About Sachin

Sachin H.Status: Offline
Web & mobile dev (with AI/blockchain) | IT support / virtualization
5.0  (1 review)
Akuressa, Sri Lanka - 5:25 pm local time
I’m a full stack mobile and web developer and IT support specialist, helping clients build modern apps and keep their infrastructure stable behind the scenes. On the development side, I work with technologies like Next.js, React, Flutter and Node.js, and I can integrate AI features and blockchain where they genuinely add value (not just buzzwords). On the infrastructure side, I provide remote IT support, server and VM setup (XCP ng / virtualization), domain & DNS configuration, and basic security hardening.

I’m comfortable taking a project from idea to deployment planning, clean implementation, testing, and rollout. I focus on clear communication, practical solutions, and documenting my work so clients aren’t “locked out” of their own systems. If you need someone who can build the product and understand the servers it runs on, I’m a good fit.

Steps for completing your project

After purchasing the project, send requirements so Sachin can start the project.

Delivery time starts when Sachin receives requirements from you.

Sachin works on your project following the steps below.

Revisions may occur after the delivery date.

Workspace Setup

Create (contracts + mobile) with Hardhat/Firebase (or Foundry) for Solidity, Expo CLI for React Native, and the Thirdweb CLI (npx thirdweb create …). This gives you ready-to-compile contract templates, wallet hooks, and typed SDK bindings place

Write & Test Contracts

Extend OpenZeppelin ERC-20/721 (or craft custom logic), add Ownable/AccessControl or UUPS upgradeability, then cover everything with unit tests and static-analysis (Slither, Mythril) so the bytecode is secure before mainnet.

Review the work, release payment, and leave feedback to Sachin.
