I'm a senior .NET developer with over 12 years on Upwork, specialising in Windows desktop applications, legacy system work, and business integrations across the Microsoft stack. My background is broad, but where I'm most useful is on the harder projects — undocumented codebases, legacy migrations, ERP integrations, and end-to-end delivery of complex Windows software. These are the kinds of projects I've built a reputation around. A recent example: I designed and built a full Windows Assistant platform using WPF — combining video capture, SharePoint content management with a Windows Explorer-style interface, a locally cached SQLite database with a background sync service, and a Web API built on a clean services/infrastructure architecture over Entity Framework Core and SQL Server. The system included SignalR real-time notifications, JWT authentication, and integrations with Vimeo, Twilio, SmileBack and others, alongside a complete MVC admin portal. What I work on: Legacy systems — VB6, Visual FoxPro, VB.NET, WinForms, WPF. I regularly take on codebases other developers decline, and I'm comfortable working in undocumented or inherited code. ERP and business integrations — SAP, SAGE, MYOB, SQL Server, Oracle, Shopify, DocuSign, Amazon API and more. I've worked across insurance, logistics, and enterprise clients and understand how business-critical systems need to behave. I ask the right questions before I start, flag issues early, and deliver on time. Clients tend to come back for that as much as the technical work. Tech I work with: WPF · WinForms · C# · .NET / ASP.NET · WCF · Entity Framework Core · SQL Server · Oracle · SQLite · SignalR · JWT · REST APIs · SharePoint · MS Office Add-ins · SAP · SAGE · MYOB · VB6 · VB.NET · Visual FoxPro · Shopify · DocuSign · Amazon API · Vimeo · Twilio · MVC

I help research teams and technical founders build and validate reliable, testable scientific and quantitative systems — research prototypes, backtesting frameworks, production execution systems, simulation engines, and performance-critical pipelines. I also conduct independent technical review of quantitative models and research frameworks. Whether you are architecting a new system from the ground up, battling computational bottlenecks, auditing an unpredictable model, or scaling a fragile prototype into production, I can work with you or your team to engineer a robust, high-performance solution. Background: PhD Physics (NYU, 2018). Quantitative Research at JPMorgan Chase — derivatives pricing on a 1M+ LOC C++ library. Max Planck Institute postdoc — general-relativistic hydrodynamics on 1,000+ core HPC clusters. 13 peer-reviewed publications, 1,300+ citations, h-index 12. WHAT I DELIVER ▸ Quant & Options Engineering Backtesting frameworks (event-driven or vectorized), walk-forward, leakage checks Options analytics: Greeks, IV surfaces, Black–Scholes and numerical methods Research → production pipelines (clean architecture, tests, logging, monitoring) Execution integrations (e.g., IBKR) and robust order / risk handling Market data ingestion, cleaning, corporate actions, quality control ML and statistical time-series models with proper cross-validation (no leakage) ▸ Scientific Computing & Research Tooling For physics, chemistry, biology, engineering, and any domain where the core problem is mathematical or computational. Custom numerical solvers (finite volume / finite difference, spectral, particle methods) with stability and convergence analysis Optimization engines (Bayesian, gradient-based, evolutionary) for experimental design, formulation, and parameter search Simulation frameworks from prototype to production grade Scientific data pipelines: ingestion, transformation, quality control, reproducible workflows Verification and validation: benchmarks, unit / regression tests, convergence studies Analysis tools, dashboards, and reporting infrastructure for research workflows Air-gapped and reproducible deployments where IP sensitivity or regulatory context requires it ▸ Quantitative & Mathematical Review (NDA-protected) Independent technical review of quantitative models, frameworks, and research Verification of internal consistency, identifiability, hidden assumptions, and mathematical correctness Assessment of whether the formal structure supports the conclusions drawn from it Implementation review against specification: numerical stability, edge cases, code-to-spec fidelity ▸ HPC & Performance Engineering Distributed computing (MPI / OpenMP / CUDA), GPU optimization, memory and I/O tuning Inference and training infrastructure at scale Profiling, refactors, and speedups for codebases that need to run reliably under production load WHY CLIENTS WORK WITH ME - Trustworthy work — research prototypes turned into tested, reproducible production code; models reviewed against their own claims - De-risking — failure modes surfaced early (leakage, overfitting, edge cases, scaling bottlenecks) - Maintainability — clean architecture, docs, handover-ready delivery your team can extend - Communication — clear milestones, concise updates, realistic timelines, no surprises - Math ↔ engineering bridge — strong intuition for both theory and implementation IDEAL PROJECTS - Quant strategy development, backtesting, and research infrastructure - Options analytics and derivatives tooling - Mathematical review of quantitative manuscripts, white papers, or research frameworks - Independent validation of production models against specification - Market data pipelines and reproducibility upgrades - Performance optimization of slow Python / C++ codebases - Distributed training, GPU optimization, and inference serving for ML workloads - Custom scientific or industrial simulation and numerical software - Internal R&D tooling for research labs and technical teams If this sounds like a fit, message me with a brief on your current setup and success criteria — I'll let you know how I can help.
