This is a part-time, remote, contract role for a Freelance Web Developer. You will build and maintain client websites in Webflow and WordPress, including full site builds, service and industry pages, landing pages, case study templates, and CMS work, supporting our clients' goals across multiple accounts. You will turn designs into responsive, fast-loading pages, wire up integrations and tracking, and collaborate with our creative and marketing teams on builds that connect to real campaign goals.

This is a largely async role. You will mostly work on your own schedule, so we want someone serious and capable who shows up reliably, manages their own work, and brings a strong point of view on what makes a site fast, clean, and built to last. We care about work that performs in the real world, not builds that look fine in the preview and fall apart on a phone.

This is also not a drag-and-drop, template-and-pray role. We expect you to use AI fluently as a tool, but the build has to be solid, the code clean, and the structure intentional. If your sites are bloated, slow, or held together with workarounds you can't explain, this is not the fit.

What you'll do - Build and maintain Webflow and WordPress sites that are responsive, fast, and structured properly, from full builds to landing pages, service pages, and CMS work. - Turn Figma designs into pixel-accurate, mobile-first pages that look as good on a phone as they do on desktop. - Wire up integrations and tracking, including HubSpot forms, GA4, and Google Tag Manager, so every site captures and measures what it should. - Manage builds across several client accounts at once, switching platform, context, and brand cleanly between them. - Handle the technical housekeeping that keeps a site healthy, including page speed, accessibility, schema, and clean URL structure. - Drop into custom HTML, CSS, and light JavaScript, plus PHP on the WordPress side, when the platform alone won't get it done, and hit deadlines without hand-holding.

Qualifications - Strong, demonstrable skills in both Webflow and WordPress, including CMS collections in Webflow and custom themes or page builders in WordPress - Solid HTML and CSS, with the ability to write custom code, plus comfort with light PHP for WordPress work - A real understanding of responsive design, performance, and accessibility, not just making it look right on your own screen - Fluency with AI dev tools as an accelerator, paired with the judgment to ship clean, intentional builds rather than bloated ones - Exceptional communication skills and the ability to take a brief and run with it - Experience connecting websites to marketing tools and tracking, ideally HubSpot, GA4, and Google Tag Manager - Familiarity with technical SEO basics such as schema, slugs, and Core Web Vitals - Meticulous attention to detail and a habit of QA-ing your own work to a publish-ready standard - Ability to work independently and meet deadlines in a fast-paced, largely async environment - Previous experience at a marketing agency or building client-facing sites is a plus - Bachelor's degree in Computer Science, Web Development, Design, or a related field preferred, or equivalent portfolio and experience

How We Work We run weekly sprints, plan in Notion, talk in Slack, and keep meetings to a minimum. You'll get clear briefs and the room to do the work without being micromanaged. We pay fairly and on time, and we treat contractors like part of the team. Details - Contract / freelance, remote, part-time, largely async - Ongoing work with steady volume across accounts - Rate [$XX]/hr or per-project, to be discussed

Location: Prague, Czech Republic (on-site)

appflame — Ukrainian product-driven tech company building world-class products: Hily, Taimi, AdConnect, Mailkeeper, and more.

About us:

• 7 years in the market, 500+ team members, offices in Kyiv, London, Limassol, and a co-working hub in Warsaw.
• In 2025, appflame ranked 5th among the top 50 employers in Ukraine according to Forbes and won the “Best Place for Growth” award.
• Our apps Hily and Taimi are among the top 5 dating apps in the US with over 70 million users. AdConnect and Mailkeeper focus on building proprietary B2B and B2C solutions.

Our mission:

• To put Ukrainian-built products on the global map.

Our goals:

• Break into the global top 5 product companies.

• Make Ukraine a country where unicorns are born.

We’re looking for bold, driven people who are passionate about building real products and dream of launching and scaling great startups. You bring the ambition — we provide the environment to make it happen.
 

What you’ll do:

• Design and develop an AI-powered productivity analytics platform — from data pipeline architecture to the final analytical product that helps teams make data-driven decisions.
• Build scalable LLM pipelines (Claude, GPT): develop data chunking strategies, implement MapReduce approaches for parallel processing of large datasets, and synthesize results into structured reports and insights.
• Create a meta-workflow system where LLMs generate, test, and deploy automation scripts in an isolated environment — with automatic self-correction loops and production deployment without manual intervention.
• Develop system-level prompt engineering: build and maintain a library of prompt templates for various analytical scenarios — from summaries and profiles to deep performance analysis.
• Build an evaluation framework for AI output quality control: hallucination detection, consistency scoring, regression tests — ensuring the product delivers reliable and reproducible results.
• Scale the platform to new domains and analysis types without linear growth in manual effort — through an architecture that allows adding new modules via configuration, not code.
• Document AI architecture, define automation specs, and present product insights to stakeholders and clients.
   

