Everything I’ve built, and who it helped

For years, I’ve been building things — inside companies, in the open, and on the side. Most of it was never going to make money. I built it because the problem was interesting, because nobody else had fixed it yet, or because I wanted to understand something well enough to write it down.

25M+ users: Be's super-app, whose internal platform team I led
300K+ students: Geniebook, as technical lead
10K+ orders a day: Gearment, on the Go services I architected
20+ engineers: the department I run today

Ownership is labelled on every entry: a patch to someone else’s project is never listed as mine, and client work appears only as sanitized principles and outcomes.

grpcx
2026
Own project Active
An open-source Go framework, actively maintained, that wires those concerns in once and exposes them the same way across gRPC and REST.
- Go
- gRPC
- REST
- Protobuf
- Observability
View repository (opens in a new tab)
Every new service re-implemented the same plumbing — server lifecycle, structured errors, i18n, auth, observability — slightly differently, so how reliable a service was depended on who happened to write it. Backend teams standing up new gRPC and REST services. A team can start a service with the reliability primitives already in place, instead of bolting them on after the first production incident.
Yuzu Money
2025
Work project Velocity Labs Active
Technical Lead on Yuzu — the services behind accounts, balances, and yield tracking, backed by institutional-grade risk management on tokenized real-world assets.
- Go
- PostgreSQL
- Backend APIs
Visit yuzu.money (opens in a new tab)
Yield products are usually only legible to people who already understand the mechanics underneath them, which puts them out of reach for everyone else. People who want savings to earn yield without learning how the underlying protocols work. Saving and earning are presented as ordinary money movement rather than as protocol operations the user has to reason about.
Perp CEX
2025
Work project Velocity Labs Active
The backend for a perpetual futures exchange (perp CEX), built for an overseas client.
- Go
- Trading systems
- Backend APIs
Visit Velocity Labs (opens in a new tab)
A perpetual futures venue needs a matching engine, margin and liquidation logic, and market data infrastructure that hold up under real trading volume, not just a demo. Traders on a perpetual futures exchange, for an overseas client. The client got a trading venue built to run reliably under real trading volume rather than a prototype.
Gearment Platform
2023
Work project Gearment Active
Led the architectural move from the legacy monolith to Go microservices, and built the shared framework, tooling, and cloud infrastructure other teams build on.
- Go
- Kubernetes
- AWS
- Prometheus
- OpenTelemetry

Vietnamese analysis for Elasticsearch
2020
Contribution to another project Complete
Contributed a merged upgrade bringing the plugin to Elasticsearch 7.5.1, plus a separate follow-up proposal for lowercase tokenization that was closed without merge. The project belongs to its maintainer — these were patches to their work.
Upstream duydo/elasticsearch-analysis-vietnamese 563
- Java

- Open source
View merged version upgrade (opens in a new tab)
The community Vietnamese analyzer had fallen behind Elasticsearch releases, so upgrading the cluster meant losing Vietnamese tokenization. Teams running Vietnamese-language search on Elasticsearch, and the maintainer of the analyzer plugin they depend on. Vietnamese-language search users could move to the then-current Elasticsearch 7.5.1 release without giving up the analyzer they depended on.

Useful production lessons often stay in private notes, while public technical writing gets flattened into generic tutorials that omit the trade-offs. Vietnamese developers who want practical engineering notes without tutorial filler or sponsored content. Readers get production lessons without the tutorial filler, and every article passes through the same evidence and editorial gates before it publishes.
TrendyPod
2026
Personal side project Active
Built a private-source research dashboard and staged pipeline that collects research sessions, cross-checks niche signals, and records GO/no-go decisions in one operational workspace.
- Python
- AI research workflow
- Data pipelines
- Vercel
No public link
Private research workspace — no public access
Trend discovery, competitor evidence, buyer context, and niche decisions lived in separate tools, making it hard to tell which idea had enough evidence to pursue. Ecommerce operators researching product niches across fragmented demand and marketplace signals. A niche can move from a loose trend signal to a reviewable research record instead of relying on screenshots, memory, or one marketplace metric.
POD Supplier Benchmark
2026
Personal side project Active
A private indexing and benchmark workspace that normalizes supplier catalog data into a consistent comparison model behind an authenticated interface.
- Data indexing
- Benchmarking
- Web application
No public link
Private operational tool — no public access
Supplier catalogs, variants, prices, and fulfillment coverage are published in incompatible formats, so comparisons become manual and quickly go stale. Ecommerce operators comparing print-on-demand suppliers and product catalogs. Supplier selection can be reviewed from one structured dataset rather than rebuilt from separate catalog pages and spreadsheets for every product idea.

