From workflow to service boundary.
Clarify the user and operator need, model the data and integration edges, then turn an ambiguous workflow into a focused, buildable product slice.
SOFTWARE PRODUCT BUILDER / ENTERPRISE PLATFORM
Modernize the platform.
Make the path visible.
I turn legacy workflows and ambiguous platform needs into API-backed, reviewable systems - with C#/.NET backend depth, migration discipline, and AI-assisted delivery.
POSITIONING Hands-on enterprise platform builder for modernization, APIs, integrations, cloud delivery, and accountable AI workflows.

01 / ROLE FIT
Build what has to survive
the handoff.
My strongest fit is where a team is modernizing real systems while still needing product judgment, backend depth, cloud delivery, and fast but reviewable execution.
Modernization with visible control.
Analyze legacy Oracle PL/SQL and Pro*C APIs, decompose the work, preserve traceability, and plan reviewable C#/.NET delivery with tests and progress gates.
Faster loops, accountable results.
Use MCP, repository context, structured outputs, and Codex-assisted implementation while keeping permissions, human review, and operational evidence explicit.
02 / FEATURED CASE · MODERNIZATION
Controlled PL/SQL and Pro*C
to .NET migration.
Legacy API work is where platform judgment matters: understand the source, preserve behavior, define a target boundary, and make every step reviewable.

Recent work applied AI-assisted analysis and .NET migration planning with task decomposition, review gates, tests, progress visibility, and traceable evidence.
01
Inspect the source
Understand the legacy API behavior, data dependencies, contracts, and operational constraints before choosing a target shape.
02
Decompose the move
Break the work into focused API and service tasks so progress, risk, and review boundaries stay visible.
03
Verify the target
Use tests, review gates, traceable findings, and handoff evidence to make modernization safer to operate.
WHAT I OPTIMIZE FORModernization that reduces risk without losing the evidence trail.
03 / BUILD EVIDENCE
Platform evidence,
with useful breadth.
Migration is the main story. These selected systems show the supporting range: traceable APIs, enterprise context, workplace integration, and evidence-led retrieval.
A1API DELIVERY / TRACEABILITY
398 APIs. 235 work records.
Correlated a large API inventory with work records to preserve source traceability across analysis, implementation planning, and verification.

04 / WORKING METHOD
Speed with
visible judgment.
AI makes the loop faster. Engineering makes the result trustworthy. My workflow keeps both visible: context first, focused build, evidence, review, operation.
“The best tool workflow is the one another engineer can understand, review, and use.”
01Inspect
Read the existing system, contracts, data, and operating constraints.
02Specify
Turn an unclear opportunity into a focused, testable product slice.
03Build
Use AI-assisted development to move quickly while keeping changes reviewable.
04Operate
Validate with working evidence, document the boundary, and hand off a useful service.
