I’m a Computer Science graduate with a strong foundation in software development, system security, and automation, together with a growing focus on research-driven creative strategy for digital products and ads.
On the technical side, I’ve delivered multiple full-stack projects using the MERN stack, and I’m proficient in Python, C, C++, SQL, Linux, and Bash. I’ve also worked on software–hardware integration within a SCADA control system, where reliability, clarity, and system thinking are critical.
Beyond development, I bring a business-oriented mindset to every project. I understand that software, products, and ads don’t exist in isolation- they serve a market, a user, and a goal.
-----
Creative & Strategy Experience
I have hands-on experience assisting in creative strategy and ad scripting, where my role focused on:
Understanding the target audience and market positioning
Researching user psychology, pain points, and buying intent
Translating product features into clear, factual, and appealing narratives
Helping shape ad scripts tailored to specific demographics and use cases
This isn’t guesswork or “creative vibes”, it’s structured research, logical positioning, and messaging that makes sense for the business and the customer.
-----
How I Add Value
Strong analytical and systems thinking
Research-first approach to content and strategy
Ability to bridge technical depth with market understanding
Clear communication without hype or fluff
If you’re looking for someone who can build systems, understand users, and think strategically about how products are presented, I’d be glad to help.

I build and run managed website chatbots for SMBs — a “done-for-you” AI front desk that answers FAQs, guides visitors, captures leads, and hands off edge cases to a human.
Typical setup includes:
• FAQ/Q&A based on approved website content
• Website navigation & service/support flows
• Lead capture & qualification (structured fields)
• Appointment booking integration
• Email handoff + clear fallback rules/guardrails
• GDPR-oriented setup with EU hosting (when required)
Tech stack: Flowise, Azure OpenAI (GPT), n8n, API integrations, automation workflows. I test, deploy, and monitor the bot so you get reliable results without babysitting.

🎮😉Some developers fear SOC2, GDPR, HIPAA ISO 27001… I just treat them like extra requirements in a very strict but fair game. 7+ years and 110+ products
🚀 +65% faster feature delivery
🛡️ 100% regulatory compliance
📉 -60% compliance risks
⚡ +50% faster audit preparation
I learned this early in my career when I realized that being a full stack developer who simply connects frontend to backend is not enough. Real value starts when you become a Compliant Developer, an Information Security Consultation who understands that every line of code can eventually be reviewed by auditors, regulators, or enterprise security teams.
That is why I work as a Compliant Developer, Compliance consultant and full stack developer web developer, building systems where engineering and compliance are designed together from the very beginning. I don’t treat regulation as documentation work added at the end. I treat it as architecture.
My approach combines full stack developer responsibilities with deep focus on information security and regulatory alignment. I build systems that are not only functional but also defensible, auditable, and enterprise-ready.
In my work as a ISC and Compliant Developer, virtual CISO (vCISO) and senior full stack developer web developer, I design end-to-end systems including frontend interfaces, backend services, APIs, databases, and cloud infrastructure. But every technical decision is made with compliance in mind.
I specialize in building systems aligned with key regulatory and security frameworks such as HIPAA compliance, GDPR, ISO 27001, SOC2, ADA compliance, and FDA.
For healthcare and sensitive data platforms, I ensure HIPAA-compliant is embedded into data flows, access control, and encryption strategies. For global products, I design systems aligned with GDPR and gdpr requirements, considering privacy rules, data retention, and user rights in every feature.
For enterprise SaaS platforms, I focus on SOC2 readiness, soc2 audit preparation, soc2 consultant expectations, and long-term soc2 auditor requirements. This includes logging, monitoring, access management, and incident response readiness.
For security-driven organizations, I work with ISO 27001 standards, isms implementation, ISO 27001 certification goals, and collaboration with ISO 27001 auditor and it auditor processes to ensure information security management is structurally sound.
For public-facing digital products, I implement ADA compliance and ada website compliance principles to ensure accessibility for all users, including assistive technology support and inclusive UI patterns.
For regulated industries like healthcare technology and medical software, I also consider FDA requirements, working in contexts where fda consultant expectations and fda medical device constraints define how systems must behave.
My technical stack as a full stack developer includes React, Node.js, TypeScript, Python, APIs, cloud infrastructure, and scalable database design, RAG architectures, and AI agents for AI-powered systems. But what differentiates me as a compliance developer is how I embed auditability, traceability, and security controls directly into the architecture rather than treating them as external constraints.
While Next.js, Supabase, and Shopify are not my primary stack, I have practical experience working with them in production projects, including MVP development, multi-tenant architectures, and Stripe payment integrations.
I often collaborate with stakeholders who think like soc2 consultant roles, ISO 27001 auditor perspectives, gdpr lawyer considerations, and information security teams. My role is to translate these requirements into real system design: authentication flows, role-based access control, audit logs, encryption models, and secure deployment pipelines.
I also help teams validate ideas through MVP development, LLM API, design scalable multi-tenant SaaS architectures, and implement secure Stripe payment flows for subscriptions and billing.
Most developers build features. I build systems that survive audits, compliance reviews, and enterprise procurement requirements. That means thinking like a full-stack developer web developer, but also like an IT auditor who understands what can and will be questioned later.
Over time, I have worked on systems requiring HIPAA, ISO27001, Compliant Developer, GDPR, ISO 27001 certification alignment, SOC2 audit readiness, ADA compliance enforcement, AWS Lambda and FDA constraints. Each of these adds layers of responsibility that affect architecture, not just implementation.
I approach every project as both a full stack developer and a compliance developer.
If you need a full stack developer, Full Stack AI Engineer, AI Integration, HIPAA Compliance consultant, wordpress developer, WordPress Website Developer, web developer, Compliant Developer.
Reduce audit preparation time by up to 50%.
Reduce engineering rework by up to 60%.
Shorten security review cycles by 30–50%.

