XP.NETWORK

Technical Operations & Project Lead

Technical operations and project management for a Web3 startup: a multi-chain NFT bridge, 30+ blockchains, close to $6M raised. I ran the infrastructure with my own hands and the projects around it; every account, credential, deployment and supplier ran through me.

• Ran the AWS staging and production environments: S3, CloudFront, ACM certificates and TLS, domain registration, Cloudflare DNS and redirect rules, registrar and nameserver migrations. Took every build to staging first, then production.
• Secured and provisioned every account the company owned: AWS, MongoDB, Heroku, GitHub, Google Workspace, Dropbox, every social platform. Opened each one, approved the spend, gave minimum access, kept the 2FA on a separate phone.
• MongoDB: cluster setup, upgrades ahead of peak load, queries and direct collection edits. Dropbox Business for the company's sensitive files, with offline backups.
• Built and imaged every employee's machine: Windows, macOS, iOS, Ubuntu. Google Workspace and Apple Business Manager, Google Cloud API keys.
• The company website and docs: bug fixes, forms behind Captcha, weekly docs releases from GitHub to staging to production.
• Audited every subscription with the CTO and closed the ones not needed, which cut the monthly services bill.
• Built the back-office and QA flows behind product launches, and the anti-abuse rules for the Galxe campaigns' free NFT mint: per-wallet caps and time-boxed verification.
• Wrote the weekly investor and community update, pulled from dev, BD, marketing and design and shipped every Sunday; one of two people in the company in contact with investors. Single contact for 19 blockchain grants, from agreement to final payment.
• Managed the 24/7 community team: six people in six countries, rotas, hiring, training, escalation.
• Designed the seven-year legal retention archive when the company wound down: three jurisdictions, 60+ investors, with a README an outside auditor could follow.

Mar 2021 - Feb 2022

XP.NETWORK

Community Lead & Operations

Built XP.NETWORK's early-stage community, support and platform presence from zero, a year before moving into the technical role.

• Worked with the CEO on the first funding round, getting investors onto calls, then on the run-up to the token launch in September 2021, with KOLs I onboarded and managed.
• Created and secured the company's presence on Telegram, X, LinkedIn, Medium, Reddit, Bitclout, Instagram, Discord, YouTube and the newsletter. Every account opened by me, every 2FA held by me.
• Launched the Telegram community and hired its moderators: 24/7 shifts across six countries, rotas, training, escalation.
• Designed and put in place the workflows for internal handoffs, user FAQs, incident escalation and campaign rollouts.
• Point of contact between users and the product and dev teams. AMAs, campaign support, feature launches, and the daily social posting and weekly Medium blogs whenever there was no marketing hire.
• Ran the operational side: contracts, team onboarding, moderator invoicing, tooling.

Jan 2020 - Mar 2021

Nonprofit One

Web & Infrastructure Project Manager

Digital infrastructure and campaign systems for nonprofits, among them Krembo Wings, IGY and the College of Management, plus a WordPress vulnerability scanner we built. My first job in tech.

• Ran the televised fundraising campaigns for Krembo Wings, Latet and Variety: single contact for the foundations, the card companies and the developers. Tested every payment flow and currency, took each build live. Millions of ILS in an hour, on a real-time dashboard, with Google Analytics and Tag Manager behind it and a full data extraction cross-checked before it went to the client.
• Took over the foundations' domains for each campaign: DNS moved to us, mail untouched, every page redirected to the donation page. Domains, subdomains and hosting on S3, Certificate Manager, CloudFront and Cloudflare; kept the hosting and the MongoDB clusters up through the broadcasts.
• The scanner: took its findings on the live sites of retailers and a hardware maker, among others, to the companies themselves, got their digital managers and web suppliers on the phone and got the findings fixed. Set up card payments end to end. Ran the offshore developers.
• Built and kept up the Krembo Wings and IGY websites and registration forms, and a school's site with payment and registration forms: WordPress (Elementor) from Figma, HTML forms, iFramed card payments, QA before every release.
• COLMAN Flix: a Netflix-style platform for the College of Management's online courses. Ran the project, built the demo with our developers and presented it on stage to their executives. Also the help desk and communications lead for the company's nonprofit CRM/ERP product.
• Early on, in 2020, an SEO product: a generator that built sites and backlink blogs; one pilot client on page one for its keywords. Screaming Frog, Ahrefs, Semrush.

Mar 2016 - Nov 2019

Leonardo Hotels

Security Manager

Physical security for a high-traffic hotel: guests, staff and assets, around the clock. Where the security instinct started, well before the infrastructure did.

• Ran the security team: shift scheduling, training, readiness.
• Emergency response, including medical incidents and the fire systems.
• The CCTV upgrade, from deployment to day-to-day operation. In-room safes, door locks and master key access across the property.
• Alerts, lockouts and abnormal activity, resolved in real time. Safety protocols, licensing, and the police and emergency services when it came to that.
