Legacy Optimization

Modernize Legacy Systems Without Risky Rewrites

Q: How much code change is actually required?

Typically less than 1% of your codebase needs modification. AADC integrates at the type level, so most of your existing logic remains unchanged. The main changes involve replacing numeric types and adding recording boundaries.

Q: Will AADC work with our 15-year-old C++ codebase?

Yes, AADC supports C++11 through C++20 and works with older codebases. It's designed to integrate with real-world production code, not just clean greenfield projects. Our integration team has experience with legacy systems across major banks.

Q: How does this help with FRTB and SA-CCR compliance?

FRTB and SA-CCR require extensive sensitivity calculations that are computationally expensive. AADC's automatic AAD provides these sensitivities at near-zero marginal cost, making previously infeasible regulatory calculations practical within existing time windows.

Q: What if our rewrite projects keep failing?

This is exactly the scenario AADC was designed for. Instead of attempting high-risk rewrites that often fail, AADC accelerates your existing working code. You preserve all business logic while achieving the performance gains you need—without the multi-year timeline and failure risk of a complete rewrite.

Q: How quickly can we see results?

Initial proof-of-concept integration typically takes 2-4 weeks. Full production deployment follows in 2-4 months. This is dramatically faster than rewrite approaches which often take 2-5 years—and frequently fail to deliver.

Achieve 6-100x speedup with less than 1% code changes. Preserve the institutional knowledge embedded in your codebase while delivering modern performance.

Your Code, Accelerated

Legacy analytics code often represents years of accumulated business logic and institutional knowledge. AADC lets you preserve that investment while dramatically improving performance. No risky rewrites, no extended project timelines—just integration and acceleration.

Typical Problems

Common challenges with legacy quant systems

Unresolved legacy bugs that nobody dares to fix?

Never-ending refactoring that never quite finishes?

Intraday risk calculations too slow for trading?

Overnight batches running into the trading day?

Inaccurate hedging due to missing Greeks?

Risk reports not granular enough for regulators?

Code becoming unreadable over time?

Original developers have left the organization?

Modernization projects that never deliver?

The AADC Solution

AADC takes a fundamentally different approach to legacy modernization. Instead of rewriting your codebase or migrating to new platforms, AADC works with your existing code. Through sophisticated JIT compilation and automatic algorithmic differentiation, AADC accelerates your legacy analytics while preserving every line of battle-tested business logic. The result: 6-100x faster execution and complete Greeks with less than 1% code changes.