🏆 Expert-Vetted - Top 1% on Upwork ✅ Top Rated Plus | 100% Job Success ⚙️ 6+ Years in Production AI & Data Engineering
I'm Atique, an AI and Data Engineer who builds LLM systems on top of infrastructure I design and run myself.
Most AI projects don't fail on model choice. They fail on the data underneath: documents that won't parse, pipelines that break under real volume, retrieval that can't cite its source. That's the half most AI freelancers hand back to you. It's the half I specialize in.
I currently lead the data platform at a Berlin fintech, running Redshift, dbt and Dagster in production for a full analytics team, while delivering AI engagements in legal tech, IT operations, and e-commerce.
⚡ Core Services & Expertise
🔹 RAG & Retrieval Systems Hybrid semantic and keyword search, document and knowledge-base Q&A, answers grounded in source text with page-level citations, vector store architecture, retrieval evaluation.
🔹 AI Agents & Agentic Workflows Autonomous multi-agent systems with tool use, defined escalation paths to humans, and state-machine-backed flows rather than one large prompt. CrewAI, LangGraph, LiteLLM.
🔹 Document AI & OCR PDF and scanned document ingestion, structured extraction into typed schemas, multilingual and non-Latin script handling, entity and timeline extraction, chat over document sets.
🔹 AI Automation n8n, Zapier and Make workflows, plus custom Python orchestration. API and systems integration, manual-work elimination, delivered with SOPs and documentation.
🔹 Production Data Engineering Warehouse design and delivery on Redshift and BigQuery, dbt modelling, Dagster orchestration, zero-ETL and DMS migrations, RBAC, cost and query optimization. The layer that makes AI features reliable instead of demo-only.
🔹 Natural-Language Analytics MCP servers and text-to-SQL over live warehouses, so business teams query data in plain English instead of filing ticket requests.
📌 Selected Work
Legal case document platform: court PDF ingestion, extraction of parties and event chronologies, and grounded chat over full case files with source citations.
Autonomous IT incident response platform: agents that triage, diagnose and escalate on defined conditions. CrewAI, LangGraph, LiteLLM.
MCP server over a production Redshift warehouse, now used daily by a data team in place of writing SQL.
Invoice processing automation across BILL API, vision-model extraction, Gmail, Drive, Asana and Sheets.
Production Redshift platform with dbt and Dagster serving analysts and data scientists, including zero-ETL integration and live incident recovery.
Forecasting and optimization systems in energy: IoT battery control with model predictive control, PV production forecasting, electricity price forecasting.
🛠️ Tech Stack
LLMs & Agents: Claude, GPT, open-source models, LangChain, LlamaIndex, LangGraph, CrewAI, LiteLLM, MCP RAG Stack: Vector databases, hybrid retrieval, embeddings, chunking strategies, citation grounding LLM Ops: Prompt engineering, structured outputs, evaluation harnesses, guardrails, refusal handling Dev & Infra: Python, FastAPI, Streamlit, Docker, CI/CD Data Pipelines: SQL, dbt, Dagster, Airflow, Redshift, BigQuery, Postgres, MySQL Cloud: AWS (Redshift, S3, Batch, ECS, DMS, Textract, Lambda), GCP (BigQuery, Cloud SQL) Automation: n8n, Zapier, Make
🤝 How I Work
I scope before I build, and I tell you when a brief is underpriced or a requirement won't survive real data.
Out of scope goes in writing, so it isn't an argument at invoice time.
Acceptance criteria are numbers, not adjectives.
End to end: scoping, build, deployment, documentation, handover.
If your project is mostly a prompt, you don't need me. If it involves real documents, real data volumes, or a system that has to keep running after handover, that's the work I do.
Click "Message" and tell me what you're building.
