I need a seasoned AWS developer to architect and build an end-to-end, cloud-native accounting and tax application. The core of the system must cover invoicing, expense tracking, and a full tax-filing module, all delivered as a secure, multi-tenant SaaS running entirely on AWS. Key functionality • Real-time double-entry ledger supporting multi-currency books • Automated invoicing with payment gateway hooks (Stripe, PayPal, etc.) • Expense capture (manual and OCR upload) that flows straight into the ledger • Full tax engine able to calculate, file, and archive returns for multiple jurisdictions • On-demand reports: Profit & Loss, Balance Sheet, Cash Flow, plus fully customizable layouts • Direct bank feeds: pull transactions via secure bank APIs and reconcile automatically • Tight payroll integration so salary journals post without manual touch AWS architecture expectations A serverless first approach (Lambda, API Gateway, DynamoDB or Aurora Serverless, S3, Cognito, EventBridge) is preferred for scalability and cost control, but I’m open to your recommendation if you can justify an alternative. CI/CD through CodePipeline or GitHub Actions should deliver zero-downtime deployments, and infrastructure must be reproducible with CloudFormation or Terraform. Deliverables 1. Solution architecture diagram and tech stack decision document 2. Fully deployed MVP in my AWS account, reachable through a React or Angular SPA 3. Source code in a private Git repo with clear commit history and README setup instructions 4. API documentation (OpenAPI/Swagger) plus sample Postman collection 5. Unit and integration test suite hitting at least 80 % coverage 6. Knowledge-transfer walkthrough and handover of all credentials Acceptance criteria • Successful creation of invoices, expenses, and tax filings without errors • Accurate generation of P&L, Balance Sheet, and Cash Flow reports using live data • Bank feed connects to at least one sandbox institution and imports transactions • End-to-end test passes for a payroll run posting to the ledger • System withstands a load test of 1 000 concurrent users with response <300 ms p95 Timeline and milestone suggestions are welcome; I’m ready to start as soon as we agree on the architecture.

I’ve built cloud-native financial apps with multi-tenant setups on AWS, including real-time ledgers and tax calculations. A serverless architecture using Lambda, API Gateway, and DynamoDB, paired with Cognito for auth, fits well here for scaling and cost efficiency. To keep deployments smooth, I’d suggest GitHub Actions for CI/CD and Terraform to define infrastructure so you get a clean, repeatable setup. For multi-currency ledgers and tax modules, how many jurisdictions and currencies do you anticipate at launch? That’ll help scope the tax engine and database design. Also, for bank feeds, are sandbox APIs ready from your chosen banks, or should we plan on integrating standard open banking APIs? I can include OCR for expense capture using AWS Textract or a similar tool to auto-post into the ledger. I’ll deliver a clear architecture diagram and stack decision doc upfront and target 80%+ coverage in testing. We can set milestones around core modules (invoicing, ledger, tax filing) so you see progress quickly. Ready to map out the architecture and get your MVP running on AWS promptly.

Hi there, As a senior AWS cloud architect and DevOps engineer, I can design and deliver a fully cloud-native, multi-tenant accounting and tax SaaS on AWS with a secure, scalable, serverless-first architecture. My approach would center on API Gateway + Lambda microservices, Aurora Serverless (for transactional double-entry integrity) or DynamoDB where appropriate, Cognito for tenant isolation, EventBridge for domain events, S3 for document/OCR storage, and Step Functions for tax and payroll workflows—fully provisioned via Terraform for reproducibility. I’ve built financial-grade systems before, including ledger-based platforms with multi-currency support, payment gateway integrations (Stripe/PayPal), and bank-feed ingestion via secure APIs with reconciliation engines. CI/CD through GitHub Actions or CodePipeline will ensure zero-downtime deployments, with automated testing targeting 80%+ coverage and load-tested to meet your 1,000 concurrent users <300ms p95 requirement. I will deliver a complete architecture pack, deployed MVP in your AWS account, documented APIs (OpenAPI), test suites, and structured knowledge transfer. I’m ready to start immediately and can propose a phased milestone plan beginning with architecture validation and ledger engine implementation. Best Regards Laiba

Hi, I can architect and build your cloud-native accounting and tax SaaS on AWS, delivering a secure, scalable, and serverless-first solution with multi-tenant support. The main challenge is combining real-time double-entry ledger, automated invoicing, tax filing, and bank feeds while ensuring high performance and cost efficiency. I’ll design the system using Lambda, API Gateway, DynamoDB/Aurora Serverless, S3, Cognito, and EventBridge, with CI/CD pipelines via CodePipeline or GitHub Actions for zero-downtime deployments. React or Angular SPA will provide a fast, responsive frontend, and all APIs will be fully documented with OpenAPI/Swagger. Your MVP will include invoices, expenses (manual + OCR), tax filings, reports (P&L, Balance Sheet, Cash Flow), bank feed integration, and payroll automation. The codebase will be version-controlled, unit-tested (80%+ coverage), and production-ready, with CloudFormation/Terraform templates and a full knowledge-transfer session. I have experience building financial and SaaS applications on AWS, ensuring security, multi-tenancy, and high performance under concurrent load. The architecture and deployment will be designed for future expansion with minimal rework. Thanks,
