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 leads the architecture and engineering of Faze (faze.fun), a live token launchpad on Arc that puts launch, bonding-curve liquidity, and secondary trading in one place, and owns the real-time multi-chain indexer and API behind it: on-chain trade data across EVM mainnet, Base, Abstract, Robinhood, Solana, and Sui at 1,000+ events per second, with contract event emission shaped to fit the pipeline. Alongside Faze he builds 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.

He is also Co-founder and Principal Engineer at RixoTech, a full-service digital studio spanning software, marketing, video, design, cloud, and AI. Since September 2026 he has been a Software Engineer at StepUp, a Dhaka software agency, owning system design across its product portfolio (architecture, data models, and service boundaries defined ahead of implementation), decomposing designs into agent-executable specifications, and directing AI coding agents through delivery while keeping review, correctness, and integration accountability. He joined StepUp in July 2026 as a QA engineer on Boneek, a multi-tenant e-commerce OS, where he surfaced a settlement defect silently dropping courier cash-on-delivery rows, and he now owns the production fleet behind it: 30 servers on one private VPC, 22 applications, and 11 databases behind self-hosted Coolify, load-tested to 1,200 page views per second and then right-sized from 46 VMs to 31 against a measured 66 per second peak. The product services live in a dozen-service Hono, Next.js, and Drizzle monorepo deployed to Railway, including a rewrite of the Boneek CRM. A contract at Varpa Labs (April–June 2026), the parent organization behind two products, concluded before that. On CareVue (carevue.ai), an AI-supercharged care-home management platform that was already built and remains pre-launch, his contribution was infrastructure and deployment, getting the platform running and shipping cleanly in production, an effectively backend-leaning DevOps role. 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 advised and audited 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 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, where his first paid gig grew into a co-founder and principal engineer role, he built Apeiro, an e-commerce platform selling products and bookable services side by side that has since been rebuilt as a creative design and marketing studio. For six months across 2024–2025 he was the assistant instructor for a ~120-student data structures and algorithms cohort at Interactive Cares, invited back onto the teaching team after completing the same course as a student in the preceding cohort.

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.
