Solo Developer Implementation Roadmap

Solo Developer Implementation Roadmap

Overview

This is a realistic, achievable roadmap for building the Solana trading system as a solo developer. It focuses on incremental delivery, MVP-first approach, and practical milestones.

Key Principles

  1. MVP First - Get a working arbitrage bot before adding complexity
  2. Iterative Development - Each phase delivers working software
  3. Leverage Existing Code - Reuse patterns from prototypes extensively
  4. Start Simple - Begin with TypeScript only, add Go/Rust later
  5. Local First - Deploy to cloud only when needed

Time Commitment

  • Part-time (20hrs/week): ~8-10 months to production
  • Full-time (40hrs/week): ~4-5 months to production

What NOT to Do

❌ Don’t:

  • Build a complex microservice architecture upfront
  • Implement all strategies at once
  • Deploy to Kubernetes (overkill for solo project)
  • Build a complex web UI (use Grafana dashboards)
  • Optimize prematurely (get it working first)
  • Trade with large amounts until proven

βœ… Do:

  • Start with one strategy (arbitrage)
  • Use existing code from prototypes
  • Deploy with Docker Compose initially
  • Focus on reliability over features
  • Test extensively with small amounts
  • Celebrate small wins

Milestones to Celebrate πŸŽ‰

  1. First successful RPC call (Week 1)
  2. Quote service responding (Week 2)
  3. First opportunity detected (Week 3)
  4. First trade executed (Week 4) ← BIG ONE
  5. 7 days without crashes (Week 6)
  6. First profitable grid cycle (Week 11)
  7. Deployed to production (Week 13)
  8. 1 month in production (Week 17)

Next Steps

  1. Review this roadmap and adjust timelines based on your availability
  2. Set up the repository structure (Phase 0)
  3. Start with Week 1 tasks
  4. Track progress using GitHub Projects or similar
  5. Document decisions and learnings in /docs/decisions/
  6. Join Solana Discord for help when stuck
  7. Keep a trading journal to track performance

Remember: This is a marathon, not a sprint. Take breaks, learn continuously, and enjoy the journey! πŸš€
