[01]$ cat about.md

Engineer, operator, problem solver

I care about systems that survive contact with real users, and teams that keep shipping after the launch postmortem.

Experienced in building and scaling B2B marketplaces, with a strong background in B2B e-commerce, chat applications and startup operations.

Skilled in team management, hiring and streamlining processes. I keep up with tech trends but take a pragmatic approach, opting for custom solutions when necessary.

Highly autonomous and results-driven. I set high standards and focus on execution. Direct and goal-oriented — working with me isn't always easy, but the focus is always on achieving success.

currently

Building products for clients who need senior judgement, not a body in a standup.

$ git commit -m "ship"

[main 4f2a1c9] availability: open

Direct, high standard, low ceremony. I would rather tell you a hard truth early than discover it in production.

B2B marketplaces & e-commerce

End-to-end marketplace platforms: catalog, pricing, quoting, ordering, fulfillment and the back office nobody wants to build but everybody needs.

→Multi-vendor catalog & RFQ flows
→Order, invoice & logistics pipelines
→Payments, wallets and reconciliation

Realtime & chat systems

Presence, messaging, notifications and live collaboration that stays correct under load.

→WebSocket / SSE architecture
→Fan-out, delivery guarantees, history
→Mobile + web clients on one protocol

Product engineering & scale

From a blank repo to production: domain modelling, APIs, infrastructure, observability and the boring reliability work that keeps it alive.

→API design & service boundaries
→CI/CD, containers, observability
→Performance and cost tuning

Fractional CTO & team building

Hiring, onboarding, process and technical direction for founders who need senior judgement without a full-time seat.

→Hiring loops that filter for signal
→Roadmaps and delivery cadence
→Code review culture & mentoring

Tools I reach for, and why

Pragmatic defaults, not dogma. Pick boring technology for the core, sharp tools at the edges.
