Common Questions
Frequently Asked Questions
Common questions about Flexsin's product development services, our product development consulting approach, what makes us a leading product development company, and how to start building your product with us.
-

Flexsin has delivered 2,500+ software products across 30+ industries over 18 years - making us a trusted product development company for global enterprises, funded startups, and growth-stage businesses alike. Our differentiators: a single team owning the full lifecycle (strategy through managed support), 500+ engineers across every major tech stack, 91%+ test coverage standards, and transparent agile delivery with real-time project dashboards.
-
What product development services does Flexsin offer?
Flexsin offers full-cycle product development services including product strategy and architecture, custom software product development, cloud-native application development, application modernisation, product migration, QA and testing, API development, DevOps and CI/CD engineering, and managed post-launch support and maintenance.
-
What does Flexsin's Product Development Consulting service include?
Our product development consulting service covers product discovery workshops, competitive market analysis, MVP scope definition, technical architecture blueprint, technology stack selection, cloud infrastructure strategy, build-vs-buy analysis, and a detailed go-to-market roadmap. Our product development consultants ensure you invest in the right architecture before a single sprint begins - eliminating costly structural rework mid-project.
-
How do you approach product architecture before development begins?
We run a structured discovery and architecture phase - requirements workshops, competitive analysis, MVP scope definition, and a detailed technical architecture blueprint covering system design, database schema, API contracts, infrastructure design, and technology stack selection. Architecture decisions are documented and peer-reviewed before sprint 1 begins, eliminating costly structural changes mid-build.
-
What is your approach to agile product development?
We follow two-week sprints with daily standups, bi-weekly sprint demos with working software (not slide decks), sprint retrospectives, and a real-time project dashboard giving stakeholders visibility into velocity, burn-down, and upcoming deliverables. Every sprint ships tested, deployable increments - no big-bang releases.
-
Can you build and deploy cloud-native products on AWS, Azure, or GCP?
Yes. We build cloud-native products on all three major cloud providers - containerised with Docker and Kubernetes, serverless where appropriate, with Infrastructure-as-Code using Terraform, automated CI/CD pipelines, monitoring with Prometheus and Grafana, and blue/green deployment strategies for zero-downtime production releases.
-
What tech stacks do your product teams use?
Our teams work across React, Next.js, Angular, Vue, Node.js, NestJS, Python (FastAPI/Django), Java Spring Boot, .NET Core, PostgreSQL, MongoDB, Redis, Elasticsearch, Kafka, AWS, Azure, and GCP. We match the stack to your product requirements rather than prescribing a single technology choice.
-
How do you handle QA and testing for product releases?
QA is integrated throughout the development cycle - unit and integration tests written alongside code, automated e2e tests with Cypress or Playwright, API contract testing, load and performance testing with k6 before launch, OWASP ZAP security scanning on every build, and moderated UAT sessions with real users before every production release.
-
Do you build SaaS products and multi-tenant architectures?
Yes. We design and build multi-tenant SaaS architectures - tenant isolation strategies (database-per-tenant, schema-per-tenant, row-level-security), subscription and billing integration (Stripe), usage metering, tenant administration portals, and elastic cloud infrastructure that scales cost-efficiently with your customer base.
-
How does your CI/CD pipeline setup work?
We configure end-to-end CI/CD pipelines using GitHub Actions, GitLab CI, or Jenkins - automated build, unit test, integration test, security scan, Docker image build, and deployment to staging on every pull request. Production deployments use blue/green or canary strategies with automated health checks and rollback triggers.
-
What engagement models do you offer for product development?
We offer Fixed-Price (defined scope, milestone billing), Dedicated Product Teams (embedded cross-functional team on monthly engagement), Agile T&M Sprints (backlog-driven, flexible scope), and Managed Support Retainers (SLA-backed post-launch maintenance and feature development). We recommend the right model after a scoping conversation.
-
How do you protect our IP and code ownership?
All client IP is fully assigned at the point of payment - you own everything from day one. We sign comprehensive NDAs before any technical discussion. Code lives in your private repository (or transferred on completion), and access is restricted to engineers directly assigned to your project, with revocation on engineer offboarding.
-
Can you integrate our product with third-party systems?
Yes. We design and build third-party integrations as a core part of every product build - payment gateways (Stripe, PayPal, Braintree), CRM systems (Salesforce, HubSpot), ERPs (SAP, Dynamics), identity providers (Auth0, Okta), communication APIs (Twilio, SendGrid), and any system with a REST or GraphQL API.
-
