Work Experience

A Career Built on Precision, Systems, and Continuous Growth

Work Experience — Andres Antsiferov

Over two decades of professional life can rarely be reduced to a single narrative thread, yet looking back at the arc of my career, one theme runs consistently through every role I have held: a commitment to building systems that work reliably, at scale, and under pressure.

Work Experience

Where It All Began — Electronic Manufacturing and Mobile Repair (2000–2007)

My professional journey started on the factory floor. At Elcoteq Eesti AS, one of Estonia’s most significant electronics manufacturers at the time, I worked as a compiler-assembler of electronic products. This was not merely assembly line work — it demanded meticulous adherence to quality specifications, rapid fault resolution during testing, and technical support to colleagues across the department. It was here that I first developed an appreciation for the relationship between process discipline and product quality.

This foundation carried directly into mobile device repair. From 2001 to 2007, I worked as a Repair Master at two service centres — Sky Tec Group OÜ and STM OÜ, the latter being an authorised Nokia service centre. Handling all-complexity repairs independently, day after day, sharpens both technical diagnostics and a systematic mindset. You learn quickly that a repeatable, documented approach is not bureaucracy — it is the difference between consistent quality and costly rework.

Manufacturing, Quality Systems, and Six Sigma — Power Wave Technologies (2007–2008)

One of the most formative chapters of my career came at Power Wave Technologies Inc., a global manufacturer of mobile network infrastructure. As a Tuner, my responsibilities spanned the calibration and repair of test equipment, tuning of antenna products, and — critically — the introduction of the Six Sigma quality system into the production environment.

Working directly with the company’s factory testing teams and participating in IPC-standard soldering training cemented my understanding of quality management not as an abstract discipline, but as a set of practical, measurable tools that transform how teams work. The experience planted the seeds of what would later become a Lean Six Sigma Black Belt certification and a lasting professional interest in process optimisation.

Technical Quality Engineering at Scale — Ericsson Eesti AS (2010–2012)

Joining Ericsson Eesti AS as a Quality Controller was a significant step into enterprise-level quality assurance. Working within one of the world’s leading telecommunications equipment companies, my role encompassed debugging and documentation, source code testing, technical inspection, integrity testing, and system-level validation of communication hardware.

Crucially, this role extended beyond pure technical work. Diagnosing equipment received for repair, eliminating identified faults, conducting pre-inspection of repaired units, and contributing to the development of repair instructions and procedures all required a combination of technical depth and structured communication. Staff development and training were also part of the remit — an early signal of the direction my career would eventually take.

Repair Expertise, Training, and Knowledge Engineering — Swappie Oy (2023–2026)

The most recent chapter of my career brought together everything that preceded it. At Swappie Oy, a Finnish company specialising in the refurbishment and resale of iPhones and iPads, I served as a Repair Expert with a focus on Training and Materials.

This was not a conventional technical role. My primary output was knowledge itself: structured, multilingual, version-controlled documentation that enabled technicians across the organisation to diagnose, repair, and quality-check devices consistently and at pace.

The scope of the work was broad and demanding:

Technical documentation included step-by-step repair guides for multiple iPhone generations, disassembly procedures, hardware fault diagnostics covering components such as cameras, batteries, and charging ICs, grading standards for used devices, and troubleshooting frameworks for both routine and complex failure scenarios.

Training programme development involved designing structured onboarding modules, producing advanced content for micro-level diagnostics, and building multilingual materials to support an internationally diverse technician workforce.

Technician coaching meant hands-on sessions, one-to-one guidance on complex cases, and systematic performance evaluation — translating technical expertise into teachable, scalable practice.

Quality assurance and process standardisation brought the full weight of my earlier background to bear: defining repair standards, creating pre-, mid-, and post-repair checklists, documenting recurring errors and preventive measures, and collaborating with management to refine operational workflows.

Continuous improvement closed the loop — tracking repair outcomes, analysing error rates, and feeding insights back into both documentation and training design.

The role ended due to staff reductions in 2026. It remains the clearest expression of how my career has evolved: from hands-on technical work to systems thinking, documentation, and the transfer of expertise at an organisational level.

A Cross-Disciplinary Profile

In parallel with the roles described above, I have developed substantial competencies in web development and server administration, working extensively with WordPress, Magento 2, and WHM/cPanel environments on AlmaLinux infrastructure. I hold multiple cPanel certifications and have applied DevOps practices — CI/CD pipeline design, server hardening, performance optimisation, and security implementation — to real-world production environments.

My project management background draws on this same breadth of experience. Having operated at the intersection of technical execution, team training, quality systems, and documentation across multiple industries and languages, I bring to project leadership a perspective that is both strategic and grounded in operational reality.

In Summary

My career is not a straight line, but it is a coherent one. Each role has added a layer — technical precision, quality discipline, systems documentation, training design, infrastructure management — that informs every subsequent engagement. I am fluent in Estonian, Russian, and English, which has consistently allowed me to operate across organisational and cultural boundaries without friction.

Whether in a quality engineering, project management, or technical training capacity, I bring the same commitment: to understand how things actually work, to document that understanding clearly, and to build the systems and teams that make reliable outcomes possible.
