and integration points — building a shared functional spec before any architecture is decided.

02
Architecture Design

We produce a written architecture document — system diagram, data model, API contracts, service boundaries, and technology decisions with rationale — reviewed and approved before development begins.

03
Sprint-Based Development

Two-week sprints with daily standups, mid-sprint check-ins, and a demo at the end of every cycle. Each sprint delivers working, tested functionality — not just progress reports.

04
Code Review & Quality Gates

Every PR is reviewed by a senior engineer. Automated checks enforce code style, test coverage thresholds, and security scanning before any code merges to the main branch.

05
Deployment & Monitoring

CI/CD pipelines deploy automatically to staging for every merged PR. Production deployments use blue-green or canary strategies with rollback capability and observability from day one.

06
Handoff & Knowledge Transfer

Comprehensive README, ADRs (architecture decision records), runbooks, and a live walkthrough with your team. Your engineers inherit code they understand, not a black box.

FAQ

Backend Development FAQs

Common questions from CTOs and engineering managers starting a backend project.

Talk to a Backend Engineer

The honest answer: start with a monolith unless you have a specific reason not to. Microservices add significant operational complexity — distributed tracing, service discovery, network latency, independent deployments — that slows small teams down considerably. We recommend microservices when you have multiple teams working independently, well-defined service boundaries, and the DevOps maturity to operate them. We'll recommend the right architecture for your stage of growth.

Technical debt is inevitable — what matters is managing it intentionally. We enforce it through: mandatory code reviews by senior engineers, test coverage thresholds in CI, automated linting and static analysis, architecture decision records for every major choice, and a dedicated "debt sprint" every quarter to address accumulated shortcuts before they compound. We also flag scope changes that would introduce significant debt and give you the trade-off clearly before proceeding.

We use versioned, reversible migration scripts (Flyway, Liquibase, EF Core Migrations) committed alongside the code that needs them. For large tables or breaking schema changes, we use expand-contract patterns — adding new columns or tables while keeping old ones live, migrating data in background jobs, then removing the old schema in a later release. This eliminates the need for planned downtime for schema changes in most cases.

Yes — we do this regularly. We begin with a codebase audit to understand the architecture, identify the highest-risk areas, and map out how our work will integrate with what exists. We adopt your code style and conventions, integrate into your CI/CD pipeline, and add to your test coverage rather than working around it. Our goal is to leave the codebase better than we found it.

We design for the reliability level your business actually needs — not the maximum possible (which is expensive) or the minimum (which becomes a liability). This involves defining RTO/RPO targets, designing multi-availability-zone deployments, implementing automated database backups with tested restore procedures, building circuit breakers for third-party dependency failures, and load testing the failover path — not just the happy path.
