full-stack + web3 + systems

Full-Stack, Web3 & Automation EngineerMumbai, India

I turn sharp technical ideas into products that feel fast, clear, and hard to ignore.

I build the parts that usually get split across three different engineers: smart contract logic, automation-heavy backends, and polished interfaces that make serious systems feel usable. This portfolio pulls from real exports and real repositories so the signal lands quickly.

Web3 clients, automation clients, and product clients all get the same thing here: proof, range, and a fast way to contact you without hunting around the site.

where I create the most leverage

Web3 delivery with real context

TRON, token swaps, NFT minting, wallet flows, DAO tooling, and backend logic for blockchain-adjacent products.

Bots that do actual work

Discord verification, community automation, voice + LLM integrations, workshop bots, and utility-driven operational tooling.

Systems and full-stack execution

Observability platforms, classroom monitoring, dashboards, queue-driven pipelines, and polished frontend delivery.

Private builds worth mentioning

Case management, finance, mobile, trading, and search products now show up as visible portfolio categories instead of hidden work.

Background

Computer Engineering track at Rajiv Gandhi Institute of Technology, with enough technical range to move from low-level thinking to product-facing delivery without losing the thread.

Core Stack

Java, C++, API Development, Web Development, Discord, Web Application, C, JavaScript

Communication

Native or Bilingual English and Hindi (Native or Bilingual). Strong fit for fast-moving global client communication.

Portfolio direction

get in touch

If the brief is ambitious, messy, technical, or all three, this is where the conversation starts

The point of this site is to make one impression clearly: you are not hiring a template-level developer, you are hiring someone who can think through systems, ship the product, and make the result feel sharp.

If the client wants someone who can translate rough ambition into shippable software, this section should feel like the obvious next step.
