Book a strategy call at prosabbir.com/contact. You receive a written scope, timeline and investment range before any work begins.

Yes. An NDA can be signed before the discovery call, and client code and data stay confidential under the project agreement.

The client owns the source code, design files and infrastructure accounts in full once invoices for the milestone are settled.

Yes. The team can extend an in-house team, take a defined module, or run the whole delivery, using the client's repositories and workflow.

Yes. SaaS builds include multi-tenant data models, subscription billing with Stripe or Paddle, role-based access, admin tooling and usage analytics.

Yes. Cross-platform apps with React Native or Flutter, and native modules where required, released to both the App Store and Google Play.

Yes. AI automation work covers document processing, support agents, RAG-based internal assistants, lead qualification, content pipelines and AI features inside existing products.

Yes. Two-sided marketplaces with listings, search, messaging, reviews, escrow or split payments, and separate buyer, seller and admin experiences.

Yes. A typical MVP covers one core user journey end to end and ships in 4 to 10 weeks so the idea can be tested with real users.

Yes. n8n workflows are built, self-hosted or cloud, to connect CRMs, inboxes, databases, payment systems and AI models without manual data entry.

Yes. Custom CRMs are built when off-the-shelf tools do not fit the sales process, including pipelines, automations, reporting and integrations with existing systems.

Yes. Design is delivered in Figma: user flows, wireframes, high-fidelity screens and a reusable component system that maps directly to the code.

Yes. Common integrations include Stripe, PayPal, Twilio, SendGrid, HubSpot, Salesforce, Shopify, QuickBooks, Google Workspace and OpenAI.

Yes. Developers, designers and QA engineers can be engaged monthly, full-time or part-time, reporting into the client's process.

Yes. Manual back-office work such as onboarding, invoicing, reporting, data entry and approvals is mapped and replaced with automated workflows.

Yes. Existing codebases are audited for architecture, security and performance, then stabilised or rebuilt module by module.

Yes, both custom storefronts and Shopify-based builds, with payments, inventory, shipping and analytics connected.

Yes. Admin panels, operations dashboards and reporting tools are a frequent first project because they replace spreadsheets quickly.

A focused MVP takes 4 to 10 weeks. A full production web or mobile application typically takes 3 to 6 months depending on integrations and compliance requirements.

Define one core user journey, cut every feature that does not serve it, design the screens for that journey, build it with a stack you can extend, launch to a small group of real users and decide the next build from their behaviour.

Discovery call, written scope and quote, UI/UX design, two-week development sprints with preview links, QA and launch, then ongoing support.

A working preview link at the end of every two-week sprint, plus a short written update and a call if decisions are needed.

The problem you are solving, who the users are, any existing designs or systems, your deadline and your budget range.

Yes. Store listings, assets, privacy declarations, review responses and release management are part of a mobile engagement.

Monitoring, bug fixes and an agreed monthly capacity for improvements, with analytics reviewed to decide what gets built next.

Code review on every change, automated tests on critical paths, manual QA against the agreed scope, and performance and security checks before release.

A small internal tool or automation typically costs $3,000 to $10,000. An MVP usually falls between $8,000 and $30,000. A full production platform generally starts at $30,000 and scales with integrations, compliance and team size.

A cross-platform app with authentication, core features and payments usually costs $12,000 to $40,000, depending on the number of screens and integrations.

Fixed price per milestone for defined scopes, and monthly retainers for dedicated developers or ongoing product work.

Payments are tied to milestones, usually an upfront deposit and then a payment on each completed milestone.

Yes: hosting, third-party APIs and app store fees are billed directly to your accounts, and optional support retainers cover maintenance.

Yes. The first 30 minute call and the written scope summary that follows are free.

React, Next.js and TypeScript on the front end; Node.js, NestJS, Python and Laravel on the back end; PostgreSQL, MySQL, MongoDB and Redis for data; React Native and Flutter for mobile; AWS, Google Cloud, Vercel and Docker for infrastructure; OpenAI, Claude, Gemini, LangChain and n8n for AI and automation.

Zapier is faster for simple, low-volume connections between popular SaaS apps and is priced per task. n8n is self-hostable, handles branching logic, code steps and high volumes at a flat infrastructure cost, and keeps data inside your own environment. Choose Zapier for quick wins, n8n for complex or high-volume workflows and data control.

Use SaaS when your process is standard and the subscription is cheaper than building. Build custom software when the process is your competitive advantage, when you are paying for many overlapping tools, or when you need data and workflows the SaaS cannot express.

n8n or Make for workflow orchestration, OpenAI or Anthropic Claude models for reasoning and text, a vector database such as pgvector or Pinecone for retrieval over your own documents, and a custom application layer when the workflow becomes a product.

Yes. AI search, summarisation, classification, chat assistants and document extraction can be added to an existing codebase without a rebuild.

Least-privilege access, encrypted secrets, row-level authorisation in the database, dependency scanning, and reviews of authentication and payment flows before launch.
