Project Overview:
I'm looking for an experienced Golang developer to finalize, polish, and maintain a Telegram Bot connected to a PostgreSQL database.
The project is already in an advanced stage: the core backend is largely written, and the functionality to send SMS via external APIs is implemented and working.

What needs to be done:
The primary goal is to turn the current MVP into a scalable, user-friendly product. We need a developer who can handle API integrations and complex bot logic.

Key Responsibilities:

Dynamic Bot Instance Creation (Multi-tenancy):
Implementation of a flow where the user is asked to input their own BotFather API Key at the start.
The system must then dynamically generate/handle a custom bot instance for that specific client using their token. This is a crucial SaaS-like feature.
UI/UX & Conversational Flow:
Improve the current user interaction. Since this is a Telegram bot, "UI/UX" refers to optimizing the command menus, using Inline Keyboards effectively, and ensuring a smooth, logical conversational flow for the user.
Voice/Call API Integration:
While SMS is ready, we need to finalize or refine the logic for making automated calls via API.
Refactoring & Maintenance:
Clean up existing code if necessary and prepare the architecture for long-term scalability.
Requirements:

Strong proficiency in Golang.
Deep understanding of Telegram Bot API (dealing with webhooks, updates, and custom keyboards).
Experience with PostgreSQL.
Experience consuming third-party REST APIs (specifically for SMS/Voice providers).
Proactive mindset: I'm are looking for someone who takes ownership of the project, suggests improvements, and has a "can-do" attitude.

Availability: I'm looking for a long-term partner available for future maintenance and feature updates.

To Apply:
Please briefly describe your experience with Golang bots and mention if you have ever built a system where users provide their own Bot tokens (dynamic instances)

# Crypto Arbitrage Backend – Project Brief

## 1. Project Scope

Build the backend for a **non‑custodial crypto arbitrage platform** that:

- Manages users (registration, login, JWT auth, 2FA, referral system, basic KYC).
- Integrates with exchanges using **sub-accounts** (e.g., OKX / Binance).
- Monitors balances and deposits in near real time.
- Runs an **arbitrage engine** to:
- Detect opportunities between two exchanges.
- Execute atomic BUY/SELL legs on user sub-accounts.
- Maintains a **trade ledger** with profits, fees, commissions, and basic reporting.
- Exposes APIs for web/mobile clients (REST via gRPC-Gateway).

**Non-custodial guarantee:**
User funds always remain on exchange sub-accounts. The platform never holds private keys and only uses encrypted API keys with limited permissions.

---

## 2. Preferred Tech Stack

### 2.1 Backend (Go)

- **Language:** Go 1.21+
- **RPC:** gRPC
- **API Gateway:** gRPC-Gateway (REST ↔ gRPC)
- **Message Broker:** Apache Kafka (events for balances, trades, auditing)
- **Database:** PostgreSQL (monetary values stored as `DECIMAL`, not `float64`)
- **Cache / Sessions / Rate limiting:** Redis
- **Logging:** `uber-go/zap` (via a shared `pkg/logger` package; no `fmt.Println` in production)
- **Financial Math:** `shopspring/decimal` (to avoid floating‑point precision errors)
- **Configuration:** Centralized `internal/config` module (no scattered `os.Getenv` calls)
- **Architecture:** Strict **Repository Pattern** (handlers use interfaces; no direct DB access)
- **Testing:** Go test + `testify` (unit and integration tests)

---

### 2.2 Python Services (Optional – LLM/Analytics)

If the freelancer also works on Python microservices:

- **Language:** Python 3.11+
- **Web Framework:** FastAPI (async)
- **Financial Math:** Built‑in `decimal` module for all money calculations
- **Shared Modules (no duplication):**
- `config` (central configuration loader)
- `logger` (structured logging)
- `redis` (shared Redis client)
- **LLM Orchestration (optional):** `eino` or similar for multi‑agent workflows

---

### 2.3 Mobile (Flutter) – Optional Context

If the freelancer also touches the mobile app:

- **Language / Framework:** Dart 3+ / Flutter 3+
- **State Management:** Riverpod (or similar)
- **Financial Math:** `decimal` package for all monetary values
- **Architecture:**
- Centralized configuration (no hard‑coded URLs spread in the codebase)
- Centralized error handling (map technical errors → user‑friendly messages)

---

## 3. Deliverables (High Level)

- Backend services in Go, following the stack and patterns above.
- Non‑custodial integration with at least 1–2 exchanges (sub‑accounts).
- Arbitrage engine (detection + atomic execution).
- Database schema (PostgreSQL) with precise monetary types.
- Basic documentation (README, setup instructions, and API description).

