SOLANA · TELEGRAM · BACKEND
I build the parts of Solana and Telegram bots most developers underestimate — execution reliability, RPC resilience, custody and payment flows that hold up under real load.
FLAGSHIP CASE STUDY
A production Solana copytrading bot on Telegram — built solo, from zero, in Node.js. Multi-DEX execution, resilient RPC infrastructure, custodial wallets and real payments, all in one system.
01 · EXECUTION
Routing across Raydium, Orca, Meteora and pump.fun bonding curves with a Jupiter fallback. Versioned transactions, congestion-aware priority fees, retry logic and on-chain P&L. Sub-3s pre-graduation buys and ~1.5s AMM fills via an optimistic-submit pipeline fed by a Helius WSS event stream with poll-based fallback.
02 · RPC INFRASTRUCTURE
Multi-provider failover pools across Helius, QuickNode and Chainstack, with per-endpoint rate limiting, circuit breakers and automatic failover. Keeps bots alive and trading when a provider browns out.
03 · WALLETS & CUSTODY
In-app custodial wallets with HD key derivation (BIP-39) and encrypted storage (AES-256-GCM). 2FA/TOTP via Google Authenticator, OTP-gated withdrawals and full audit logging on every sensitive action.
04 · PAYMENTS
Stripe Checkout with verified webhooks alongside native SOL invoicing (pending → detected → confirmed). Referrals, coupons, three-tier subscription billing and idempotent, crash-safe payouts.
BUILT-IN RISK ENGINE

HOW I WORK
We agree exactly what gets built up front. No moving targets, no surprise invoices.
You own the code. Everything is handed over, readable and documented — no black boxes.
If something I built breaks in the first 30 days, I fix it. I stand behind what I ship.
