I'm a builder and researcher based in Dhaka, Bangladesh. I work at the intersection of blockchain security and development, full-stack software engineering, and applied research:
- 🔐 Blockchain Security & Development — smart contract auditing, Solidity development, vulnerability research, and protocol security reviews.
- 💻 Full-Stack Development — end-to-end web applications, APIs, databases, and deployment pipelines.
- 🔬 Research — technical research on blockchain, Web3, software engineering, and general technology topics, distilled into write-ups and reports.
Blockchain Security & Development
- Smart contract security research and Solidity development
- Access control, oracle manipulation, accounting invariants, and AMM hook-based bugs
- Foundry invariant suites, Slither / Aderyn static analysis, and manual line-by-line protocol reviews
- Active warden: Code4rena, Sherlock, HackenProof, Immunefi, Cyfrin
Full-Stack Development
- Modern frontend and backend development with TypeScript / JavaScript
- REST APIs, database design, authentication, and deployment pipelines
- Building production-ready applications from scratch
Research
- Research on blockchain/Web3, security, and general technology topics
- Technical write-ups, audit reports, and educational content
Blockchain: Solidity · Foundry · Hardhat · OpenZeppelin · Vyper · Echidna · Slither · Aderyn
Web / Full-Stack: TypeScript · JavaScript · React · Node.js · Next.js · Python · PostgreSQL · MongoDB · Docker · Linux · Git

My-Audit-Portfolio- |
Write-ups on Damn Vulnerable DeFi, Ethernaut, and public C4 reports — reasoning, not just answers. |
SELF-Smart-Contract-Auditing-Tool |
CLI orchestrating Foundry tests + Slither + Aderyn with one config; emits a Markdown audit report. |
OMNITRIX_D-APP |
Solidity contracts + frontend with Foundry tests (incl. fuzz) — a working stack, not a tutorial clone. |
Security and applied research methodology.
