## Industry Experience

### Rust Backend Engineer — Apeing.ai

**Period:** Nov 2025 - May 2026
**Location:** Miami, USA (Remote)

Rust backend engineer working on real-time trading and indexing pipelines on Solana.

**Highlights:**
- Built a Solana blockchain indexer using Yellowstone gRPC to parse swaps and emit structured trade events in real time.
- Built a real-time, event-driven notification platform by developing a Solana wallet indexer for on-chain token movements (replacing third-party webhooks), streaming events via Redpanda/Kafka, and fan-out processing through Rust workers into idempotent, preference-aware notifications delivered through PostgreSQL-backed in-app WebSocket updates and Firebase push.
- Integrated Privy for wallet/auth flows to improve user onboarding and secure account linking between embedded/external wallets and backend notification/trading systems.
- Built a real-time trading pipeline handling 10k+ trades/sec, generating multi-interval OHLC candles with sub-250ms latency.
- Contributed to a high-throughput event-driven system, building downstream consumers that process asynchronous events and perform batched, idempotent writes to PostgreSQL.
- Architected multi-level caching (in-memory + Redis) and scalable DB access, cutting DB load by 80%+ and API latency to under 50ms.

**Tech:** Rust, Axum, PostgreSQL, Redis, WebSockets, Solana, Yellowstone gRPC, Privy.

## Open Source / Projects

### trade_backend (featured)

**Language:** Rust
**URL:** 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.

**Tags:** Rust, Axum, PostgreSQL, Redis, Redpanda, Solana, Yellowstone gRPC, ClickHouse, WebSockets

### go-distri (featured)

**Language:** Go
**URL:** 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.

**Tags:** Go, Distributed Systems, HashiCorp Raft, libp2p, Kademlia DHT, Peer Discovery, Leader Election, Consensus, TCP, HTTP, Tailscale

### BuilderBrain (featured)

**Language:** JS/TS
**URL:** 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.

**Tags:** TypeScript, Next.js, Express, Coral, GitHub, Notion, OpenRouter, SSE, Node.js

### zKonnect (featured)

**Language:** JS/TS
**URL:** 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).

**Tags:** Next.js, Solana Actions, Anchor, Rust, Prisma, Docker

### invoice_rust

**Language:** Rust
**URL:** 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.

**Tags:** Rust, Axum, PostgreSQL, SQLx, Redpanda, Docker, OpenAPI, Webhooks
