KleosVoice  —  real-time AI receptionist for company operations

The constraint — a caller notices silence at roughly one second. Everything below is built around that number.

• Assembled a cascaded STT → LLM → TTS pipeline (Deepgram · Claude/Groq · Cartesia) riding Twilio phone calls, engineered against a sub-800 ms voice-to-voice target end to end.
• Wrote 8 function-calling tools for booking, message-taking, and emergency escalation, behind a code-enforced read-back gate — the model cannot commit a booking it hasn't read back to the caller, so hallucinated confirmations are structurally impossible rather than prompt-discouraged.
• Made the design config-driven for multi-tenant reuse: a new business is a config file, not a fork.
• Added a swappable LLM backend — free Groq for volume, paid Claude for quality — plus Twilio-signature-verified webhooks so the call endpoint can't be spoofed.
• Built a Next.js ops console surfacing calls, transcripts, and per-stage latency for debugging what the caller actually heard.

  Peer-to-Peer Staking Architecture  —  TRON mainnet

Live on mainnet — real TRX, real custody, no testnet asterisk.

• Deployed a custodial TRX pooled-staking vault issuing TRC20 receipt tokens, so a staked position stays liquid and transferable instead of locked.
• Implemented ECDSA off-chain reward authorization with per-user nonces and deadline-bounded signatures — rewards are computed off-chain and settled on-chain without exposing the contract to replay.
• Designed multi-position staking with atomic compound logic that mints fresh GS shares on reinvestment, keeping share accounting exact across concurrent positions.

  FlashTrade  —  algorithmic crypto trading bots

Many bots, one process pool, no cross-talk.

• Architected a full-stack trading platform on React · Node · MongoDB with BullMQ-orchestrated concurrent bot workers, so strategies run isolated and independently restartable.
• Engineered an AI copilot that computes RSI, ATR, and EMA indicators, then auto-generates and launches strategies from them instead of leaving the user to hand-tune parameters.
• Integrated Binance spot & futures REST + WebSocket feeds with AES-encrypted API credentials and JWT auth — user keys are never at rest in plaintext.

  Crux AI  —  résumé to deployed portfolio, in one pass

• Built a modular portfolio generator in React + Tailwind with a set of modern, responsive templates that share one data contract.
• Implemented résumé parsing with Gemini to convert unstructured PDF text into structured JSON, which then feeds any template without per-template glue code.
• Backed it with Express + Prisma + PostgreSQL for durable persistence, secured APIs, and Clerk authentication.
• Ships the finished site to Vercel automatically — the user's input is a PDF, the output is a live URL.
