Dear Hiring Team,
I am excited to introduce myself, Vinay Sawant, a seasoned Software Engineer with over 11 years of experience delivering innovative solutions in E-Commerce, Fintech, Healthcare, and Web3 domains. My career is defined by a passion for cutting-edge technologies, particularly in blockchain, distributed systems, and backend development, where I specialize in building high-performance, secure, and scalable systems that prioritize data integrity and low latency.
Technical Expertise in Blockchain & Distributed Systems
My five years of dedicated blockchain experience include designing and implementing novel consensus mechanisms and cryptographic protocols for Layer 1 and Layer 2 blockchains. Notable achievements include:
- Consensus Innovation: Spearheaded the creation of Proof of DTS for a high-speed Oracle Layer 1 blockchain and Proof of Claim for the Versatus Layer 1 chain, collaborating with leading cryptographers to optimize throughput and finality.
- Cryptographic Protocols: At Holonym, I engineered a distributed private key computation system using elliptic curve multiplication and integrated zero-knowledge proofs (ZKP) to enable privacy-preserving authentication and undercollateralized DeFi use cases.
- Distributed Systems: Built a decentralized task scheduler at Versatus Labs using RaptorQ for efficient UDP broadcast and implemented threshold signatures/DKG to secure network operations. Additionally, I contributed to EigenLayer’s Active Validation Service (AVS), leveraging shared security models.
- Layer 2 Development: Led the development of the Lasr L2 Chain and a custom verifier for EigenLayer, optimizing staking contracts and node infrastructure.
- Hybrid Consensus: At SupraOracles, I integrated nested DKG, BLS signatures, and a Tribe-Clan model to achieve high throughput (QPS) with low latency.
Beyond blockchain, I have a strong foundation in advanced analytics, machine learning, and backend development. I pioneered Kartavya, an intelligent delayed queue system for managing delayed actions, and engineered a scalable Event Notification Engine delivering 10 million notifications daily. My work in Fintech includes leading end-to-end backend development for SuperMoney and using computer vision and deep learning to build a Smart Document Detector. Additionally, I crafted a Movie & Music Recommendation Engine for BookMyShow, addressing the ColdStart problem for 40 million users, and drove data engineering efforts that reduced default rates by 40% for short-term loan predictions at SuperMoney.
Technical Leadership & Impact
As a technical leader, I have architected groundbreaking systems like Human Keys, deriving cryptographic keys from human attributes while preserving privacy, and contributed to Bitcoin-related technologies, including familiarity with Taproot and Schnorr Signatures. My projects span data engineering, data modeling, machine learning, deployment, unit testing, monitoring, and A/B testing, showcasing my ability to deliver end-to-end solutions. I thrive in remote-friendly environments and am adept at collaborating with cross-functional teams to drive innovation.
