Vinay S.

Remote Zero Knowledge technologies developer in India (UTC+6)

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. Why I’m Excited to Join Your Team I am eager to bring my expertise in Web3, backend development, and data engineering to a forward-thinking organization. My ability to conceptualize and deliver complex solutions, combined with my passion for blockchain and distributed systems, positions me to contribute meaningfully to your vision.

Vetted Zero Knowledge technologies developer in the United States (UTC-7)

Hi there! **I'm Steve, an award-winning software developer** and **creative problem-solver.** As someone who has been **programming for 16 years**, I have extensive startup and freelance experience which I am excited to leverage to make great things happen -- _fast_. I am built to rapidly craft high-quality, **user-centric software that is beautiful** inside and out. I've done a ton of **Python** (15 years), **JavaScript** (7 years), and concurrent **Go** programming (14 years) on the backend, plus many years of **React** (7 years) and **Svelte** (5 years) on the frontend. Lately I've been creating **RAG-enabled AI chat bots** that answer questions about an arbitrary data set (e.g., company documents or instructional videos). In my personal time I've been learning Kotlin Multiplatform and Arduino, and writing a compiler in RISC-V assembly. Thanks to LLMs -- specifically Claude 3.5 Sonnet, GPT-4o, GPT o1-preview, and GPT-4 before that -- my programming productivity has approximately doubled, meaning **I get $300 worth of programming done per hour, at the highest quality**; I do in 1 hour what mid-level devs need 5+ hours to do, _and_ their code is buggier. Additionally, I am accustomed to playing the role of startup CTO, and I'm looking to do more work as a fractional CTO. This is especially valuable for projects that need software built _and_ **need help clarifying** which approaches, technologies, and services should be used to solve a problem in the most efficient way. In 2022 I was brought into a project after the founder read about me in a book. Together with her team, **the software I designed and led the development of has won many international innovation awards** -- so many that this founder was nominated for Person of the Year in 2023, in her home country of Switzerland. I was **recently vetted** by Arc and **I completed their "30-minute" programming exercise in 4 minutes**. My solution was so simple that the interviewer had to triple-check that it was correct. (It was.) I am not usually available, but I am today. _(Note: For these first 2 weeks of January 2025, I am reducing my rate to $75/hour. After that, it will go back up to $150.)_ **Let's do this!**

Curious, passionate, autonomous. I grew the most professionally at Tactill. As a CTO and lead developer, I was assigned the task to redo the product from scratch. The amount of responsibilities, between the design of the architecture, the development of 12 node.js micro-services, their deployment and maintenance and finally the management of other team members and their tasks taught me how to prioritize tasks, manage pressure and properly design a fully featured architecture. One of my proudest contributions was the project that I was working at [mims.ai](http://mims.ai/). I worked on the multi agent symbolic AI system. Right from the start I could tell that the system was designed around actor oriented programming principles and I suggested that we use an existing actor programming library instead of doing it by hand with golang channels. After a month of work to integrate the library and 2 more months to redesign part of the system our code had shrunk by more than 40%, the design was easily understandable and the speed of the system increased 50x thanks to the use of the lock free queues provided by the library. I also added tools to debug and test the system that helped us to go forward without regression. Additionally, my coworkers would say I'm knowledgeable, that I'm not afraid to get in the dirt or stir it if necessary and that I'm reliable, helping as soon as I can.
