Abubakar Lawan

I’m Abubakar Lawan, a Software Engineer with nearly 5 years of professional experience in building scalable applications and 3+ years specializing in Python/Django. Over the past year, I’ve also developed deep expertise in blockchain and Web3, working extensively with Solidity, smart contracts, and decentralized applications.

My background bridges Web2 and Web3:

- Backend & APIs: I’ve built REST APIs, automation pipelines, and full-scale web apps (including a utility payments platform and subscription management systems).

- Blockchain Development: I design and deploy secure smart contracts (ERC20/BEP20 tokens, DAOs, staking systems, NFT marketplaces) and integrate on-chain logic with real-world applications.

- Security: I’ve completed 6+ audits on CodeHawks, including a formal verification audit with Certora, and regularly use tools like Slither and invariant testing to ensure contract robustness.

- Django & Bootstrap: 3+ years building production-ready applications, with strong knowledge of authentication, admin dashboards, and database integrations.

-React (basic): While not my main stack, I can collaborate effectively with front-end teams thanks to hands-on experience with React in full-stack projects.

-Telegram Automation: I’ve built bots for crypto trade copying, subscription management, message forwarding, and real-time performance tracking using APIs like Birdeye and Dexscreener.

Notable Projects

- Crypto Subscription Bot – Deployed a Telegram bot managing user subscriptions with Stripe integration.

-Trade Copier – Built a bot to copy trades from Telegram signals directly to MT5.

- DAO-Based Governance System – Created a governance framework with token staking and on-chain voting.

- NFT Management – Integrated IPFS storage for NFT images and metadata.

- Healthcare EMR System – Contributed as a junior developer, handling tests, reusable functions, and backend optimizations.

- Utilities Web App – Developed a platform for purchasing mobile data and utilities, with an API for external integrations.

- Security: Slither, Certora, Invariant Testing, Audits (6+)

- Other: Git, Docker, REST APIs, Telegram Bot API, Webhooks

Why Me?

I combine traditional backend expertise with hands-on blockchain development to deliver reliable, secure, and scalable solutions. Whether it’s auditing a smart contract, building a Web3-powered marketplace, or deploying automation systems, I bring a problem-solving mindset, attention to detail, and passion for innovation.

I’m looking for long-term collaborations with clients who want to build meaningful products in Web3, DeFi, SaaS, or AI-driven systems.
