You will get a SQL Server performance audit with a prioritized optimization plan
Project details
Senior backend engineer with 15+ years on SQL Server. Recent work: cut a critical API endpoint from 12 seconds at peak to 700ms on a multi tenant platform serving 800K+ users with 100GB+ datasets.
I diagnose SQL Server performance problems from the application layer down to the index layer, so you fix the actual cause rather than the loudest symptom. Output is a written report with prioritized findings, execution plan evidence, and concrete SQL or indexing changes. Higher tiers include implementation in a feature branch, before/after benchmarks, and a walkthrough call.
What I look at: execution plans for your slowest queries, indexing strategy (covering indexes, INCLUDE columns, column ordering), key lookups and tempdb sort spills, parameter sniffing, N+1 patterns from your ORM, statistics health and SARGability, and write impact tradeoffs before any index ships.
What I do not do: reckless NOLOCK suggestions, blanket "add an index" recommendations without measuring write impact, or hand-waving when the data does not back the diagnosis.
NDA-friendly. Comfortable with production-sensitive systems, staged rollouts, and anonymized datasets for debugging and benchmarking.

About Taiwo
Senior .NET/C#, TypeScript Backend Engineer | SQL Server, AWS 15+ Yrs
Vancouver, Canada - 1:56 am local time
Built and scaled platforms serving 800K+ users and payment systems processing 1M+ daily transactions. Cleared SOC 2 Type II and PCI-DSS audits with zero security findings.
Core expertise:
• .NET / C# / SQL Server: ASP.NET Core, EF Core, T-SQL, execution plan tuning, high-scale API architecture
• Node.js / TypeScript / NestJS: PostgreSQL, Redis, SQS, AWS-based distributed systems
• Fintech infrastructure: double-entry ledger systems, idempotent transaction processing, KYC/payment integrations
• Cloud & DevOps: AWS (EKS, Lambda, SQS, Bedrock, DynamoDB, CloudWatch), Azure, CI/CD, AWS CDK
• Performance optimization: reduced critical API response times by 40 to 60 percent on 100GB+ datasets
• Multi-tenant SaaS: architected LMS platform used across 18 global organizations
• AI integration: production AWS Bedrock pipelines with deterministic fallback architecture
Recent work:
• Built a international remittance platform processing ~50K daily transactions with fault-tolerant ledger architecture
• Architected and shipped backend infrastructure for a fintech savings platform on AWS
• Designed real-time interbank payment APIs with zero-downtime requirements
How I work:
I focus on scalable architecture, reliability, and maintainability. I typically start with a short technical design document outlining tradeoffs before implementation. Financial and transactional paths are always heavily tested and instrumented.
Available for:
• End-to-end backend system development
• Fintech/payment infrastructure
• API architecture and integrations
• Performance optimization
• Senior engineering leadership on existing teams
Kind regards,

Kickoff and access setup
I get read only access to your SQL Server environment, confirm the queries and endpoints in scope, and align on the deliverables for your tier on a short kickoff message.
Baseline diagnostics
I profile your slowest queries, capture execution plans, and identify bottlenecks across the application, query, and index layers using Query Store, SET STATISTICS IO, and Management Studio.
