We are seeking an experienced Technical Solution Architect to document two fully developed and operational technology platforms. The platforms have already been designed and built. This engagement is focused entirely on reviewing the existing systems and producing complete, professional, enterprise-grade technical documentation. Scope of work: * Review the existing source code, repositories, infrastructure, databases, APIs and third-party integrations. * Conduct technical discovery sessions with our development and management teams. * Document the complete current-state solution architecture. * Create high-level and low-level architecture documents. * Produce professional architecture diagrams, including: * System context diagrams * Solution architecture diagrams * Application and component diagrams * Infrastructure and cloud architecture diagrams * Network and security architecture diagrams * Data-flow diagrams * Database and entity-relationship diagrams * API and third-party integration diagrams * User authentication and authorization flows * Deployment and CI/CD workflows * Backup, disaster-recovery and business-continuity flows * Document the frontend, backend, databases, services, APIs and technology stack. * Document data processing, storage, encryption, access controls and retention. * Prepare API and integration documentation. * Document user roles, permissions and administrative functions. * Prepare deployment, configuration, maintenance and troubleshooting guides. * Document security controls, logging, monitoring and incident-management processes. * Identify any documentation gaps, technical risks or inconsistencies discovered during the review. * Deliver editable source files for all documents and diagrams. Required experience: * Proven experience documenting complex SaaS, FinTech, RegTech or enterprise platforms. * Strong background in solution architecture, software architecture and cloud infrastructure. * Ability to understand an existing system by reviewing code, repositories and infrastructure. * Experience producing professional documentation suitable for developers, auditors, regulators, investors and enterprise clients. * Strong experience with tools such as Microsoft Visio, Lucidchart, [login to view URL], Mermaid or equivalent. * Excellent technical writing and English communication skills. * Strong understanding of APIs, databases, cloud environments, cybersecurity and DevOps. Expected deliverables: * Complete Technical Architecture Document * High-Level Design document * Low-Level Design document * Software and infrastructure inventory * API and integration documentation * Database and data-flow documentation * Security architecture documentation * Deployment and operational guides * Complete set of editable architecture diagrams * Documentation gap and technical-risk report * Final knowledge-transfer and handover session This is not a software-development engagement. Both platforms are already built. We require a senior professional who can understand the existing systems and convert them into complete, accurate and professionally structured technical documentation. Applicants must provide relevant samples of previous architecture documentation and diagrams. An NDA will be required before access is granted to the platforms, repositories or infrastructure.

Hi, I will review both platforms end to end, run discovery sessions with your developers and managers, and deliver enterprise grade technical architecture and operational documentation covering high level and low level design, editable diagrams, API and integration specs, deployment and CI/CD workflows, security and incident processes, database and data flow diagrams, and the gap and risk report you described. I previously produced complete architecture and operational documentation for two enterprise SaaS platforms, a payments gateway and a KYC workflow engine, including Lucidchart source files and OpenAPI specs. Deliverables will include editable source files and a final knowledge transfer session. If you sign the NDA and grant repo access I will provide a written list of documentation gaps plus a proposed table of contents for each platform within 48 hours, free and no commitment. Ali Zain

Hi, Your project is about turning two already-built platforms into clear, enterprise-grade documentation. That means reviewing the current codebase, infrastructure, APIs, data flows, and integrations, then translating the whole system into accurate architecture and operational documents. I’ve worked on technical documentation for complex platforms where the source of truth had to be reconstructed from repositories, cloud resources, and team discovery sessions. I’m comfortable documenting SaaS-style systems, APIs, databases, security controls, deployment flows, and CI/CD processes. My approach is to first map the current state end to end, then validate findings with your technical and management teams, and finally produce structured HLD/LLD documents, diagrams, and handover-ready guides. I focus on clarity, consistency, and traceability so the documentation is useful for engineers, auditors, and stakeholders alike. I’d be glad to discuss the scope and documentation standards with you. Best regards, Gabriel

Hello, your project requires more than writing documents; it requires understanding complex systems and converting existing technology into a reliable knowledge base. I can assist in reviewing your operational platforms and creating professional architecture documentation suitable for enterprise use. I think you want to preserve the knowledge behind your systems, reduce dependency on individual developers, and have clear visibility of how applications, databases, APIs, infrastructure, and security controls work together. I can create complete technical documentation with architecture diagrams, component views, deployment workflows, database models, integration maps, and operational procedures. My workflow will start with technical discovery sessions, system analysis, and repository/infrastructure review. Then I will prepare structured documents, identify gaps or risks, and provide final editable materials with handover support. Could you share the current platform stack, available documentation, repository access method, and any compliance or audit requirements? Looking forward to work with you. Thanks
