Selected work

Some client work is under NDA. Very mysterious. Mostly databases. What follows is what I can show.

01 In development Independent · 2026 – Present

DockPool

A custom Docker-based PaaS for deploying container images on shared or dedicated compute, with project networking, persistent storage, deployment history, runtime health, and operational visibility.

Problem: Running container workloads often means solving placement, networking, routing, storage recovery, billing, and failure diagnosis as separate operational problems.
My role: Founder and sole builder across product design, architecture, the Rust control plane, SvelteKit frontend, agents, and infrastructure automation.
Work delivered: Built a Rust control plane with PostgreSQL state and Redis/Asynq orchestration
Implemented shared and dedicated compute placement, project networking, persistent volumes, backup, and restore
Built deployment history, bounded logs, runtime health, billing foundations, and production-shaped cluster automation

02 TripEdge · 2025

TripEdge Booking Platform

Backend-heavy product work for a travel booking platform, including hotel and flight integrations, Rust services, Redis-backed performance improvements, and support for customer-facing booking flows.

Problem: Booking flows depend on slow, inconsistent hotel and flight vendor APIs. Latency and reliability were the bottleneck.
My role: Senior engineer across the stack, primary owner of the Rust backend.
Work delivered: Vendor-facing integrations for hotel and flight APIs
Async patterns, caching, and query optimization that cut response times
Booking workflow support in Vue and Nuxt where frontend work was required

03 Archived client work Cognotiv Pte Ltd · 2022 – 2026

PandaiSuite Ecosystem

A suite of training, LMS, HR, and marketplace products. The scope included SaaS feature delivery, monolith-to-microservices migration, infrastructure automation, and shared platform capabilities.

Problem: A growing product family was held back by a legacy Laravel monolith, manual deployments, and duplicated platform logic.
My role: Senior full-stack developer leading delivery across nine products.
Work delivered: Migrated the monolith toward service-based architecture
Built LMS, HR, and marketplace products with tenant-specific storefronts
CI/CD with GitHub Actions and GitLab on AWS
Shared auth and platform capabilities across the product family

What I can help with

If you need a senior engineer who can own technical decisions, implementation details, and delivery quality — without the ceremony.

Backend architecture and APIs

Reliable services, integrations, data models, and production systems that keep working after the demo ends.

Full-stack product delivery

Complete features across backend, frontend, and deployment, with a bias toward maintainability and execution speed.

System modernization

Legacy systems moved toward cleaner boundaries and service decomposition, one deployable step at a time.

Infrastructure and release workflows

Deployment pipelines, containerized environments, and runtime stability that make Friday deploys less of a personality test.

Recent experience

The full chronology lives on the about page. These are the roles that matter most right now.

SELECTIVE FREELANCE PROJECTS

Let’s build something that stays boring in production.

I currently build full-time at Paper.id, but I keep a small lane open for carefully scoped projects. If it fits, the email is right there — I answer project emails myself. Automation has suffered enough.
