Hire the Best CURL Developers in Dhaka, BD

I fix the technical side of email and WordPress — the parts that break quietly and cost you customers before anyone notices. Most recently: a client's campaigns were landing in Gmail spam across three sending domains. Authentication was already correct, so I diagnosed it as domain reputation instead, ran a staged recovery, and brought every domain to a 0% spam rate on Google Postmaster Tools — where they've stayed. WHAT I DO Email deliverability & infrastructure Multi-domain sending setups, mailbox pools, SPF/DKIM/DMARC, warm-up scheduling, volume ramping, reputation monitoring, and inbox placement testing across Gmail, Outlook and Yahoo. I diagnose why mail isn't landing rather than guessing at it. WordPress & Elementor engineering Custom PHP, must-use plugins, rewrite rules, REST endpoints, ACF-driven dynamic templates, and form-to-API webhooks with proper logging. I work on the problems plugins can't solve — plugin conflicts, broken integrations, layouts that collapse on mobile, sites that stopped working after an update. Full-stack development PHP, Python, MySQL, JavaScript. I built and launched ValidateTime, my own email verification SaaS — SMTP validation engine, job queue, credit billing through Paddle and crypto, affiliate system, and admin panel. Solo, end to end. HOW I WORK I diagnose before I quote. If I don't know the cause yet, I say so rather than promising a fix I can't guarantee. I log everything. When I build an integration, every request and response gets written to a log — so if something fails, you find out in minutes, not next quarter. That habit has caught silent submission failures that would otherwise have been lost leads. I tell you when scope changes. If a job turns out bigger than expected, you hear it before I do the work, not after. I document what I built. You get a written handover, not a black box only I can maintain. BACKGROUND Self-taught, started coding in 2023, now working full-time with long-term clients on production systems handling real customer data and real money. I care more about things working reliably than about looking clever. If you're dealing with emails going to spam, a WordPress site behaving strangely, or an integration that silently drops data — send me the details and I'll tell you what I think is happening before you commit to anything.

I build and troubleshoot AI assistants, automation workflows and full-stack applications. I connect your tools, develop the missing backend or interface, and help deploy and monitor the system with appropriate security controls. You can bring a new project, a workflow that still needs manual coordination, or an existing application that is failing. We start by defining the problem, the expected result and a useful first milestone. WHAT I CAN HELP WITH • AI & automation: Knowledge assistants using retrieval-augmented generation (RAG), n8n workflows, API integrations, lead follow-up, content approval and structured AI output. I combine existing tools with custom code where the workflow needs it. • Full-stack development: Client portals, dashboards, web applications and WordPress/Shopify integrations. Frontend interfaces, backend services, databases and background jobs are scoped around how your team will use the system. • Cloud & monitoring: Container deployment, CI/CD and deployment troubleshooting. Monitoring scope can include health checks, logs, metrics and alerts, with the required checks and notification paths verified during delivery. • Security & incident response: WordPress malware investigation and containment, access-control improvements and application security checks. Changes are scoped around backups, disaster recovery, rollback and verification; a clean scan alone is not a guarantee of safety. RELEVANT PROJECT WORK • Agency content platform: Connected a media library, AI copy generation, client feedback, internal approval and controlled asset delivery. Clients review campaigns through a portal; approved assets are handed over for manual publishing. • Lead follow-up automation: Connected JotForm, n8n, Google Sheets and Twilio for site-specific lead routing, welcome messages and scheduled follow-ups, with recorded send outcomes. • WordPress automation: Built a PHP/Python workflow that matches pages and posts, generates and validates SEO metadata, updates AIOSEO and reports results through background jobs. • RAG assistant improvement: Corrected a memory issue that could treat an assistant's earlier answer as a fact supplied by the user. The revised handling separates user-authored content from generated responses and excludes legacy mixed records. • WordPress incident containment: Investigated recurring malicious code, quarantined confirmed artifacts with backups, and checked for recurrence after real page requests. Containment findings and remaining recovery work were reported separately. TOOLS I WORK WITH • AI, automation & agentic coding: Claude Code, Codex, MCP, n8n, OpenAI API, Claude API, Pinecone and LightRAG. • Frontend & backend: JavaScript, TypeScript, React, Next.js, Tailwind CSS, Python, FastAPI, Flask, Node.js, Express, PHP and REST APIs. • Commerce & CMS: Shopify, Liquid, WordPress, WooCommerce, Contentful and Stripe. • Databases: PostgreSQL, Supabase, MongoDB, Redis, SQLite and DynamoDB. • Cloud & DevOps: AWS, Google Cloud, Azure, Docker, Kubernetes, Terraform, GitHub Actions, Linux and Nginx. • Monitoring & security: Prometheus, Grafana, Loki, Jaeger, Prowler, Checkov, Trivy, OWASP ZAP, SonarQube, Gitleaks, Semgrep and Bandit. • Business integrations: Twilio, JotForm, Google Sheets, Google Drive and webhooks. I choose the tools around your existing system, budget and maintenance needs. HOW I WORK WITH YOU 1. I review your current system, access requirements and expected behavior. 2. You and I agree on scope, acceptance checks and the first milestone. 3. I implement and test the agreed workflow, including relevant failure cases. 4. I hand over the implementation, configuration guidance and documentation, with any remaining limitations stated clearly. My earlier work as a Physiotherapy Technologist gives me additional context for healthcare and wellness projects. Send me the tools you use, what you want built or fixed, and what a successful result would look like. We can define the first milestone from there. I do not accept projects involving interest-based finance (Riba), conventional insurance, gambling, adult content, or any Haram activity.

