Public Skills
change-impact-analysis
by laivannha0202
Map the blast radius of cross-module, public-contract, schema, auth, payment, migration, or shared-library changes before editing and before final review.
dotnet-engineering
by laivannha0202
Work on .NET/ASP.NET Core including APIs, services, EF Core, DI, configuration, auth, async code, and tests.
java-spring-engineering
by laivannha0202
Work on Java/Spring Boot including controllers, services, repositories, validation, transactions, security, JPA, and tests.
software-architect
by laivannha0202
Design boundaries, modules, data flow, interfaces, migrations, and tradeoffs for non-trivial changes without unnecessary rewrites.
devops-engineering
by laivannha0202
Work on Docker, CI/CD, build pipelines, environment config, deployment, health checks, logging, and infrastructure-related files.
flutter-engineering
by laivannha0202
Work on Flutter/Dart apps including widgets, state management, navigation, async APIs, platform behavior, layout, and tests.
python-engineering
by laivannha0202
Work on Python apps/services using project packaging, typing, async, tests, linting, environments, and framework conventions.
implementation-engineer
by laivannha0202
Implement features and refactors carefully while preserving architecture, compatibility, types, validation, tests, and conventions.
fastapi-engineering
by laivannha0202
Work on FastAPI services including Pydantic models, dependencies, async endpoints, validation, auth, OpenAPI, and tests.
auth-security
by laivannha0202
Implement and review authentication, authorization, sessions, tokens, passwords, permissions, roles, secrets, and security-sensitive APIs with server-side enforcement.
dependency-management
by laivannha0202
Change dependencies safely by verifying package legitimacy, pinned/current compatibility, peer/runtime constraints, release guidance, lockfiles, supply-chain surface, and the smallest necessary version movement.
nodejs-engineering
by laivannha0202
Work on Node.js services and tooling with version-aware modules, async behavior, validation, APIs, files/processes, lifecycle, logging, and tests.
nextjs-engineering
by laivannha0202
Work on Next.js apps with version-aware App/Pages Router boundaries, server/client components, routes/actions, caching, data fetching, metadata, images, and deployment behavior.
payment-engineering
by laivannha0202
Implement and review payments as high-integrity state machines with trusted amounts, provider webhooks, idempotency, retries, reconciliation, and order/payment separation.
react-engineering
by laivannha0202
Work on React apps using existing component, hooks, state, routing, data fetching, forms, performance, and testing conventions while preserving rendering and state invariants.
database-engineering
by laivannha0202
Design and modify schemas, migrations, indexes, queries, ORM models, transactions, and data integrity with compatibility, rollback, and existing-data safety.
api-contract
by laivannha0202
Keep frontend, backend, DTOs, schemas, generated clients, validation, status codes, serialization, pagination, and errors consistent end-to-end across producers and consumers.
web-security-review
by laivannha0202
Review web applications for reachable, evidence-backed security risks including injection, XSS, broken access control, CSRF, SSRF, traversal, unsafe uploads, secrets, deserialization, and dangerous execution.
bug-diagnosis
by laivannha0202
Diagnose runtime errors, build failures, regressions, failing tests, integration issues, crashes, and incorrect behavior through reproducible evidence and root-cause hypotheses before fixing.
research-verification
by laivannha0202
Verify current external APIs, packages, versions, framework behavior, security guidance, and documentation with primary sources before coding when repository evidence is insufficient.
test-driven-development
by laivannha0202
Use a pragmatic red-green-refactor loop for behavior changes and bug fixes when the repository has a practical test harness or a focused regression test can reasonably be added.
test-verification
by laivannha0202
Prove engineering claims with fresh project-native tests, type checks, lint, builds, reproductions, contract checks, and final-diff inspection; never report success from expectation alone.
code-review
by laivannha0202
Review changed code for real defects and regressions with context-aware evidence, prioritizing correctness, data loss, security, contracts, state/races, performance, and missing verification over style noise.
context-engineering
by laivannha0202
Control context in large or unfamiliar repositories by building a compact evidence map, reading only relevant interfaces and analogues, and avoiding repeated low-value file loading.
