CHRISTIAN KOBE SERGIO

Remote, Philippines•OPEN TO WORK

Fullstack Web3 Developer with a builder's mindset and a track record of leading teams to ship ambitious dApps. As the chief technical architect of a no-code NFT launchpad, I began as the sole developer and later moved into a broader leadership role supporting both our engineering team and the creators building on our platform. I built an ecosystem for NFTs that covers minting, marketplaces, bridging, and staking. I'm now looking to get back to coding hands-on and deepen my understanding of systems and architecture, while continuing to create intuitive, high-impact Web3/Web2 products.

Chief Technology Officer

Oct 2023 - Dec 2025
KingdomlyRemote

As CTO, I built and architected the development of Kingdomly's V2 ecosystem, owning both product direction and technical execution.

What I Led

  • Built a multi-chain permissionless NFT launchpad, marketplace, bridge, and staking platform empowering creators to launch and scale projects without writing code.
  • Directed a 13-person engineering team and aligned product execution with business goals.
  • Collaborated closely with creators and founders to take projects from concept to launch and active secondary market trading.

What I contributed to · Kingdomly

Kingdomly Creator + Mint

I basically started everything from scratch and eventually led the architecture and development of Kingdomly's no-code creator and mint suite, building a generative art engine, IPFS uploader, mint gates, mint phases, mint forms, and an all-in-one admin dashboard that enabled creators to manage their project post and pre-mint drops.

  • Built a full generative art engine supporting layers, traits, rarity, rules, and 1/1 logic.
  • Developed the integrated IPFS uploader for assets and metadata generation.
  • Implemented customizable mint gates for allowlists, presales, and eligibility logic.
  • Designed mint phases with independent pricing and supply controls.
  • Created mint forms for pre-mint registration, KYC, and collector data gathering.
  • Built the admin dashboard for scheduling, quotas, toggles, and live mint management.

Kingdomly Marketplace

Led the design and development of Kingdomly’s cross-chain NFT marketplace, delivering a seamless experience for discovering, minting, and trading NFTs across supported EVM networks, covering both launchpad drops and third-party collections.

  • Shipped an initial marketplace version using the Reservoir SDK, launched on Berachain day one and gaining strong early traction by extending mint drops into active secondary trading during the bera hype.
  • Architected and led the second marketplace iteration built on Seaport and LimitBreak’s Payment Processor, guiding the team in developing a custom indexer, orderbooks, and multi-chain transaction handling.
  • Designed the overall system architecture, unblocked developers on ovreall protocol and indexing challenges, and ensured secure, gas-efficient listings, offers, and royalty enforcing with ERC721AC and EIP-2981 compliance.
Shipped marketplace v2 to alpha version, v1 garnered over $50k in revenue

Kingdomly Bridge

Designed and built Kingdomly's ONFT-powered NFT bridge, enabling seamless cross-chain transfers across major EVM networks and providing creators a permissionless way to make their NFTs bridgeable.

  • Implemented LayerZero ONFT messaging among multiple chains to progress with NFT bridging.
  • Shipped multi-chain support for Ethereum, Arbitrum, Optimism, Zora, Base, and Bera.
  • Created a permissionless bridge setup interface allowing any project to onboard and enable cross-chain bridging without custom contracts.
  • Delivered custom partner integrations, including Honey Jar's multi-chain bridge into the Bera ecosystem.

Kingdomly Staking

Designed and built Kingdomly's permissionless NFT staking platform, enabling any creator to deploy their own audited staking pools and reward their holders without writing code.

  • Engineered the smart contract architecture—audited by Hashlock—that powers secure and flexible NFT staking pools.
  • Developed a permissionless pool deployment flow allowing creators to launch staking programs for any NFT collection.
  • Built yield logic enabling stakers to earn rewards based on the liquidity deposited into each pool.

  • Structured and authored end-to-end documentation covering Creator, Mint, Marketplace, Staking, and Bridge products.
  • Implemented MDX components for guides, examples, and code snippets to improve clarity for all users.
  • Designed a scalable information architecture to keep docs consistent across rapid product iterations.
Reduced onboarding & support overhead by 50% and improved user self-service across all products.

Projects

PRC Inspection and Monitoring System
Production readyPending Pilot Test

Designed and developed an automated Inspection & Monitoring system for the Professional Regulation Commission (PRC) in collaboration with the Board of Nutrition and Dietetics (BOND). This was my thesis project, built to replace the manual, fragmented workflows used to inspect and evaluate compliance among HEIs and hospitals nationwide.

  • Built a multi-tenant web platform supporting five user roles — PRC Board Members, ACD, Regional Offices, Oversight Commissioners, and HEIs/Hospitals — each with separate portals.
  • Developed a robust compliance monitoring workflow tailored for PRC BOND's needs, replacing the accreditation-focused legacy system with one optimized for inspection cycles.
  • Implemented tools for real-time inspection tracking, document submissions, findings, recommendations, and nationwide compliance coverage.
  • Improved operational efficiency by enabling board members to complete their three-year inspection cycle across all regions more effectively.
  • Provided direct access to stakeholders and board members throughout development, ensuring the system aligned with real-world workflows and department needs.

The system includes five separate deployments, each with role-specific features:

  • Client: prc-iam-client.vercel.app
  • PRC Board Members / Secretaries: prc-iam-prb.vercel.app
  • Accreditation Compliance Department (ACD): prc-iam-acd.vercel.app
  • Regional Office (RO): prc-iam-ro.vercel.app
  • Oversight Commissioner (OC): prc-iam-oc.vercel.app

Tenelos — Tennis ELO Rating System
Production deployedFreelance Project

Built Tenelos, a complete tennis ELO rating and match analytics system. I handled everything from complex data transformation to developing the fullstack platform that powers player rankings, statistics, and match predictions.

  • Processed and cleaned large volumes of inconsistent Excel match records using Python ETL scripts, turning raw tennis data into a structured, usable dataset.
  • Worked closely with the client to prototype the system — iterating on wireframes, ranking logic, and UX through multiple feedback cycles.
  • Developed a complete player analytics experience including profiles, head-to-head records, match histories, and performance summaries.
  • Implemented ELO-based player rankings with dynamic updates after each recorded match.
  • Added data visualizations using Chart.js to display player performance trends, win/loss charts, H2H statistics, and ranking changes.
  • Built a full admin interface for managing players, match data, ranking updates, and overall site configuration.
  • Improved platform visibility by implementing SEO optimizations and enabling web crawling for public rankings, player profiles, and match records.
  • Delivered a polished fullstack platform with authentication, dashboards, automated data ingestion, and production deployment.
