Solana Blockchain Developer (Data & Analytics Focus) -- 2

@ustymk

Solana Rust Node.js are the technologies I used to build and launch a live Solana data parser [login to view URL] I implemented real time parsing of Solana blocks, optimized account tracking, and integrated statistical analysis pipelines I have been working on Solana and blockchain analytics projects for more than 4 years For your project I would refactor the SOL filter to compute profit holder percentages, track active addresses with flexible timeframes, and implement historical std deviation metrics with efficient indexing Here is a similar Solana project on my GitHub [login to view URL] where I built a parser for Solana on chain data to extract account activity and token behavior Since you emphasized proven Solana blockchain development I confirm my expertise building Solana token filters and data tools that scale alongside ETH BSC and Polygon I am willing to dedicate my skills to deliver a production ready SOL filter upgrade with measurable accuracy and performance Regards, Ustym.

Hi there, I am a Solana-native blockchain developer with hands-on experience building tools that analyze on-chain data, track token behavior, and generate actionable insights. I have previously worked on multi-chain filters and analytics platforms that handled ETH, BSC, Polygon, and Solana, extracting holder metrics, computing statistical measures like standard deviation, and tracking active addresses over time. I can optimize your current Solana filter to efficiently calculate % of holders in profit, historical std. deviation, and changes in active addresses across flexible timeframes. I will ensure your SOL filter matches the level of sophistication you already have on ETH, BSC, BASE, and Polygon while maintaining clean, efficient code. I want to note that the given budget seems low for this depth of work, but I am happy to connect and discuss priorities, realistic scope, and milestones to deliver a high-quality, production-ready solution. Thanks, Rahul A.

Hi, I’ve reviewed your job description and believe I would be an excellent fit for this project. I am an experienced Solana Blockchain developer with strong background in solana data extract and analyse. - Efficiently extract and analyze % of holders in profit In my recent project, I used Helius to extract and created backend which can analyse data from helius. - Be able to compute Std. Deviation calculations and historical std. dev. data You want to go beyond just % holders in profit and also compute things like standard deviation (volatility) on Solana tokens, ideally on a historical basis. In this case, I can use Birdeye API to get historical price volatility std. dev. And can use helius swap history to compute holders’ avg. buy price, then compute std. dev. across holders. - Track changes in active addresses (flexible timeframes) You want to track active addresses on Solana over time, with flexible timeframes (e.g., daily, weekly, monthly). This is also completely available by using Birdeye API and Helius. - Update our current SOL Filter to the latest requirements in general It's depends on your requirements and I would discuss further in private chat. Look forward to hear from you soon. Thanks&Regards, Abdul.

I've successfully delivered similar data analytics solutions on Solana, leveraging Rust and the Solana RPC API for a high-frequency trading firm, achieving sub-millisecond latency. My expertise in on-chain data processing, including account analysis and transaction history retrieval, ensures optimal performance and accuracy. My approach involves refining your existing filter using Rust for optimal performance and integrating it with a robust data pipeline built using Apache Kafka for real-time data streaming and processing. This will enhance data visualization and analysis using tools like Grafana, offering comprehensive insights into market trends and coin behavior. The solution will be designed for scalability and maintainability. Ready to discuss how I can enhance your Solana coin filter to unlock unparalleled market insights? Could you share details about your current filter's architecture and its integration with existing systems so I can tailor a solution precisely to your needs?

Hello, I am excited about the opportunity to work on optimizing and expanding your Solana Filter. With extensive experience in blockchain development and a deep understanding of the Solana ecosystem, I am confident in my ability to meet your requirements and enhance your current codebase. My expertise includes efficiently extracting and analyzing holder profit percentages, computing standard deviation calculations, and tracking active address changes over flexible timeframes. I have previously developed similar functionalities on other chains and am eager to apply the same rigor to your Solana filter, ensuring it meets the latest standards required for optimal performance. Together, we can take your tactical crypto filter to the next level, leveraging data-driven insights to unlock smarter trading signals. I am looking forward to collaborating and driving real impact in achieving your project goals. How do you envision the ideal enhancements for the current Solana filter to align with your overall trading strategy? Thanks, Faisal

Hi, I’m Goran. I can take your Solana filter to the next level by optimizing on-chain data extraction and analytics. I’ll implement accurate profit-holder calculations, build real-time and historical standard deviation metrics, and add flexible active address tracking. The SOL filter will be upgraded to perform as seamlessly as your ETH, BSC, Base, and Polygon systems, ensuring fast and reliable insights without RPC slowdowns. Deliverables include clean, well-documented code and a stable filter that generates actionable trading signals. You’ll get a plug-and-play solution that transforms Solana activity into real alpha for your team.

Hi Karoly A., I recently completed a very similar project. I can show u sample. Questions: - How do you define “holders in profit” on Solana: per-wallet cost basis from on-chain fills (Raydium AMM/CLMM, Orca v1/Whirlpool, Phoenix, Jupiter routes), mints/airdrops/LP burns, and transfers, with FIFO/WAC choice—and should we exclude PDAs (open-orders, staking escrows) and token-2022 extensions? - What infra and freshness do you mandate: custom Geyser plugin + ClickHouse/S3 lakehouse vs Helius/BigTable; backfill depth; finalized vs Jito near-real-time; target QPS for queries and number of tracked mints? Suggestions: - Implement a Solana-native indexer: Geyser streams (+ vote dedupe) and optional Jito mempool; parsers for Raydium/Orca/Phoenix to reconstruct trades and wallet inventories; ATA-normalized balances; slot→time mapping per-epoch; store in ClickHouse with materialized views for 1m/5m/1h; compute Yang–Zhang vol and rolling std dev; PnL marked to Pyth TWAP with DEX fallback. - Active address analytics: unique actors per mint across transfer/swap/CPI to token and token-2022; PDA/MM heuristics filtered; HyperLogLog sketches for flexible windows; handle wrapped SOL and Wormhole mints; expose gRPC/REST for your filter; Rust workers (tokio) + Redis cache for low-latency signals. You send me a message ok, lets discuss and btw my portfolio is uploaded here and on my website. Best Regards, Sid
