Architectural Advisory for Financial Services Platform

Architectural Advisory for Financial Services Platform

Sathik has been a trusted technology partner for our client — a financial services organization with complex systems and evolving needs. Most recently, he was brought in for code review and architecture advisory on a critical backend refactor aimed at improving security, performance, and scalability.

Long-Term Partnership

Working with Arivelm Technologies for nearly 10 years, the client has consistently relied on Sathik’s:

  • Deep technical knowledge across multiple stacks

  • Calm, methodical approach to system design

  • Transparent and business-aligned communication

This level of trust led to his involvement in strategic, high-impact work beyond typical development — including architectural overhauls and security assessments.

Problem

The client’s financial platform was:

  • Experiencing performance bottlenecks under load

  • Carrying legacy code with security vulnerabilities

  • Inconsistent in enforcing data validation and architectural best practices

They needed an experienced architect to perform a deep-dive review and provide an actionable improvement roadmap.

Solution by Arivelm (Sathik)

Sathik performed a multi-phase audit and guided the team through:

  • Full backend architecture review (ASP.NET Core, SQL Server, Azure)

  • Refactoring recommendations for service decomposition and modularity

  • Database indexing, schema optimization, and query profiling

  • Enhanced JWT authentication flow and encryption of sensitive data

  • CI/CD pipeline improvements with better test coverage and rollback plans

Technologies Involved

  • ASP.NET Core

  • SQL Server

  • Azure

  • JWT Auth, bcrypt, and HTTPS TLS config

  • GitHub Actions / Jenkins for CI/CD

Impact of Architectural Advisory for Financial Services Platform

  • Modular Architecture:
    Processes were split into independently managed services, enabling isolated startups, fault containment, and targeted deployment per module.

  • Improved User Experience:
    Separation of concerns led to smoother UX by reducing inter-module bottlenecks and allowing focused optimization.

  • Fault Isolation:
    Failures in one component no longer affected the entire system, significantly improving reliability and maintainability.

  • Horizontal Scalability:
    Modules can now scale independently based on load, reducing infrastructure cost and increasing responsiveness.

  • Cache Optimization:
    Implemented intelligent caching layers to avoid repetitive database hits, leading to faster data access and reduced DB load.