Founders and teams usually come to me when a manual process has grown too large, a scraper keeps breaking, or several tools need to work together without someone watching them all day. I build AI automation, web scraping systems, agents, APIs, and data pipelines. The goal is simple: remove repetitive work and leave you with something your team can understand, run, and maintain. ✓ 100% Job Success ✓ Top Rated ✓ 70 Upwork jobs and 1,282 hours ✓ 5+ years in automation, scraping, APIs, and backend systems Some of my work is public. StealthPlex is my multi-engine Python project for moving between direct HTTP requests and browser automation. I maintain Google News URL Decoder and Facebook Pages Scraper. I also built DockLift for deploying and managing Docker applications. My client work includes multi-source product and supplier search for RBEX and ProcurX. ● AI Automation & Agents → Agents that call APIs, tools, databases, and business systems → Multi-step workflows with structured output and validation → AI-assisted data extraction, classification, matching, and routing → Bots and internal assistants connected to live information → Fallback logic and human approval when a wrong answer matters → Scheduled and event-driven workflows using APIs and webhooks I do not treat an API call with a long prompt as a finished agent. I build the surrounding workflow that gives it context, checks the result, handles failure, and passes the output to the right system. ● Web Scraping & Browser Automation → Dynamic and JavaScript-heavy websites → Protected targets that need sessions, proxies, or browser fallback → Playwright, SeleniumBase, Scrapy, curl_cffi, Scrapling, and Apify → Pagination, authentication, retries, checkpoints, and interrupted-run recovery → Product, directory, supplier, review, news, and structured business data → Delivery to CSV, Excel, JSON, Google Sheets, APIs, or databases → Existing scraper repair, maintenance, and performance debugging I test difficult websites before promising a full extraction. Some targets only need clean HTTP requests. Others need a real browser or a different collection plan. I would rather prove that early than sell you a confident guess. ● APIs & Backend Automation → FastAPI and Python backend services → REST APIs, webhooks, authentication, and third-party integrations → PostgreSQL, Redis, data storage, and background processing → Telegram, Discord, notification, and workflow bots → Data validation, normalization, deduplication, and matching → JavaScript or TypeScript services when they suit the existing stack ● Multi-Source Data Workflows → Collecting results from several websites or APIs → Converting different source formats into one consistent structure → Duplicate detection and source-level error tracking → Scheduled refreshes and change detection → Search, comparison, and supplier or product matching workflows → Clear output that can be reviewed before it reaches production This is the kind of work behind RBEX and ProcurX, where information from different sources has to become one useful workflow rather than a folder full of unrelated files. ● Deployment & Reliability → Docker and Linux deployment → Logs, retries, rate-limit handling, and failure alerts → Environment configuration and secrets handling → Monitoring, restart behavior, and run documentation → Clean handover so the system does not depend on my laptop ● How I Work → Understand the current process and where it fails → Test the riskiest assumption with a representative sample → Agree on the smallest useful milestone → Build the complete workflow after the approach is proven → Keep progress and technical tradeoffs clear → Deliver code, setup instructions, and documentation ● Best Fit → You want to replace repetitive manual work → Your scraper works sometimes but cannot be trusted → You need an AI agent connected to real tools and data → Several APIs, websites, spreadsheets, databases, or bots need to work together → You need the backend and deployment, not only a quick demo → You want honest feasibility advice before committing to a full build Send me the process, website, or API you want to automate and tell me where it currently breaks. I will review the difficult part first and tell you whether it needs a focused fix, a rebuild, or a short paid feasibility test.
