How C1nh Thinks

Not just a list of skills. A disciplined methodology for diagnosing failure modes, simplifying topology, and delivering high-stakes performance.

Case Study: Database Architecture

Hospital EMR: SQL Server CPU 88% ➔ 11%

Context: Enterprise Healthcare System with 200 concurrent physician terminals and 40M patient records.
FAIL STATE:Peak clinical morning hours locked up SQL Server CPU at 88-95%, causing timeout cascading across outpatient registration.
Diagnostic & Engineering Pipeline:
PROBLEM01
Identify Hotspot
Captured sys.dm_exec_query_stats and extended events. Identified TOP 3 billing calculation queries burning 65% total worker time.
Wait: SOS_SCHEDULER_YIELD / CXPACKET
UNDERSTAND02
Execution Plan Inspection
Discovered implicit VARCHAR to NVARCHAR data type conversions forcing clustered index scans on 40M rows instead of index seeks.
Type Precedence Mismatch
ARCHITECTURE03
Covering Index & Plan Stability
Re-aligned Dapper parameter types to exact DB schema and designed filtered composite index with INCLUDE clause for billing status.
CREATE NONCLUSTERED INDEX IX_Bills_Status...
OPTIMIZE04
Eliminate TempDB Spills
Tuned cardinality estimates and replaced multi-statement table-valued functions with inline table functions.
Memory Grant: 256MB ➔ 8MB
SHIP05
Production Release
Rolled out hotfix with zero downtime. CPU stabilized at 11-14% during highest morning load spikes.
CPU 88% ➔ 11% | Queries: 2,400ms ➔ 18ms
MEASURED OUTCOME:Eliminated all timeout errors, freed up 70% CPU headroom without adding expensive hardware.

CRAFTSMANSHIP

Engineering Philosophy

"Don't build software to look impressive. Build software that solves real problems."

01

Solve real problems first

Don't build software to look impressive. Build software that solves real problems.

Avoid speculative abstractions, over-engineered architectures, and premature microservices. Ship working solutions that handle production edge cases.

02

Keep architecture simple & boring

Boring technology scales predictably.

Standard library over unnecessary packages. Native platform capabilities over heavy abstractions. Two files over twenty layers of indirection.

03

Dogfood your own tools

If you will not use it every day, nobody else will either.

C1nhUI, C1nhRealtime, and C1nhTools exist because I needed them in real enterprise products (CRM, Trading, Healthcare EMR). Every component is battle-tested in actual production.

04

Design for production reality

Systems fail at the network and human boundaries.

Defensive timeouts, idempotent operations, network drop resilience, token rotation, and robust offline handling are foundational requirements, not afterthoughts.

05

Automate repetitive cognitive work

Code generation and AI agents should handle the mechanical tasks.

Harnessing autonomous coding agents, Roslyn analyzers, and custom tooling frees engineering time for architecture, domain clarity, and high-leverage decisions.
