Blockchain backend engineer specializing in crypto infrastructure: BTC, ETH, TRON, and Solana indexers, wallet and MPC custody platforms, and event-driven transaction pipelines in Go and Python. I build the systems that move and secure digital assets at scale, the kind that have to stay correct under load and never double-spend.
Top Rated on Upwork with 100% Job Success, a 5.0 rating across every contract, and 639+ hours tracked. Master of Engineering from IIT Roorkee, ranked first of 150 graduate hires at Reliance JIO.
TOP PROJECTS:
Most crypto-infra work is under NDA — so here's the exception. Real, running systems that show how I build, not just claims:
• Portfolio: [portfolio-gauryvg98s-projects.vercel.app/] — everything below, with live demos and engineering write-ups
• Sentinel OMS [sentinel-oms.fly.dev/] — an execution-integrity order management system I built solo: event-sourced append-only ledger, single-writer Postgres locking, and "halt, don't absorb" reconciliation against exchange truth, running a live bot fleet on Binance Futures.
• chad.wallet (chad-wallet-beryl.vercel.app) — a full Solana trading app. A Go backend aggregates live token data from Jupiter, Helius, DexScreener, GeckoTerminal and PumpPortal behind a cache-first poller and WebSocket hub, and executes non-custodial swaps via Jupiter; Next.js 16 / React 19 trading terminal with TradingView charts, live holders/trades, and Privy embedded Solana wallets.
WHAT I BUILD
• Blockchain indexers and on-chain data pipelines for Bitcoin, Ethereum, TRON, and Solana, reconciled against the chain head with reorg handling
• Wallet, custody, and MPC platforms with signing, multi-step approval, and compliance flows (KYT and AML ready)
• Event-driven backends with Kafka, Redis, Postgres, and RocksDB
• High-throughput APIs and services in Go, Python, FastAPI, Django, and Node.js
• Stablecoin settlement and payment backends, including TRC20 on TRON
• AI agent and automation systems, including emerging agent-wallet and x402 style payment flows
• Distributed ETL and large-scale data pipelines that pull from thousands of changing sources
STACK I REACH FOR
Languages: Go, Python, Java
Backend: FastAPI, Django, Node.js
Data and queues: Kafka, Redis, PostgreSQL, MongoDB, RocksDB
Infra: Kubernetes, Docker, AWS (SQS, SNS, DynamoDB, EKS)
Chain: blockchain indexers, wallet and custody infrastructure, transaction pipelines for BTC, ETH, TRON, SOL, smart contracts, Merkle Patricia Tries
AI: OpenAI APIs, LangChain, LangGraph, Playwright, Dagster
SELECTED WORK
• Crypto custody platform: built a proprietary MPC custody system and the multi-chain indexers behind BTC, ETH, TRON, and SOL, plus wallet, transaction, approval, and compliance flows. The work that mattered most was correctness, idempotent transaction handling, reconciliation against the chain, and approval gates that hold when volume spikes or an external node turns flaky.
• Decentralized storage network: built Go and Kafka pipelines end to end from the blockchain into a centralized backend, with Postgres, RocksDB, smart contracts, and Merkle Patricia Tries, so downstream services always had accurate, ordered event data.
• Real-estate data platform: built an AI-powered scraper and distributed ETL with FastAPI, Dagster, Playwright, and AI agents, handling dynamic anti-bot sites and normalizing large volumes of property data on a schedule.
• Earlier work: real-time engagement systems for the NBA, Golden State Warriors, Paris Saint-Germain, and New Zealand Rugby on a Django and AWS stack, a Go gamification engine on SQS and DynamoDB, and event-driven health-tech that migrated millions of records on AWS SNS and SQS.
WHERE I AM STRONGEST
Getting transaction-critical flows right: idempotency, reconciliation, approval gates, and resilient infrastructure around unreliable external chains and RPC nodes. Async and event-driven by default so the system holds when load spikes. I design the architecture first, name the failure points, then build something the next engineer can read and extend.
HOW I WORK
Clear communication and fast turnaround. Production-grade code with monitoring built in from day one. I take ownership of scope and ship on schedule, and I prefer long-term partnerships where I own the hard parts rather than just closing tickets.
If you are building crypto infrastructure, a custody or wallet system, a stablecoin or payment backend, or a data-heavy platform that has to scale, send me the details and I will tell you exactly how I would approach it and where it breaks at scale.

With over 5 years of experience in the international startup ecosystem, I specialize in building robust, scalable products from the ground up. I am a language and framework agnostic engineer who prioritizes using the right tool for the job without ever compromising on technical integrity.
I began my career in 2019 translating high-level AI research papers into functional products. Since then, I have architected facial recognition systems, image processing pipelines, and LLM-based regulatory software for fintech startups across Europe and Asia.
Since the early 2020s, I have been a core contributor to the DeFi space. I started out designing yield farming algorithms and loan regulatory software for Nord Finance.
I joined BankX in late 2021 as the lead developer back when it was still just a white paper and a set of technical requirements. I built the entire protocol ecosystem from scratch and successfully navigated multiple audits from audit firms like CoinFabrik and Immunefi. The protocol is currently live on 8 different chains including PulseChain.
In August 2024, I co-founded CtrlBit- A SaaS infrastructure platform for Mikrotik network management. The platform is live and handles centralized monitoring, zero-touch provisioning and secure remote access for global ISPs and enterprises at a fraction of the price.
I don't just write code; I build sustainable businesses. I am financially literate, MTCNA certified and experienced in bridging the gap between complex engineering and market-ready solutions. I am currently on the lookout for innovative projects that require high-level technical leadership.
Message me for a consultation. I am generally available during PST and UTC business hours.
