I want to create software that feels inevitable after it exists: clear tools, reliable infrastructure, real-time products, and open-source foundations that help other builders move faster.
Portfolio | Projects | Case Studies | Architecture | Contact
I do not want my GitHub to look like a resume pasted into Markdown. I want it to feel like a workshop.
This is where I shape backend ideas into tools, systems, patterns, and products. Some projects are production-grade. Some are experiments. Some are small utilities that come from repeatedly feeling the same friction and deciding to remove it.
The long-term direction is simple:
- Build open-source tools that make backend development calmer and clearer.
- Create real-time systems that feel alive without becoming fragile.
- Turn production lessons into reusable architecture, libraries, and public writing.
- Keep learning in public, shipping in public, and improving the craft.
| Direction | Why it matters |
|---|---|
| Open-source backend tools | Small, sharp utilities that remove repetitive backend work and improve developer experience. |
| Real-time product infrastructure | Chat, video, live workflows, queues, events, and systems that keep people connected. |
| AI-assisted operator systems | Tools that help support, CRM, and business teams work faster without losing control. |
| Database performance craft | Better schemas, indexes, queries, and data flows for products that need to stay fast as they grow. |
| Beautiful engineering documentation | Architecture notes, tradeoffs, and case studies that make complex systems easier to understand. |
I like software that has a strong internal shape.
- APIs should feel predictable.
- Data models should explain the business.
- Background jobs should be observable.
- Real-time features should degrade gracefully.
- Developer tools should be boring to install and satisfying to use.
- Production code should respect the next engineer who has to debug it at 3 AM.
These are the kinds of public projects I want more of in this profile:
| Project | Idea |
|---|---|
| compare-guard | Chainable comparison helpers for direct values and nullable nested object paths in JavaScript and TypeScript. |
| Object Creator | A utility for creating nested JavaScript objects from string paths and dynamic structures. |
| Backend utilities | Reusable helpers for validation, object modeling, API behavior, and safer TypeScript workflows. |
| Architecture demos | Small but complete examples of queues, caching, WebSockets, auth, deployment, and observability. |
| Performance notes | Practical experiments around PostgreSQL, Redis, query plans, and API latency. |
| Language | Evidence |
|---|---|
| Rust | rust-signalforge, an async Axum/Tokio API with typed Serde models, recruiter signal scoring, service health monitoring, structured logging, health endpoints, and integration tests. |
| Go / Golang | Quit Together, a Go platform for quitting smoking with signed-session auth, progress tracking, calendar check-ins, community posts/reactions, image uploads, PostgreSQL persistence, Neo4j recommendations, Docker Compose, and go test ./... verification. |
The dream matters, but I also care deeply about shipping real systems that survive real users.
| Signal | Evidence |
|---|---|
| 5+ years building software | Backend, full-stack, real-time, database, and infrastructure work across production systems. |
| Engineering leadership | Led and supported a backend team of 8 engineers through planning, review, delivery, and debugging. |
| Reliability | Maintained 99.9% uptime on a production backend platform. |
| Performance | Reduced API latency by 40% through backend and database improvements. |
| Real-time scale | Built and supported real-time systems serving 500+ concurrent users. |
| Trading and payment systems | Built backend services for gold, crypto, wallet, payment, and real-time market workflows. |
| Enterprise platforms | Worked across ERP-style modules for process, projects, warehouse, finance, messaging, notifications, and files. |
| Web3 product backend | Built authenticated Telegram Mini-App backend surfaces with TON wallet validation, treasury, referrals, rewards, games, uploads, and live stats. |
| Healthcare product workflows | Shipped physiotherapy product surfaces for posture, range-of-motion, and movement-assessment workflows. |
