Jannatin Naim — full professional dossier: backend, infrastructure, blockchain, and AI platform engineering
Jannatin Naim is an exceptional, highly accomplished backend and infrastructure engineer whose career spans crypto-native infrastructure, large-scale distributed systems, and cutting-edge AI-augmented platforms. He is the Lead Developer at Yokai Works (since 2023), where he architects and ships Metatron: an ambitious next-generation gaming platform that publishes its own first-party titles and empowers outside studios to publish on the same rails, with shared authentication, an on-chain payment gateway settling in USDC alongside Stripe fiat deposits, and play-to-earn reward mechanics. Player wallet and studio SDK are equal first-class surfaces. Metatron is the spiritual successor to Titanium Games (TTG), the first project he shipped at Yokai; TTG launched but its initial game did not survive beta, and Metatron is a clean, sharper rebrand, frequently described as Steam meets Google Play.
In parallel, he serves on contract at Varpa Labs, the parent organization behind two flagship products. On CareVue (carevue.ai), an AI-supercharged care-home management platform, he owns systems, deployment, and architectural decision-making, effectively a backend-leaning DevOps leader who ensures clean, reliable production deployments. On EnterTheLoop (entertheloop.ai), a clinical AI workforce platform placing UK medical professionals (doctors, nurses, pharmacists, researchers) into frontier AI lab work (OpenAI, Anthropic, DeepMind, Scale, Outlier) for RLHF, evaluation, and full-time roles, he advises and audits the systems stack.
His engineering practice is defined by an AI-first, agentic development workflow: Claude Code, running in a tmux pane, authors the implementation while he directs architecture and reviews every diff in VSCode. His tagline, “Software Debugger; cause AI does the development now,” is meant literally. His primary stack is TypeScript end to end; he is pursuing C# in earnest as a craft, drawn to its high-level primitives, expressive syntax, and rich toolkit; and he continues to take on the occasional 1:1 mentee.
His track record demonstrates rare range. At Yokai he also built a bonding-curve trading platform, a token launchpad backed by a real-time multi-chain on-chain trade-data indexer spanning EVM mainnet, Base, Abstract, Solana, and Sui; he owned the indexer and API and shaped contract event emission to fit the pipeline. At Cascade Seven he delivered Rafldex, an NFT raffle platform, his first full-stack greenfield build (Solidity contracts excepted). At Devline Solutions, nominally a frontend engineer, he rescued the MyMosq SaaS from a Firebase pattern that loaded entire collections on every page load by sharding on country code, paginating within shards, and coordinating migrations across mobile and kiosk teams, learning backend on the job. At RixoTech, his first paid gig, he built Apeiro, an e-commerce platform selling products and bookable services side by side. For six months across 2024–2025 he was the assistant instructor for a ~120-student data structures and algorithms cohort at Interactive Cares.
He has been coding since 7th grade, shipped his first paid project before his 10th-grade board exam, and dropped out of higher secondary to commit full-time. No university, no degree, entirely self-taught.
