Senior Systems Architect and Technical Lead with 20+ years of experience. Current role involves managing teams and high-level architecture for international clients. While enjoyable, it leaves less time to write code or set up servers—the hands-on work I've always loved. Looking for freelance projects (~5 hours/day + weekends) to stay sharp and build interesting things.
Availability: Highly flexible. Easily adjust my schedule to align with US or Asia timezones for meetings and syncs as needed.
Backend & Data: Python, PHP, advanced SQL (MySQL/MariaDB), HTTP/REST APIs, complex web scraping architectures. Infra & Virtualization: Linux (Ubuntu/RHEL) kernel tuning, KVM, OpenVZ, high-availability clusters, AWS/GCP/Hetzner, Docker. Networking & Security: Nginx (caching & load balancing), Cloudflare, OpenVPN, BIND server administration, strict DNS security (DMARC/DKIM/SPF), firewall tuning.
Work Ethic: Detail-focused with zero tolerance for unhandled bugs and noisy error logs. Fast communication, proactive updates, and strict adherence to deadlines are standard.
Due to strict NDAs with current company/clients, public profiles are kept scrubbed. More than happy to complete a small paid test task or a time-boxed pilot project to demonstrate code quality and architectural thinking.
Treating your business as my own means delivering more than just ticket execution.
Focus is always on Cost Optimization: Identifying and eliminating cloud infrastructure waste. Revenue Growth: Structuring robust technical architectures that directly support business scaling. Proactive Prototyping: Suggesting and building architectural improvements instead of just waiting for instructions.

I am a senior Full Stack AI Engineer with 8+ years building agentic AI systems, GenAI products, and AI-driven automation, backed by deep full-stack expertise in Python, FastAPI, TypeScript, React, and Next.js. Proven track record architecting multi-agent workflows and LLM-integrated platforms including an AI-powered ads platform that cut campaign launch time 6× and generative learning tools that reduced educator prep time 45%. Seeking to apply agent orchestration, LLM integration, and intelligent automation to accelerate product innovation and measurable business impact.
I built 3 products from idea to paying customers. So I can help your startup with architecture, implementation plans, and writing specs that you need to keep vibecoding sane. Depending on whether I get into YC (or most likely not, applied with just an idea), I might have free time coming up in the upcoming months.

I’m Mark, a Dutch product designer working from strategy to shipped code. Always have, it’s what got me hooked on design over a decade ago. Since, I’ve worn many hats working in startups and for myself.
I love collaborating with founders and small teams. By working across design, engineering, and product, I help them build simple, effective, and reliable software.
I’m ideally looking for a company where I get to go beyond making pictures of interfaces. A place where I get to work end-to-end from ideas to visuals to the finished product.

I’m a senior generalist engineer with founding-style ownership. I like building systems end-to-end: protocol and product code, backend platforms, infrastructure, internal tools, and product-facing surfaces. Several times I was either an initial or an early hire in small and large-scale projects and products.
For the last two years, I was a founding engineer at Load Network, an early-stage L1 EVM chain with Arweave-based data settlement. I worked across the stack: developed protocol-level abstractions, consensus and execution clients, bootstrapped infrastructure, DevOps, and smart-contract prototypes. I also built private AI agent harnesses, ran multi-agent tests, and used LLMs for spec review and cross-client protocol design research and data gathering.
Before that, I spent six years in gamedev building backend platforms for massive-scale games at Strikerz/UFL (uflgame.com) and Vizor Games. I was an early hire, working directly with the CTO to build the infrastructure and design the system from the ground up. I engineered microservices for matchmaking, game economy/payments, quests, auth, moderation, and data pipelines (Kafka, Postgres, ClickHouse). I also managed Kubernetes, observability, internal admin tooling in Python/JS, and took part in high-stakes production launches.
I built my engineering foundation in enterprise Business Intelligence and Data Architecture. I shipped large-scale data warehouses (OLAP) for global companies (pharma, logistics), writing heavily optimized Oracle PL/SQL and T-SQL.
Open source: Merged contributions to the Ethereum ecosystem, including the Reth client in Rust, Flashbots SUAVE, and Alloy.
These days, I'm spending more time on product-facing surfaces (React, Rails), exploring Zig, and using LLMs for the right dose of entropy and speed.
Looking for: founding engineer, senior/staff software engineer, full-stack or backend roles where broad ownership and technical depth matter.

Do you need the expertise of a seasoned software engineer for a project but don't have the budget for someone full-time? Need to get a project done quickly & well? I'm available 40+ hours/week through August 10th. (After that my availability is more limited since I teach Latin at a small Classical school). Standard Rate: $100/hour
Work experience:
- Built a tool (non-AI) to read Latin texts and generate fully-parsed glossaries. I used this tool in a few Latin readers I've published recently.(Tech: Clojure, SQLite, Ada)
- Built a billing system, using Stripe integration, for a B2B SAAS app.
- Fractional team lead for Learnics. Wrote a bibliography generator that supports MLA, APA, and Chicago style. (Tech: Vue, Firebase)

I took a break from freelancing for a while to run a crazy experiment. 25 projects in 25 weeks. A lot of it was experimental: https://stevenirby.me
It was a lot of fun. I was featured in TechCrunch, Engadget, and many more. I was on the front page of HN 4 times.
So now I'm looking for a freelance position where I can help a team with product development or AI stuff.
