# Manish Saha

> Software Engineer based in Bangalore, India. From protocol to pixel, I engineer production-grade, high-throughput systems built to scale under fire — shipped at startup speed, with zero patience for bad UX.

Open to impactful projects and product-focused engineering roles.

## Projects

- [trade_backend](https://github.com/Manice18/trade_backend): Rust monorepo for a Solana-native trading platform: launchpad and Jupiter swaps, real-time OHLC and market data over WebSockets, event-driven order flow via Redpanda, Yellowstone gRPC indexers, and ClickHouse-backed chart analytics. Impact: End-to-end trading stack with split API runtime roles, idempotent event consumers, and multi-level caching for high-throughput workloads.
- [go-distri](https://github.com/Manice18/go-distri): A highly available distributed key-value store built to explore real-world distributed systems concepts. Uses a hybrid peer discovery model (central registry + libp2p/Kademlia DHT), a custom libp2p handshake to exchange cluster metadata, and HashiCorp Raft for leader election and replicated state. Supports cross-network clusters using Tailscale to advertise dialable addresses across NAT. Impact: Demonstrates distributed systems concepts including hybrid peer discovery, libp2p networking, Raft consensus, and NAT traversal, showing how nodes discover each other, elect a leader, and maintain consistent replicated state across machines.
- [BuilderBrain](https://github.com/Manice18/builder_brain): Personal project memory assistant that connects GitHub (what you code) with Notion (what you plan). Answers natural-language questions by querying live data through Coral SQL, then optionally narrates results with an LLM — Coral is the source of truth, not the model. Impact: Coral-first read-only architecture with rule-based intent routing and fixed SQL templates (no LLM-generated queries), plus cross-source GitHub↔Notion joins for abandoned-project detection and repo↔ideas-page matching.
- [zKonnect](https://github.com/zKonnect/zkonnect-common): Token-gated event hosting platform on Solana enabling creators to share event links via Blinks. Integrated Reclaim Protocol for zk-proof creator verification and Huddle01 for dRTC token-gated rooms. Impact: Winner at Solana Radar Hackathon (Reclaim Protocol track).
- [invoice_rust](https://github.com/Manice18/invoice_be): Rust workspace for a multi-tenant invoicing and payments API: customer and invoice management, mock PSP card charges with idempotency keys, invoice state machine, payment reconciliation workers for async and ambiguous PSP outcomes, and signed webhook delivery over Redpanda with exponential backoff. Impact: Payment-correctness design with row-level locking, idempotent pay flows, and a reconciliation worker for timeout and network-error edge cases—modeled after production PSP integration patterns.

## Highlights

- Built real-time Solana indexers, trading pipelines, and notification systems (10k+ trades/sec, sub-250ms OHLC, event-driven architecture).
- Designed and scaled event-driven systems using Kafka/Redpanda with idempotent consumers and high-throughput processing.
- Reduced DB load 80%+ and API latency to <50ms via caching + batched idempotent writes.
- Shipped Solana/SVM products end-to-end (Anchor + Next.js + Web3 integrations).
- Improved web performance (e.g., 60% faster loads) with image optimization and refactors.
- Delivered complex UIs and workflows with React/TypeScript and modern state/tooling.

## Achievements

- 1st place - Solana Radar Hackathon (Reclaim Protocol side-track).
- Winner of 3 Solana bounties on Superteam Earn (Solana track).
- Winner - Hack4Bengal 2.0 (Solana track).
- 3rd place - Talent Olympics (Escrow UI + Blink track).
- Mentored and judged multiple web2 & web3 hackathons; active SuperteamIN member (Aug 2023 - Jan 2026).