Libraries, generators and images I wrote and maintain.

go-s3-sharing Go 2025 Stable A minimal Go proxy serving private S3 resources behind a customizable secret-based auth check.
Serving a private bucket to real users usually means either public objects or bespoke signing code copied between services. Anyone who needs to hand out private S3 objects without handing out S3 credentials. Private assets can be shared through one small, auditable service instead of loosening bucket permissions.

lambda-s3-resizer Python 2025 Stable A Python Lambda that resizes uploads in place under a `resized/` prefix, deduplicating concurrent invocations with S3 object locks instead of a separate datastore.
Event-driven resizing re-processes the same object when events are delivered more than once, and the usual fix is a DynamoDB table nobody wanted to operate. Teams resizing user-uploaded images on S3 without running image servers. Duplicate deliveries stop causing duplicate work, with no extra infrastructure to pay for or maintain.

dataloader Go 2023 Stable A small Go data loader for CSV files, so ingestion starts from working code instead of a blank one.
CSV ingestion is written from scratch on nearly every project, with the same parsing and mapping mistakes each time. Developers loading CSV files into Go programs. A common, unglamorous task stops repeating the same parsing and mapping mistakes on every project.

go-bootstraper Go 2021 Stable A bootstrapper that generates a standardized Go project in one step.
The first day of every new service went to recreating the same skeleton — layout, configuration, Makefile, Docker — and the small differences between everyone's version compounded into real inconsistency later. Developers starting a new Go service under time pressure. New services start from a shared, reviewed structure, so the interesting work starts sooner and the boring parts stop drifting apart.

x-crafter Go 2021 Stable Breaks a working prototype down into a template and rebuilds code from it, so the prototype itself becomes the generator.
A good prototype is the best template you have, but turning it into a reusable generator normally means rewriting it as one. Developers who keep hand-copying a working prototype into the shape of a new SDK or service. Teams can standardize on a real, working example instead of maintaining a separate scaffold that drifts away from it.

gomw Go 2021 Stable A small framework that makes composing Go HTTP middleware quick enough to be the default choice.
Cross-cutting concerns end up inlined into handlers because writing middleware correctly is more ceremony than the concern deserves. Go developers writing HTTP middleware. Logging, auth and tracing can stay out of business logic without the middleware being a chore to write.

logrgorm2 Go 2021 Stable A logr logging driver for GORM v2.
GORM's own logger sits outside the application's logging pipeline, so database logs miss the context every other log line carries. Go teams running GORM v2 in a service that already standardized on logr. Database logs flow through the same structured pipeline as everything else, so a request can be followed end to end.

jsoncase Go 2020 Stable Converts JSON keys between casing conventions, so snake_case and camelCase stop being a reason to fork a model.
One consumer wants snake_case, another wants camelCase, and the usual answer is duplicated structs kept in sync by hand. Go services integrating with APIs that disagree about JSON key casing. Casing becomes a transport detail handled in one place instead of duplicated structs kept in sync by hand.

Quantum Computing Race 2026 Not published 2026 Complete Built an evidence-synthesis report that separates physical scale, fidelity, logical error correction, access, product maturity, and vendor targets; each material claim is tied to a cited source and caveated by evidence level.
Superconducting, trapped-ion, neutral-atom, photonic, topological, and annealing systems publish metrics that are not directly comparable, while roadmap claims are often presented beside demonstrated results. Technical leaders and investors comparing fast-moving quantum-computing platforms without relying on raw qubit counts or vendor roadmaps alone.

We Don't Give AI Autonomy. We Allocate It. dev.to 2026 Published AI autonomy isn't a single on/off switch — it should be allocated per task by reward, risk, and available evidence, with workflows designed as graphs of specialized nodes and explicit decision boundaries.
Treating AI autonomy as a single on/off switch ignores that different tasks carry different reward, risk, and evidence — one blanket policy ends up either too cautious or too reckless. Engineering leaders deciding how much autonomy to grant AI agents in a workflow. Humans keep the high-stakes calls while AI handles verification and preparation, instead of one blanket autonomy setting applied to every task.
