You will get a FastAPI or Python backend with Supabase and PostgreSQL
Project details
I'll build your backend API from scratch — clean architecture, proper auth, database design, and all the endpoints your frontend or mobile app needs.
Stack I use: Python + FastAPI for the API layer, Supabase + PostgreSQL for the database with row-level security, and background job scheduling for async tasks. I can add Twilio for SMS/voice, Stripe for payments, or any third-party API integration you need.
I built DebtAgent — a multi-tenant SaaS platform on this exact stack — so I know the edge cases and production gotchas, not just the happy path.

About Bernard
AI Engineer & Full-Stack Developer, Trading Bots and LLM-Powered Apps
Nairobi, Kenya - 8:52 pm local time
━━ AI & LLM ENGINEERING ━━
I build production-ready AI applications using the Anthropic Claude API, OpenAI GPT-4, and open-source models. This includes AI agents, intelligent chatbots, crypto signal bots powered by sentiment analysis (CryptoPanic, news feeds), Telegram distribution pipelines, and multi-platform automation. I handle everything from system prompt engineering to API integration and real-time streaming responses.
━━ BACKEND & SAAS DEVELOPMENT ━━
I architect and ship full-stack SaaS products end-to-end. My current project — DebtAgent — is a multi-tenant automated debt collection platform serving U, USA, Kenya, Nigeria, and Ghana. Stack: Next.js (frontend), Supabase + PostgreSQL (database & auth), Twilio (SMS/voice automation), and Python microservices for scheduling and automation logic. I'm comfortable with REST API design, webhook systems, background jobs, and multi-tenant data isolation.
━━ ALGORITHMIC TRADING BOTS ━━
I've built and deployed multiple live trading systems:
• MQL5 Squeeze Momentum EA on XAUUSD — live on MT5 (Exness), ~41% win rate
• Python BTC/USDT EMA crossover bot — Binance Futures via CCXT
• Liquidation cascade snapback bot — real-time orderbook parsing + Binance Futures API
• Funding rate extreme fade strategy — Python, Binance Futures
• Ben Sniper Pro MQL4 scalper — MT4 live deployment
━━ WHY HIRE ME ━━
✓ I ship working code fast — most EAs in 24–48h, SaaS MVPs in 1–2 weeks
✓ Real backtest receipts and live trading experience, not theory
✓ AI-first mindset — I default to automating and intelligencing everything
✓ Surgical edits — I touch only what needs changing, no unnecessary rewrites
✓ Honest: if your strategy has no edge or your architecture is wrong, I'll say so
Based in Nairobi, Kenya. Open to short-term builds, monthly retainers, and long-term product partnerships.
