How I solve problems.

Selected engineering work, summarized without company-specific implementation details or internal metrics.

01 / PERFORMANCE

Making slow APIs more efficient

Django ORMPostgreSQLRedis

The problem

Data-heavy API endpoints became slow as the amount of data and related records increased.

Investigation & implementation

I traced request time through application logs and database queries, checked query counts, and reviewed query plans to identify expensive operations. I reduced repeated database access with appropriate related-object loading, refined filtering and pagination, and reviewed indexes against actual query patterns. Where suitable, I used Redis caching and moved non-interactive work into background tasks.

What improved

Less redundant database work and a more efficient request path. I checked response correctness alongside query counts and request timing to make sure the changes addressed the bottleneck.

02 / RELIABILITY

Handling retries and concurrent requests safely

TransactionsIdempotencyBackground jobs

The problem

Repeated payment notifications, failed jobs, and overlapping requests could cause duplicate processing or inconsistent application state.

Investigation & implementation

I reviewed state transitions and failure paths, then made repeated operations safe to process. Payment handling checked provider references and existing payment status before applying changes. I used atomic transactions for related database updates, appropriate concurrency controls for shared state, and retry-aware background jobs with logging to investigate failures.

What improved

Repeated notifications could be recognized without applying the same payment twice, related updates stayed consistent, and failed work could be investigated and retried more safely.

03 / AWS & OPERATIONS

Deploying and maintaining production services

AWSLinuxDeploymentRecovery

The responsibility

Taking backend applications from development into a maintainable production environment, with controlled access and a practical recovery process.

Implementation & operations

I handled application deployment and server configuration, separated environment settings and credentials from source code, and managed access according to operational responsibilities. I used application and server logs, service checks, and scheduled-job checks to investigate issues. I also worked on automated database backups, retention, and restore procedures, checking restored data and application behavior during migrations and recovery work.

What this enabled

A clearer deployment and troubleshooting process, controlled access to operational resources, and a repeatable path for restoring application data when needed.

03 / The person behind the code

Hi, I’m Wai Yan.
I build with purpose.

I’m a Python web developer who enjoys turning complex workflows into clear, useful software.

My work spans travel platforms, construction and workshop management systems, chatbot applications, and NLP integrations. Across these projects, I’ve worked on REST APIs, business logic, reporting, and the connections between different services.

Django is at the heart of my toolkit. I also work with Flask, FastAPI, and Odoo, alongside PostgreSQL, Redis, and Celery. At Visit77, my backend work includes API development and deployment, with caching and background processing to improve performance and reliability.

I like to start by understanding the problem and the people using the system. From there, I focus on practical solutions, clear communication, and improving the software as requirements evolve. I’m always learning and enjoy taking on challenges that broaden how I think about building for the web.
