Back to original languageAbout Omar
I design and deliver production-ready fintech and crypto platforms – from Go backends to React frontends and AWS infra.
What I bring to your projects:
→ Robust Go/React systems, from MVP to scale
→ Payment and crypto partner integrations (APIs, webhooks, compliance)
→ Solid AWS cloud architecture (Lambda, SNS/SQS, Terraform, Docker)
→ Real-world blockchain experience (EVM, Cosmos SDK, Gnolang)
Currently at Fipto for almost 3 years, developing a B2B platform for payments and wallets (fiat/crypto) on a Go + React/TypeScript monorepo. Key partner integrations: Fireblocks, ClearBank, Modulr, Notabene. Contributions to architecture initiatives: Kinesis → SNS/SQS migration, containerization, QLDB → PostgreSQL migration.
Previously: at Schneider Electric, I led the front-end and back-end of an industrial monitoring platform (Vue.js, Go, InfluxDB). At Wildmoka, I progressively introduced React.js into a legacy jQuery codebase without service interruption, on an AI media platform used by major sports broadcasters.
Core contributor Gno.land (@gnolang) via Samourai World — I work directly on the GnoVM runtime and core protocol (critical bug fixes, PR reviews, compiler robustness).
Founder of Greffon (greffon.io) — a self-hosted app store that allows teams to deploy apps (VSCode, Nextcloud, GitLab, Supabase…) on their own machines, without DevOps complexity. Currently in closed beta.
Remote worldwide. Feel free to contact me to discuss.