It’s a match if you have:

• 2+ years of experience working with LLMs in production: prompt engineering, pipeline development, API integration — with at least 1 year of hands-on experience with advanced features (tool use, structured outputs, agents).
• Strong Python skills (async, dataclasses, type hints, API integrations) and a commitment to writing clean, testable, and maintainable code.
• Understanding of MapReduce patterns for LLM processing: ability to choose chunking strategies, organize parallel processing, and aggregate results into a cohesive analytical product.
• Experience building agentic systems: tool use, self-correcting loops, multi-agent workflows — and the judgment to know when an agent works better than a rigid pipeline.
• Proficiency in SQL and experience working with analytical databases.
• English at C1 level — comfortable reading documentation, writing technical specs, and communicating asynchronously.
• Ownership mentality: you take tasks end-to-end, debug production issues independently, and iterate to deliver results without micromanagement.
   

Nice to have:

• Experience with orchestration/automation platforms (Windmill, Dagster, Prefect) — understanding how to build reliable automated workflows.
• Knowledge of RAG architectures, vector databases, and embedding pipelines — ability to build systems that work with large volumes of unstructured data.
• Experience building evaluation systems for LLMs (LangSmith, PromptFoo, or custom solutions) — understanding how to measure and improve AI product quality.
• Familiarity with Databricks / Delta Lake or Snowflake — experience working with modern data platforms.
• Experience working at product-driven tech companies or AI startups where you needed to build and iterate quickly.
• Understanding of product team metrics (DAU, retention, unit economics) and the ability to connect technical decisions to product impact.
   

Preferred tech stack:

Core:

• Languages: Python (primary), SQL
• LLM APIs: Claude API (Anthropic), OpenAI API
• Databases: PostgreSQL, ClickHouse
• Infrastructure: Docker, Git, FastAPI, Pydantic, pytest, asyncio

About your role: We’re looking for an AI Engineer who wants to build production-grade AI systems, not just experiment with demos. This is a high-ownership, greenfield role where you’ll help build our AI platform from scratch, working directly with the Head of AI.  You’ll own initiatives end-to-end — from discovery and architecture decisions to production delivery — and play a key role in shaping how AI is used across the company.

You’ll work with a modern AI stack including Claude/OpenAI/Bedrock, RAG pipelines, eval frameworks (Promptfoo, Ragas, LangSmith), and agentic patterns. This role is ideal for someone who enjoys autonomy, strong engineering ownership, and proactively identifying the next highest-leverage opportunity to drive into production.

In this role, you will:

• Design and build RAG and automation workflows inside our VPC environment.
• Create integrations across engineering, communication, and knowledge-management systems (Jira, Confluence, Slack, Google Drive, Git).
• Develop AI-powered pipelines for code quality checks, ticket auto-classification, documentation updates, release notes, and meeting summaries.
• Work on prompt engineering, model selection and routing (Haiku / Sonnet / Opus), and workflow optimization.
• Build evaluation and regression frameworks for AI workflows to prevent model-upgrade regressions.
• Create lightweight dashboards for engineering leads to surface delivery patterns and bottlenecks.
• Own initiatives end-to-end: scope → design → ship → measure → iterate.

It’s all about you:

• 5+ years of production experience with Python (services, async, API integrations, clean and testable code).
• Hands-on experience with LLM APIs in production: Anthropic Claude (Opus/Sonnet/Haiku), OpenAI, AWS Bedrock.
• Strong understanding of RAG systems: chunking, embeddings, hybrid search, re-ranking, grounding/citations.
• Prompt engineering + structured outputs + tool/function calling.
• Experience with eval/regression frameworks: Promptfoo, Ragas, LangSmith, or custom evaluation harnesses.
• Agentic patterns: ReAct, function-calling loops, fallbacks.
• Vector databases: pgvector, Pinecone.
• Workflow orchestration: n8n, Airflow, or custom orchestration systems.
• Observability: token-spend tracing, latency monitoring, model routing.
• Solid AWS fundamentals: IAM, Lambda, S3, CloudTrail — comfortable deploying inside VPC environments independently.
• CI/CD + pipeline hooks (GitLab/GitHub), webhooks, event-driven architectures.
• Basic SQL skills for analytical queries and metrics dashboards.
• Driver mindset: proactively identifies the highest-leverage opportunity and drives it to production
• B2 English level

Would be a plus:

• Real REST integrations with 2–3+ APIs
• Experience with workflow orchestration tools.
• Prompt evaluation tooling such as  LangSmith is nice to have
• Experience with Docker
• RAG experience: embeddings and vector stores (pgvector, Pinecone, or similar) for knowledge base use cases