I’m upgrading my platform to process transactions through a dedicated blockchain gateway so every payment that passes through the system is cryptographically verifiable and tamper-proof. The job covers designing the gateway architecture, selecting an appropriate chain (Ethereum, Polygon, BSC or another you can justify), building or customising smart-contract code if that proves to be the simplest route, and exposing clean REST/JSON or Web3 interfaces my front-end can call.

The core success metric is end-to-end security: a user initiates a payment on the site, the request reaches the gateway, the transaction is written on-chain, and I receive an instantly checkable hash I can surface back to the user. Performance must remain within normal web-app latency, and the code needs to be clean enough for a future audit.

When you reply, focus on the secure-transaction gateways you’ve built or maintained, any chains or libraries you know inside out (web3.js, ethers.js, Hardhat, Truffle, Solidity, Golang, Rust, Hyperledger Fabric, etc.), and the challenges you solved around confirmations, gas optimisation, or key management. A concise outline of how you would approach this build will help me see whether your experience aligns with the project.

Deliverables
• Technical design and chain selection rationale
• Smart contract or ledger code (if used) with tests
• Gateway/API implementation ready for staging
• Deployment scripts and step-by-step documentation

I’m ready to start as soon as I find the right fit.

We are seeking a Full Stack Software Developer with experience in both Go and PHP/Laravel to join our fully remote team. The successful candidate will take on the critical task of updating and improving our main company website, a production system built in Go and complemented by PHP/Laravel components.

The project is already underway. Core designs and assets are in place, and the work focuses on bug fixes, quality-of-life improvements, and ongoing enhancements rather than a full redesign. Much of the HTML, which was previously embedded directly in Go as strings, has been migrated to Go HTML template files, and the developer will be expected to work confidently within this hybrid, evolving codebase.

This role is ideal for someone who enjoys maintaining and improving mature systems while contributing to a mission centered on literature, knowledge sharing, and digital preservation.

This is an ongoing project requiring 20-40 hours/week.

Key Responsibilities
-Update and enhance Forgotten Books’ main website, ensuring stability, performance, and consistency with existing designs and assets.
-Work with Go and the Go HTML template engine to deliver efficient, maintainable server-rendered pages.
-Contribute to and maintain PHP/Laravel-based components, including backend logic and integrations where applicable.
-Troubleshoot, debug, and optimise existing functionality across the full stack.
-Ensure responsive behaviour and cross-browser compatibility.
-Collaborate with the development team through code reviews, technical discussions, and iterative improvements.
-Integrate additional features and third-party services as required, including potential use of jQuery and the Braintree Payment SDK.

Essential Skills
-Strong professional experience with Go and the Go HTML template engine.
-Professional experience with PHP and Laravel in production environments.
-Solid proficiency in HTML, CSS, JavaScript, and SQL.
-Experience using Git in collaborative workflows.
-Experience working with responsive layouts and cross-browser compatibility.
-Strong analytical, debugging, and problem-solving skills.
-Ability to work effectively within an existing codebase and contribute to code reviews.

Nice to Have
-Experience with jQuery.
-Experience integrating payment providers such as Braintree.
-Experience using Docker in development or deployment workflows.

Qualifications
-Proven experience as a Full Stack Developer, with meaningful production experience in Go and PHP/Laravel.
-A portfolio or examples of prior work demonstrating relevant web applications, particularly those involving Go, Laravel, or similar technologies.

Application Guidelines
Please submit your resume, cover letter, and any relevant project portfolio. Your application should clearly highlight your experience with Go, PHP/Laravel, and any additional skills that make you a strong fit for this role such as HTML, CSS, JavaScript, SQL.
