Hi, I'm Branko. I am looking for a position in a small team where I can wear multiple hats: building features, handling support tickets, writing documentation, SEO.

I have an engineering degree in Geodesy/GIS and 5+ years of customer support experience. I've developed products like a text analysis tool, a fishing logbook app, and an app for easing certain customer support tasks (links on website).

If you need someone who is just as comfortable handling support and documentation as they are writing code, I'd love to chat.

Location: Netherlands / GMT+2 / Remote: Yes. Experienced with US / UK clients; open to timezone overlap.

Willing to relocate: No, occasional travel OK.

Technologies: Backend architecture, data-intensive product systems, event-driven systems, low-latency pipelines, analytics infrastructure, search/retrieval, AI, Node.js/TypeScript, ClickHouse, DuckDB, PostgreSQL, Redis, Elasticsearch/OpenSearch, Vue, Tailwind.

Résumé/CV: Available upon request LinkedIn: https://www.linkedin.com/in/geert-brits/ Email: gbritsgmailcom

Hands-on principal engineer with 20+ years across backend systems, data-heavy products, search/retrieval, internal tools, and founder-led product work. Technical co-founder, CTO/CPO, architect, fractional technical lead, and engineering owner.

I work best where the business goal is clear but the technical shape still needs senior ownership: unclear requirements, fragmented tools and data, API boundaries, retrieval quality, and architecture that has to stay understandable as the product grows. I can own the technical architecture and system shape where needed, and I stay close enough to implementation to keep latency, operability, failure modes, and tradeoffs grounded in reality.

I work across the whole product system: internal tools, backend services, data/retrieval layers, API contracts, observability, and production behavior.

Selected work: Fractional principal engineer / architect for ground-up KPI/analytics platform rewrite (5-person team); company later exited for ~€10M. Technical founder / CTO / CPO for market-intelligence SaaS: live matching of 1M+ dynamic segments against continuous on-chain/off-chain streams; ClickHouse-backed pipelines processing billions of rows/day with near-real-time downstream availability. Marketplace search/matching rewrite (Elasticsearch, percolator-style saved searches, high-volume notification infrastructure) while keeping the live platform in production.

Looking for freelance, contract, fractional CTO, principal engineer, or technical lead roles where one senior person needs to hold the whole system in their head. Also open to full-time opportunities for an exceptional fit. Best fit: backend-heavy products, analytics/data infrastructure, complex internal tools, search/retrieval systems, or early-stage teams that need architecture + implementation depth without a large engineering org.

Location: Remote (Worldwide / Americas Timezones)

Remote: Yes

Technologies: Systems Architecture, Backend Infrastructure, Ruby on Rails, GraphQL, Node.js / Next.js, Cloud-Native AWS - GCP, AI/ML Pipeline Integrations, Telemetry, CI/CD Automation.

Resume: https://lucasarruda.com

Email: lucasarruda - gmail

Staff Engineer / Lead Architect with 15+ years of experience specializing in high-stakes infrastructure, system overhauls, and early product velocity. I partner with tech leaders and founders as an embedded, hands-on technical consultant (15–30h/week) to bridge the gap between initial demos and enterprise-ready systems.

What I specialize in tackling:

- Applied AI & Automation: Integrating AI engines for practical backend workloads, including image classification pipelines, automated log processing, and embedding security scanners into CI/CD workflows to catch and patch vulnerabilities early.

- HealthTech & Diagnostics: Architected platforms integrating complex clinical diagnostic engines, lab systems, and data pipelines with ironclad compliance, deep telemetry, and strict authorization layers.

- Scale & Telemetry: Re-engineered legacy backends, database schemas, and standalone telemetry engines to smoothly process heavy, live data flows and scale to millions of users.

- High-Velocity E-Commerce: Built complex payment gateways, transactional networks, and checkout pipelines designed to handle high-stakes flows cleanly without failure.

- Technical Leadership & Mentoring: Led, unblocked, and upskilled engineering teams to level up implementation paths, accelerate prototyping velocity, and establish sound architectural blueprints.

Looking for direct engagements with founders, VPs of Engineering, or CTOs needing an autonomous technical leader to own core infrastructure paths without executive overhead. Direct client engagements only; no third-party placement agencies.

Email: pedro@pedroalonso.net

Full-stack engineer, 15+ years. Currently wrapping up a contract at Xero building the external API gateway for their financial analytics platform. Before that I built and shipped ReframeHQ solo, an AI product-photo app for Shopify merchants, still live. Modal GPU inference pipeline, background workers, automatic credit refunds on failed jobs, zero-downtime deploys on Dokku. One person running a GPU pipeline in production.

I write detailed, honest build logs of my AI/systems experiments, measured results, not hype (e.g. building a recommender in pure Postgres and watching the embeddings lose to ORDER BY count(*)): https://www.pedroalonso.net
