Hi I can review and redesign your mortgage FinTech backend database structure so the system has clean relationships, reduced duplication, and a clear source of truth across borrowers, applications, products, lenders, documents, and pipeline modules. The main technical problem is that disconnected modules and repeated data can create inconsistent records, reporting issues, migration risk, and confusion for developers working on future features. I have experience with PostgreSQL, MySQL, normalized schema design, ERD creation, SaaS data models, FinTech-style workflows, indexing strategy, migration planning, and developer-ready architecture documentation. My approach would be to audit the current tables, relationships, duplicate fields, ownership rules, constraints, and data flow before proposing a cleaner target schema. I can define entity ownership, module boundaries, relationship maps, primary/foreign key structure, indexing recommendations, and migration rules for existing and expanded product data. The final documentation can include an audit report, new schema, ERD, system flow, migration plan, and implementation guide your developers can follow without needing production access. I will keep the work focused strictly on database architecture and backend structure, not frontend or feature implementation. Thanks, Hercules

Hi there. Your FinTech mortgage platform needs a full database cleanup, and the pain points you listed are familiar territory. I’ve redesigned complex SaaS and finance schemas before, so I understand the mess duplicated tables and unclear ownership can create. I’d focus on a clear, simple plan: - audit all modules and map real data flows - mark duplication and fix relationship gaps - design a normalized schema with clear ownership - draft an ERD and module interaction map - propose safe migration steps and indexing notes I can start right away and can finish the design work within a few days. Before I begin, can you confirm whether each module currently has its own data store or if everything lives in a single shared database? Cheers, Slavko

Hello, I hope you are well. I’m a seasoned database architect focused on clean, scalable SaaS backends for FinTech. I’ve designed and normalized complex schemas, improved data integrity, and established single sources of truth for multi‑module platforms that include borrowers, applications, products, lenders, and documents. In past projects I audited PostgreSQL/MySQL structures, eliminated duplicated data, redefined relationships, created comprehensive ERDs, migration plans, and developer guides to ensure smooth handoffs. I’ll apply the same approach here: a thorough audit, a normalized schema, clear ownership rules, an actionable ERD, module relationship maps, a migration strategy including product data expansion, and performance/indexing recommendations. I’ll deliver developer‑ready documentation and guidelines, with no frontend work. I can take this on within your fixed scope and deliver a complete system design package. Best regards, Billy Bryan

Hello, As a result of a detailed review of your project requirements, I understand you need a database architect to audit and redesign the backend structure for a mortgage/FinTech platform, focusing on normalization, source of truth, module relationships, and migration planning. I have experience handling similar SaaS database redesign and system architecture projects, and I’m available to start your project right now. I bring strong expertise in MySQL, PostgreSQL, database design, ERD creation, data modeling, SaaS architecture, FinTech workflows, indexing, and data migration planning. For this project, I would review the current schema, identify duplicated data and broken relationships, define ownership for core entities like borrowers, applications, lenders, products, documents, and pipeline records, then design a clean normalized schema with clear module boundaries. I’ll also prepare an ERD, relationship map, migration strategy, indexing recommendations, and developer-ready implementation guide. One key focus is creating a reliable source of truth so future development stays consistent and scalable. I have a couple of quick questions. • Is the current database MySQL or PostgreSQL? • Can you share a schema dump or table structure export for review? Best regards, Carlos
