Hire the Best Haskell Developers & Programmers
in India

good at full-stack development and systems engineering. I have built apps from scratch and scaled them, wearing many different hats from front-end UX to low-level systems programming.

I build production-grade Solana infrastructure and high-throughput data pipelines in Rust. For Backtesting, Wallet Intelligence, Liquidation Bots, Monitoring Protocols. What I do: - Solana indexing and RPC infrastructure: Geyser gRPC streaming, resilient connection pooling, exactly-once data pipelines - Real-time systems with hard latency guarantees (sub-second slot-to-indexed-End to end latency) - Distributed data architectures: TimescaleDB hypertables, horizontal scaling, automatic failover Recent work: Built a production-grade Solana indexer handling 40+ TPS with zero event drops. WAL-based crash recovery, gap detection with RPC fallback, and auto-healing architecture. Designed for 5,000+ TPS mainnet workloads. Core competencies: - Rust · tokio · tonic · axum · TimescaleDB · PostgreSQL - Solana infrastructure (Geyser, RPC pooling, account streaming) - Async runtime internals · low-latency systems · distributed consensus - Zero-copy FFI · WebGPU/WASM · formal verification Also: I write about deep technical topics spanning from Rust internals, distributed systems failure modes, and the parts of infrastructure that break in production. When to hire me: You have a hard infrastructure problem where correctness, latency, and throughput numbers matter. If getting the abstractions right matters more than shipping fast, I'm your engineer. Let's talk: Your problem is hard enough that I should be working on it.

I am a seasoned Backend Engineer renowned for crafting well-structured, maintainable, and high-performance code. My primary domain of expertise lies in Go, though I possess a wealth of experience across various programming languages, including Rust, Python, and Node.js. I specialize in the development of microservices and excel in leveraging cutting-edge technologies for their seamless deployment. My professional repertoire encompasses a wide array of skills: * Backend Frameworks: I have demonstrated proficiency in Go and Rust, along with expertise in Solidity, and Flask. * API Proficiency: I am well-versed in building APIs, be it REST, gRPC, or WebSocket, ensuring seamless communication between software components. * Database Mastery: My expertise extends to working with databases such as MySQL, MongoDB, DynamoDB, and Datastore, facilitating efficient data management. * Messaging Expertise: I have hands-on experience with messaging systems like SQS, SNS, Pub/Sub, Nats, and Kafka, enabling real-time data exchange and event-driven architectures. * Test-Driven Development: I employ best practices in Test-Driven Development (TDD) to ensure the robustness and reliability of code. * Hosting Solutions: My proficiency in cloud platforms such as AWS, GCP, and Azure allows for the seamless deployment and scalability of your projects. Additionally, I am well-versed in orchestration and containerization technologies, including Helm, Kubernetes, and Docker, which enables me to manage your projects comprehensively, from development through to deployment. My unwavering commitment revolves around delivering top-notch, quality-driven solutions to my clients, with a strong emphasis on cultivating enduring, long-term business relationships.

I am a versatile developer with hands-on experience in cybersecurity, software engineering, game development, and AI. I craft clean, scalable code with a focus on performance, security, and maintainability. Whether building systems from scratch or optimizing complex architectures, I adapt fast, think deep, and deliver results.

I’m Sanket Mokashi, a seasoned Senior Software Developer with over 8 years of experience specialising in creating dynamic and scalable web applications. My expertise lies in Rust, Python, Java, React, Node.js, and REST, among other advanced technologies. Starting my freelance journey in 2016, I’ve developed a knack for rapid learning and adapting to new technologies, evidenced by my contributions to significant projects at Amazon Lab126, where I led the India team, and other reputable organisations. In addition to leading teams, mentoring junior engineers, and ensuring the seamless integration of software and hardware interfaces, I have extensive experience in AI-powered development. I implemented a Retrieval-Augmented Generation (RAG) pipeline using Langflow and a custom MCP server to automate EC2 action ticket handling—reducing manual support intervention by 40%. I have also built an LLM-powered chatbot, leveraging Claude 3.5/3.7 with a vector database knowledge repository, serving over 50,000 daily users as an internal knowledge centre. My expertise extends to designing AI-driven automation pipelines for data-intensive workflows and integrating generative AI solutions into enterprise applications. I’ve spearheaded the implementation of event-based architectures, microservices, and cloud-native solutions leveraging AWS services, demonstrating my capability in both technical leadership and hands-on development. Let’s connect to discuss how I can bring your vision to life with my versatile programming skills, deep AI/LLM expertise, and a commitment to delivering innovative, high-impact solutions.

Full-stack engineer with 20+ merged PRs across major open source projects including GitHub CLI, OpenAI Codex, Google ADK, CalCom, and Expensify. I ship production code in TypeScript, React Native, NextJS, Python, and Go. Currently building AI-powered health products at August AI, a health-tech startup with 7M+ users. Previously shipped features across scheduling infrastructure, CLI tooling, and mobile apps. What I bring: deep codebase reading, fast bug isolation, clean minimal fixes. I find existing patterns in the codebase and build on them instead of reinventing. Stack: TypeScript, React Native, NextJS, NodeJS, Python, PostgreSQL, Prisma, tRPC, REST APIs, GitHub Actions.
