Securing Systems at the Intersection of Cybersecurity & Blockchain

I’m Adarsh Kumar — a Security Engineer With Multi-Year Experience in the Field

Experienced in vulnerability assessment, application security, and smart contract auditing. I hold the Google Cybersecurity Professional Certificate and have published peer-reviewed security research through Springer. My blockchain background isn’t a detour — it’s where I built real adversarial instincts, and I bring that depth to every AppSec, SOC, and blockchain security engagement.

Blockchain Security Engineer

Oct 2024 – Present

Conducted smart contract and application security reviews identifying critical vulnerabilities including reentrancy, broken access control, privilege escalation, and input validation flaws. Reduced exploitable attack surface by 40% through structured remediation workflows and secure architecture improvements. Performed exploit analysis, threat modeling, and root-cause investigation across blockchain authentication systems. Built blockchain traceability infrastructure that reduced counterfeit and fraud incidents by 50%.

Blockchain Developer & Smart Contract Security Auditor Trainee

Jan 2023 – July 2023

Designed and deployed secure smart contracts, optimized gas efficiency, and architected decentralized applications (dApps) using Solidity and Web3.js. Collaborated with cross-functional teams to audit code, integrate oracles, and deliver scalable blockchain solutions aligned with user needs.

Blockchain Developer Intern​ (Full-Stack)

Aug 2022 – Dec 2022

Assisted in developing and testing smart contracts using Solidity, contributing to dApp prototypes. Supported gas optimization efforts and participated in code reviews. Collaborated with senior developers to integrate oracle solutions and document blockchain workflows.

My Services​

I find vulnerabilities before attackers do. From VAPT and smart contract audits to application security and secure architecture — I protect systems across Web2 and Web3.

01

VAPT

I perform end-to-end VAPT on web applications and blockchain systems, identifying exploit paths, broken access controls, and attack surfaces aligned with OWASP Top 10. Every finding comes with structured remediation guidance.

02

Smart Contract Security Audit

Full-scope security audits for ERC-20, ERC-721, and ERC-1155 contracts. I identify reentrancy flaws, logic bugs, ownership vulnerabilities, and replay attack vectors before they cost you — using Slither, Mythril, and manual review.

03

Application Security (AppSec)

Secure code review, threat modeling, and attack surface analysis across traditional and blockchain-based applications. I integrate security into your development pipeline — not as an afterthought, but as a foundation.

Endorsements​

Security isn’t a feature you bolt on at the end. It’s the foundation everything else is built on — and I bring that to every audit, assessment, and engagement.
